There were 4 rounds of interview. 1st round of interview is pure technical and interviewer had asked questions from Informatica, SQL and Unix. Most of the questions were around scenarios with medium complexity. 2nd round is techno managerial round with 2 panelists. Questions were from Informatica with complex performance tuning and complex practical SQL questions. Managerial questions were to test our eligibility to handle users and even he asked me to draft an email to justify the user on the issues. 3rd round is Skype interview and the guy is from US who is kinda director. He simply drilled down on few technical questions along with roles and responsibilities. Final round is HR which is kinda salary discussion through phone. The process took almost 3 weeks.
