How to get into DTU?Hope you have known the follwing steps.

One needs to take the JEE (Main) exam.

One also needs to secure at least 60% marks (55% for OBC-NCL, 50% for SC/ST/PwD) in aggregate of Physics, Chemistry and Mathematics in Class XII.

Admissions are done on the basis of rank in JEE (Main) through JAC Delhi Counselling.

Now coming to your questions you have to justify why was there a gap of 2 years, when you face interview during placements. If you can justify with conviction and proper reasoning, then should not be any problem. However having a 2 year gap between your class XII and engineering will not act in your favour. You have to get very good marks in 3rd and 4th year, to nullify this drawback.

hope you find it helpful

Thanks

Good luck
