This is easy for an intern. Just follow the reviews here. Read what other people posted. I spent a whole weekend studying for the interview, and most of the questions came up.

I had to take an online assessment with multiple-choice questions. It had roughly 20 questions on OOAD concepts and coding snippets. The next round was a technical and behavioral interview, which lasted for 30 minutes.

Worst feedback ever received after the final round. They will reject you if you are on F-1. So, don't apply there and don't waste your time applying and interviewing.
