Principal were hiring on-campus for Trainee Developer/Trainee Analyst. Round 1: Basic quants aptitude test. Around 30 questions. Enough time if you know the formulas. Round 2: e-Litmus Test. They had 3 sections, Quants, Logical Reasoning and Verbal Ability. It was tough. Check e-Litmus online, you'll find a sample paper or something. Round 3: They ask you to write an answer to where do you see yourself in 5 years. Face-to-face interview. Prepare algorithms and know everything which you have put on your resume. Give clear and concise answers. I was rejected after this round but I have heard further rounds consist of a puzzle round and an HR interview.
