Hii Pankaj,

If you wnat to persue masters in Engineering,then definately you should prepare for GATE.

because if you will do M-Tech from IITs or NITs then it will be very helpful for your bright future.

also you can get a Government job by your GATE rank.

and many MNCs take employee on there GATE rank.

also your master degree will help you for VISA in your future.

But if you are from a computer science back ground then you should focus on getting a job.

because in IT industry no one will ask you for your degree.every one will see your work.

So it's up to you ,what you want.

hope you understand

thank you
