Delphi campus recruitment- Beware (waste of time for non-ECE students)

We had Delphi recruitment in our campus, a few days back. The technical presentation during the pre-placement talk was one of the worst we had. It was given by a technical lead. Then we had a written test consisting of 5 analytical questions, 10-12 programming questions and about 25 technical questions which covered all electronics and electrical engineering. Then, we had group discussion which was easy. All the groups were given similar topics like Lokpal bill(3 of 5 groups got the same topic).
Then the final screening was personal interviews. Here, they wanted to shortlist only ECE graduates, I don't know the reason why. The questions in interview were mix of all subjects you must have studied. So, brush your fundamentals before attending this session. If you are a non- ECE graduate from UG stream, don't waste your time. It's waste of time and effort.

ALL THE BEST!!!!!!
