Intel Corporation interview questions

First I had a phone interview with some general questions about circuits(like transistor, op amps) and then some question on testing of circuits and oscilloscopes. After abt a week I got a call saying that I was selected for an onsite interview. The on site consisted of four rounds with three technical rounds and the last one was behavioural. I guess I did not do well in one of the technical rounds. After 2 weeks I was rejected for the job.
