If you are looking for a top job, you can as well tie a 8 pound to your neck and jump of the nearest bridge!!! You will be provided with golden handcuffs, asked to chain yourself and throw away the key. Be prepared then to be flogged and conditioned continuously till you are subjugated to absolute obedience. I have heard of a guy breaking down to tears after consistent and unbroken torture of words and shouting.
If you are joining the place then be sure to bid good bye to any personal life and don't dream of any vestige of self-respect. You will be continuosly abused, whether you do a good job or not and also be conditioned to enjoy this torture!!
Many poeple recruited in the past 2-3 years at top jobs and could not last long. One guy who was asked to leave in a short span, went into a long depression and heard he is yet to recover from his depression. Another person was so disgusted that he quit in a year and his exit interview feedback was so hard hitting that HR deemed it fit for the dustbin rather than pass up the honest feedback. A couple of more people are getting used to being target practice. Another is using all his bureaucratic skills to hang on.
Most guys undergo this torture silently, while some have a constant crib life in the company but do nothing about it.
Ask around, do your probing, try and get feedbacks from those who left rather than those inside. Look at the track record of people who have left the company in the last 2-3 years. Ask yourself why so many people at the top have left? If you still feel upto it and you are made of sterner stuff or there is equal torture in your current work place, then do take the plunge.
