There was first pen and paper consisting of few technical and aptitude questions. Then 1 technical and 1 hr interview. Interview was on skype and interviewer seems to harry so it took only 20 minutes. The interviewer looked determined to prove that he is better than the interviewee by picking direct questions from the web and shifting to another copied question from the web within minutes without providing adequate.comprised of two Java questions(merge two lists and basic hashing based on vectors), SQL questions and some advanced networking questions, followed by a Skype interview..They also asked me questions based on my resume. There are also other job role also so they select only students who have knowledge BI.
