There was a face to face interview for the position that I applied. The interview was Ok but the interviewer didn't ask a single question related to WPF apart from what was written in resume. I really doubt that the interviewer knew WPF. Than they ask to work for another profile. I went ahead to give interview for another profile but instead I was asked to give a aptitude test despite having experience. The aptitude was fairly easy. Once that completed again had a face to face interview which was moderately difficult.
