I got my first interview from University career fair. The people are really great. They will listen to you and ask you some interesting questions.
After the first round which was for 30 min, I got a call for the 2nd round of interview and it was a panel interview round. They will test you as a person both professionally and personally. They will provide you enough time to express and it simply depends on you, how you speak, because, that will drive the interview. If you really want to work with DPR and has that passion towards construction, then it will be a piece of cake for you. They are really selective and will test you to the core.
