My experience of campus placement in Mumbai.
Round 1: Aptitude(Quants and English) - Easy
If you have Average aptitude skills you should clear this easily.
Round 2: Programming with pen and paper: Four Programming questions were asked - two on patterns and two on arrays. The difficulty was easy. The programs were awarded one/half/zero, based on the evaluation done by the one who checks the code( Yes they were checked manually).
If you are able to score more than or equal to 2, you are selected for the next round which is:
F2F Technical interview: wherein I was asked questions on OOPS concepts, Database, basic programs on String and patterns and resume. This is to check whether you are a technical person or not.
If you perform well in this interview, you might be directly called to their Office at Dadar. Where The Salary, service agreement and everything is discussed (That means you have got the job).
