IAS Main Exam - Essay: ALL WORK AND NO PLAY MAKES JACK A DULL BOY by Marxe Kalaimani

IAS Main Exam

Model Essay Question

ALL WORK AND NO PLAY MAKES JACK A DULL BOY 

One day, two person started cutting trees with their iron axes. They challenged each other on who would cut down more in a particular time. The first person started felling trees continuously without gap. The second person, who is physically less strong than the first, did that in different way. He cut the trees for one hour and during another one hour he spends time on sharpening the axe and on recouping his body strength by taking rest. At end of the day the second person won the challenge despite he spent less time on his work.

Work and Play – Not Mutually Exclusive

In the above story, the second  person succeeded because his sharpened axe accelerated the speed of felling trees. Likewise good play which refreshes our body and mind will not detrimental to your work.

By generally accepted view, work is set of activities which earns livelihood, and play is a set of activities which is physical and mental in nature, gives entertainment and stress relief. If you think playing is mutually exclusive to working, you are wrong. Successful people give priority to work and play equally. Lazy people would find justification by saying “I have lot of works, how can I play with the little time I have to rest?” actually they don’t understand that playing will enhance the ability to work. If you can find time in between your work to play, you can keep your body healthy and it will refresh our mind.

‘Rest’ Doesn’t Mean ‘Being Idle’

Yes, we would be tire after our work. We may well think that being idle for some time will recoup our strength. It is not so. Being idle will not bring enthusiasm back. Instead, it will pull us down further to be idle. Rather a small game we like, can make us more enthusiastic.

Playing Work

If we consider our work as ‘playing’, we won’t get tired. Would it be boring to you to pursue your hobby? If ‘painting’ is your hobby, you would love to paint all the day, wont you? Like that our work won’t be a burden if we do our work  enthusiastically as we do our hobby. Most of the people who are working in corporate find their jobs ‘boring’ after two to three years of joining. The reason is that they fail to do their work as playing or to strike a balance between working & playing.

In this globalised world, increasing competition among companies do more harm to employees. They are prevented from having a quality time for playing or to spend time with their family. This increases the stress and affects on the very health of the employees. So he/she become unproductive, which is detrimental to company’s growth so as to country’s growth. It is very essential t stop this vicious cycle by keeping workforce ‘Playful’.

Playing Studies

Mere bookish study is not as effective as practical studies. Playful practical learning is effective learning. In this competitive world, schools and colleges have become workshops that manufacture workforce for industries. They don’t bother about all round development of the children. Parents too especially from middle class family impose more mark scoring study into the minds of children. Because, they need to ensure a job for their children. They rarely allow their children to play. The result is obesity. India which is having more malnourished and stunted children also has considerable number of obese children. Other benefits of playing include mitigating the effects of pollution. We are living amidst dusts and heavy metal containing air from industries. Those heavy metals are dangerous to our health. Sweat coming out of our body can eject out heavy metals from our body. Thus playing gets importance for children living in industrial environment.

The most complicated machine in our world is nothing but our body. God has given the suitable environment on earth to nourish our body. Unfortunately our seventh sense has been destroying slowly our ambience. In this contest, playing becomes very important for our all round development. So, we can contribute more productively to the growth of our nation.

International relations and the IAS interview

P. Kanagaraj

AP

A UN Security Council meeting in progress.

Global issues and concerns are favourite topics of interview panels. So prepare well on these counts.

The arena of international politics occupies a significant place in the landscape of civil services exam personal interview. The board tends to ask questions on international issues and trends as part of general studies, current affairs or as academic pursuit of the candidates. Whenever the interviewees prefer Indian Foreign Service as a career choice the interview panel is predisposed to ask questions elaborately on global issues and concerns.

There are five broad areas of focus here: Indian foreign policy, international institutions (WTO, UNO, IMF and World Bank), international problems, international regional organisations (SAARC, ASEAN, EU, NAFTA) and the foreign policy of major powers (United States of America, Peoples Republic of China, Russia, etc).

Indian foreign policy

The interview board seeks to identify the candidates’ understanding of the elements, components and objectives of Indian foreign policy. The candidates must make a SWOT analysis of Indian foreign policy in the landscape of international diplomacy in the contemporary world, especially if students have indicated Indian Foreign Service as the first service option in the main application form. The interview panel is bound to engage more on the diverse issues, concerns, innovations, strategies and problems of Indian foreign policy including Look East Policy, Gujral Doctrine of Non-Reciprocity, Pancha Sheel Principles or Five Principles of Peaceful Coexistence, Look East and Link West Policy, FDI (First Develop India) and modifications in foreign policy under the new government.

