Someone once asked...
Someone answered with kindness...
As a btech final year student, I can say that you should be worried about future but in a good way. Try to acquire some skills other than your degree and also find what u really want to do. My brother was also a btech student and after he completed his course he was unemployed for almost a year, but he never gave up and now he is working at dubai and he is doing quite well. Worrying is good till a certain level. Dont loose your sleep or get addicted to anything due to this worryness and it will all turn out good
