Phone interview was nice with one simple question about hashing and one nice math tricky question The on-site interview was based on 5 robotp-engineers activating running a pre-programmed interview sessions they received from HR/their manager. I felt they were there just as a input/output port to/from the hiring manager. In two of the interviews The interviewer showed some basic lack of understanding of the stuff related to the question he asked. In one case, the interviewer didn't really understand what's the pivot in quick select and in other he didn't know to find complexity of a recursive algorithm by the regression of the T() . I think I have very good interviews in 4 sessions though I missed few opportunities to knock them down . I feel I should have been more aggressive to take over the interview flow and thus be able to demonstrate thinking skills . They in general pull you to the lower level of get the solution and then you might miss the real thing which is the skills you should prove in the way. Who cares how many golf balls you can put inside a buss or ho good how you in estimating the size of the buss. One interview I screw up and I guess that's what failed me. Friends told me you must get all the interviewers vote for you. .