India stands at the threshold of a new era of economic growth, military might, science and technology achievements and a largely successful democratic model of governance. Students must analyse the major advantages of India, especially the vital components of its expanding soft power resources. Past panels have asked the candidates to display the array of arguments that can be advocated to demand a place for India in the permanent membership of the Security Council of the United Nations Organization. Candidates can concentrate on preparing arguments such as the expanding economy, second largest population, seventh largest geography, function democracy, impressive military capabilities and equally admirable self-restrained military behaviour, constructive and peace-loving diplomacy and steadfast adherence to the basic charter and objectives of United Nations Organization, greater participation in the numerous peace-keeping operations of UNO in many continents and countries so as to bolster India’s case for a permanent membership of the Security Council.

New terms and concepts

Candidates ought to study comprehensively the new concepts in international policies, economics and relations and such a detailed preparation will pay rich dividends in the written tests of the civil services exam, especially in the General Studies Papers 1 and 2 and General Essay of the main test, too. For example, concepts like Soft State, Overdeveloped State, Failed State, ISIS, Orphan States are debated in the realm of international politics. Last year, the interview panel asked a candidate probing questions on the over powering presence of the military in the democratic political life of Pakistan and in the course of the discursive engagement it asked the candidate a specific factual question as to what is meant by the term “Milbus.”

The candidate answered that the term “Milbus” is a neologism from the combination of two words military and business and was coined by the Pakistani academic Ayesha Siddiqa. It refers to the non-military economic activities of the army which in normal democratic politics will be outside the professional domain of the military falling under the sphere of civil society and the State.

Candidates should concentrate on understanding and analysing the new concepts and doctrines and the opportunities offered through these new concepts can prove to be most fortuitous ones for the candidates.

American policy

The foreign policy of the United States of America has considerable significance in the personal interview of the civil services exam. Pax Americana rules the world in the last two decades after the breaking down of the Union of Soviet Socialist Republic and collapse of communism and the nature of its influence in the international system is of utmost importance for interview candidates. The Islamic State, Kobane Battle, Afghanistan crisis, American stand on multilateral environmental conferences, AFPAK policy, Asia Pivot policy, clash of civilization theory, drone attacks in Pakistan, Emerging American Chinese rivalry, American economic slowdown and its repercussions on world economy, energy diplomacy, earlier doctrine of Isolationism, American Russian relations in the contemporary world, Indian American relations in the post-Cold War era are among the plethora of issues and concerns, concepts and strategies that the civil services career aspirants must thoroughly prepare.

International organisations

International organisations and institutions such as the United Nations Organization, International Bank of Reconstruction and Development, International Monetary Fund and regional international organizations like SAAR, ASEAN, EU, NAFTA play a prominent role in the personality test of the civil services exam. The challenges that each of these organisations grapples with are significant aspects, especially concerning Indian interests and priorities. The panel tends to ask questions on the structural and functional reforms that are needed to be infused into UNO as new issues and forces impinge on its functioning such as deepening environmental crisis, irresolvable North-South inequalities and the demand for the democratisation of global institutions.

Cracking IAS: The Personal Interview edge

Cracking IPS: The PI edge

P. Kanagaraj

The Hindu

Mock interview

Be your best self at the civil services’ personality interview. Here’s how.

The Union Public Service Commission will soon conduct the personal interview for one of the most prestigious and competitive examinations in the country — the civil services exam. Approximately 2,000 candidates will attend the personality test, competing for around 1,000 vacancies in the services included in the civil services category. Though the personal interview carries only 275 marks out of the total 2025, the stakes are very high here as the students can gain decisive edge over others in a relatively short span of twenty to twenty-five minutes. Ideally, the candidates should aim for a score of around 60 to 65 per cent to come out in flying colours in the exam.

The entire civil services exam’s personal interview can be summarised in one question of the board to the candidate — to explain who he is. The panel conducts the interview to identify the intellectual and attitudinal attributes of the candidates, such as grasp of narratives and arguments, reasoning ability, appreciation of different perspectives, range and depth of interests and personal attributes that are relevant for interaction with people.

The interviewees ought to prepare exhaustively about their name, educational subjects and institutions, native district, town and State along with national and international issues. Each word they fill in the data sheet, along with main application form, is a micro reservoir of potential questions that may be asked in the actual interview. Therefore, the candidates should pay meticulous attention to all of them.

Hobbies

The panel asks lots of questions on the hobbies and extracurricular activities of the candidates as mentioned by them in the data summary sheet. When candidates prepare for the civil services exam they have to undergo a rigorous work schedule often for months leading to the main examination.

In this gruelling phase, they need appropriate rest. Hobbies become important here as they provide for the rejuvenation of mind, soul and body. Moreover, the candidates, through productive and profound hobbies, can manoeuvre the course of the interview into their own areas of strength by discussing their hobbies and interests. The students in the past have chosen many hobbies ranging from the mundane ones to extraordinary ones. For example, reading about aliens, interests in wildlife and yoga and meditation were some of the hobbies cited by candidates in the past.

