Hello!

Both DTU and NSIT are prestigious colleges which have  high cutoffs for CS and IT. Being one of the most sought after colleges, both face good placement season. If there are less seats in DTU then even getting that seat is very difficult which means that even those handful of students are very good in their field. Also, you should know this that companies visit no matter what and if you have talent then you'll be hired for sure.

For sure, you'll have to go through several screening process but it will only fill you with confidence and make you ready for the final interview day.
