The person in contact before the interview gave suggestions on preparing for behaviour questions, which weren't asked at all during the interview.
This was a 1:1 on campus interview. The interviewer explained the job functions, asked about my past experiences and gave me a simple technical problem (solved using pseudo code).
I talked a lot about my past experiences with network and online services. It seemed that the interviewer was not interested in them. No questions on networking was asked.
The job function was to develop web-based configuration pages. When I asked if this referred to configuration pages for network switches or for servers, the interviewer said that Dell does not make servers now (which is false).
The interview happened 6 weeks ago and although I replied a few emails, there was no update of any kind.
