Mukesh ji,
I am just adding my 2 cents. 6-7 months ago I was looking for job after being jobless for gap of 1 year. I initially targetted few specific companies, but things didn't worked out. So I changed my intention(yes with VK) to best desiring job for best of my capabilities. I got call from my friend who had job offer from an mnc. One other guy had denied the job offer in last minute, so my friend remembered that I too was available. I joined the company in next 2 weeks with good increment. I understand that we should have clear cut intension and burning desire, but life is pretty strange. It may offer us something much more worthwhile in long run then what we think is best at present. VK or universe knows what's the best for us. We should ideally work towards our goals with full dedication without attaching to end result(yes Bhagwat Gita philosophy). It's just my suggestion sir. I wish your son for the best in his academic and career life. Thank you.