In one instance, a candidate attended the personality interview with an interest in alien life as hobby and the interview panel posed him a cascade of questions that included – Who are aliens? What is the SETI project? What are UFOs and flying saucers? What is the necessity of missions like the Mars Orbiter Mission of ISRO and Curiosity mission of NASA? How would life have evolved on this planet? As he had anticipated these questions, he was thoroughly prepared and therefore answered them impressively.

Educational institutions

The personal interview panel also focuses on the almamater of the candidates. If the candidates have completed their studies in prestigious institutions, the panel invariably questions them comprehensively about the motto, vision, origin, emblem, alumni, distinguished faculty, academic rigour, intra-campus politics and democracy, cultural activities, research contributions, sources and nature of funding, major problems and lacunae etc.

Sports

As the civil services personal interview panel adopts a holistic perspective towards judging the personality of the candidates, it consciously poses questions on sports and games, especially if the candidates have pursued some game or sport in their schools and colleges. Once, a candidate attended the civil services personality test stating that hockey was his hobby and panel spent a considerable portion of the personal interview asking him questions on hockey. He was asked to explain the causes and factors that precipitated the stultification and marginalisation of Indian hockey. As a past player of the game, he explained the multiple factors such as the vertical split in the hockey powerhouse of Punjab due to partition in 1947, emergence of a new breed of hockey called continental hockey or total hockey where stamina and speed are more important than skills and magic of oriental tradition, introduction of artificial and synthetic turf, major alterations in the rules and regulations and architecture of the game that inevitably favoured the western style of hockey. As it was a thoroughgoing analysis of the numerous forces and factors, the board was greatly impressed and the candidate cornered a lion’s share of the interview marks, which enabled him to enter the coveted Indian Administrative Service.

Domicile

The interview panel is likely to ask a plethora of questions on the native town, city and district of the individual candidates. A thorough understanding of politics, economy, society, culture, art and architecture of the domicile of the candidates constitutes a fulcrum of any successful strategy. For example, when a candidate hailing from Bengaluru attended the personal interview a few years back, the panel posed umpteen questions on the contemporary and historical events of the city.

An ideal preparation should cover in a comprehensive manner the multifarious aspects such as salubrious climate, status as IT hub of India, performance of major information technology companies, place of Bengaluru in the cricket landscape of India, various educational institutions of national repute like IISc and IIM, national industrial giants like BEL, scientific institutions like ISRO and problems and challenges in urban governance and Deccan plateau. Similarly, the students hailing from Karnataka in general and Mysuru in particular should prepare on the nomenclature, Mysuru as cultural capital of Karnataka, Cauvery river water dispute, Chamundeswari Temple, Woodaiyar Dynasty, Hyder Ali, Tippu Sultan etc.

General suggestions

Candidates should study objectively their strengths and weakness so that necessary measures for progress can be designed and implemented. They should apply SWOC analysis to test their personality and to identify their strength, weakness, opportunities and challenges and formulate remedial measures in consultation with experts so that the ultimate hurdle of personal interview in the civil services exam can be conquered.

Honesty

The interview panel believes that honesty is an intrinsic and indispensable ingredient for a career in civil services, and, therefore, it looks for a morally clean personality. Students should not indulge in dodging, pretending or vacillating tactics in the personal interview of the civil services exam. Dissembling personalities are just not desirable for a career in civil services. The panel always believes in the maxim that trustworthy personalities will become praiseworthy bureaucrats in the future.

Stress management

During the course of the personality test, the interview panel may begin to fire cumbersome questions and put the candidates under enormous unremitting pressure to see how they handle unfamiliar, embarrassing and psychologically disruptive circumstances. On such occasions, the aspirants should maintain their composure and not succumb to pressure. The interviewee must remember that adversity holds many opportunities and that achievers in all walks of life reached their glorious destinations only in spite of pain and not because of its absence. They need to cultivate a positive outlook and progressive mindset and their strategy should be to hope for the best and be prepared to face the worst.

Luck

There are certain fortuitous circumstances that influence the course and final outcome of the personality test, and any amount of scientific planning and systematic preparation may come to nought if fortune decides to desert us. We have not developed a technology or a philosophy or a methodology that will enable us to achieve mastery over the luck factor, and, therefore, the candidates should be positive and focused without worrying about unforeseen circumstances. Remember that luck is nothing but a fortuitous rendezvous between thorough preparation and tantalising opportunity. Be yourself and be the best of your self.

