Which is the best company to work for in India?

Best is too vague a term for answering this question.

A company can be best for one person but can be a nightmare for another.

Please know that a company should be chosen as best or worst based on the importance you give to the following criteria:

Money, Power, passion, work satisfaction, job security, work culture, work -life balance, opportunities to learn, location, opportunities for higher study,  Perks and Perquisite, and so on.

• Google may be a dream company for many but someone who wants to start a company of his own might not feel that Google is the best company (I mean he will not stick to Google always)
• L&T is well respected  as the Largest Engineering based company in India but not everyone feels that it is the best place to work for. In fact, you can go crazy to see the diversity in response!!!
• NTPC/ONGC/BHEL and other PSUs are a dream job for most Indians but I know people who have quit those jobs to join companies like Flipkart
• My sister is an awesome coder but couldn't make it to Deloitte however her friend who was terrible at coding but had outstanding communication skills got through it. ( Before Deloitte came, I was telling her that it the one of the best company for you. Yesterday I told her, Deloitte was not good for you. You must go to a company where you get an opportunity to write brilliant codes. You can say grapes are sour but one can't fret over one lost opportunity. Isn't it?
