First stage was an online coding test which was fairly easy.
The second stage was the assessment center which is split between 2 written tests and 2 interviews. One of the written tests is a logical test and the other is a Java test.
The technical interview seemed a little bit hard for me, but I was first year. I think that for a second year the technical interview is decent. I received some Java and C questions, a problem to solve and some code review and testing questions. The other interview was non technical and it was a very pleasant experience.
