To have a quick judgement about the person, I believe nothing is better than throwing before him/her some puzzles (mathematical/ analytical/ programming problems) and see the approach. I received back-to-back 4 problems after a quick and brief introduction. The coding problems I got were way too easy (just basics: searching & mathematical). The harder part of this round was the puzzles (tricky, mathematical, related to probability). At last, I was asked a question on DBMS and the interviewer asked if I know JAVA.
