However your interview go at the end of the day they'll ask you to join paid internship at Primus. They won't ask you any practical questions and will judge your practical skills. If you are strong enough to pay 80000 for internship then everything is yours.
I had 3 rounds. 2 technical and 1 HR. The experience was smooth but took an entire day (normal IT interview length). All questions were about ABAP. All were technical. Over all it was a smooth experience.

This is the first place that has got no interview; rather you show confidently that you could fool the client ; and the job is yours. Sometimes ; if they have not got any client ; then just to bother you around ; they take 3 reviews and if the ckient is ready for implementation ; well they tell you that you have 3 years for experience and you got to go there and fool the client into doing yiur work.