UPSC defers civil services results, wants clear stand on Jat quota

• HT Correspondent, Hindustan Times, New Delhi

• Updated: Mar 27, 2015 19:04 IST

The Union Public Services Commission building, New Delhi

---

The Union Public Service Commission (UPSC) has deferred results of the civil services examination due to the Supreme Court verdict scrapping Jat reservation and has asked the government to take a stand on their exclusion from the OBC quota.
The UPSC declares the results of the Civil Services (Main) Examination in mid-March. This is the second of the three-tier civil services examination to recruit bureaucrats for key civil services including the IAS and the IPS. Only those declared successful at the Main examination are interviewed at the third stage.
The UPSC communication came in the backdrop of Jat leaders lobbying with the government, and the BJP, to take steps to restore the quota benefits. On Thursday, Prime Minister Narendra Modi told a 70-member delegation of Jat leaders that the government was studying the verdict and “will try to find a solution to the issue within the legal framework”.
Party sources said finance minister Arun Jaitley would be requested to look into the matter since it involves legal issues as well.
The civil services exam is the first major recruitment examination that would be impacted by the SC verdict striking down last year’s order extending OBC quota benefits for Jats living in 9 states including Bihar, Gujarat, Haryana, UP and Delhi.
Sources said the UPSC had primarily approached the government to confirm that Jat candidates — who had applied as OBC candidates — should be treated as general category.
“The matter has been referred to the law ministry for its opinion. The decision will be conveyed in a day or two,” a government source said, indicating that UPSC would be advised to treat Jat community candidates as general category.
In due course, the government would also have to take a call on the fate of Jat candidates who may have been selected on the basis of their new-found OBC status last year.

Words are stronger than two edged knife

One can damage the enemy with the every move of two edged sword.  For the soldier going to war, two edged sword is not alone sufficient to make him kill others. He needs inspirations to do it. He needs to be informed the purpose of the war with the carefully codified words for the purpose. Proper use of words can accomplish greater tasks which are not achievable by strength of armies and navies. Words can be used in both ways of negative and positive. If we look at history, words have been used to either create social orders and peace or to destroy the order and peace.

The writings of Rousseau and others inspired  great number of masses that led to French revolution, which familiarized the idea of freedom and liberty. Words were positively used by Rousseau. Contrary words were used by Mario Antoinette, the French queen at that time, in negative way which angered the same French people. When hungry people of France asked bread she replied sarcastically, “if they don’t have bread, let them have cake”. This statement angered the French people. The words of monarch could not prevent the revolution.

First world war could have been averted, if they handled words more diplomatically. After the French defeat by Germany, Germany took over the French parts of Alsace and Lorraine. France was treated badly by Germany. This happened in the course of Germany unification. This instilled a sense of revenge in French people. After first world war, the arrangements were done to create the platform to share and rectify the diplomatic disputes by creating League of Nations. But, this was a failure for variety of reasons.

Indian Nationalism and Gandhi

Freedom fighters along with Mahatma Gandhi were able to mobilize great number of masses only by writings and speeches. They had no swords and guns but their sharper words driven away the British from India. India had plenty of social problems more than today. The sharper words of social reformists  slayed the ills of the society.

During the inter war period, antisemitism was preached by Hitler. He was quite successful in it. He mobilized large number of Germans to support his attempt to eliminate Jews. His words had done a negative thing that will affect the peace of the society.

Its all about use of words

After second world war, world powers learnt their lessons and created a updated International Platform to address the issues between the nations in name of ‘Unite Nations’. Its purpose was all about brain washing the countries to not to opt for swords (War) but for words (diplomatic dialogue)

Nelson Mandela of South Africa was in prison for 27 years. He had no swords, but his sharper words made him powerful. Later his policy of non-violence and forgiveness towards whites helped South Africa to become one of the emerging economies.

Choice between word and sword

After independence, conflicts between India and Pakistan seem never ending. Every time if there was clash between two armies along line of control, they would stop the dialogue process, only to resume it after one year. Dialogue (Word) and war (Swords) have been chosen alternatively by the two countries. But now the two countries are having nuclear weapons which can devastate both the nations. Both nations should opt out dialogue process for the greater benefit of two nations which are having so many common problems.

Words can create revolutions

We can hear the words like “Arab spring, umbrella revolutions”. What are they? These pro-democracy revolutions organized by young people of those countries only by sharing words in the social media like Face book, Twitter. Now a days these sites are used by various pressure groups to mobilize support for various course.

In this globalised and polluted world the role of words and consensus achievable by it among countries are very essential for the very survival of biosphere on earth. Because of emission of green house gasses, the potential climate change is waiting to show its monster face. International dialogue process to avert the climate change is essential in this hour, so that every country will reduce its green house gas emissions in the future. No swords can be invented for the purpose. Thus the utility of words is broader than sword.

We have international groupings for all our common problems to make census by words, which cannot be achievable by swords (Domination). The use of words is not only sharper and stronger, but also desirable one in this globalised world to maintain peace.
