Qualcomm CPU Test Code Development Engineer interview questions

It was contract position at Qualcomm. Scheduled phone interview. From start, it seemed that manager was not interested in interviewing and was very rude. Asked random questions. Wasn't open to solutions and was adamant on his solution to problem. Call lasted for 20 min. He was so rude that he neither greeted at start of the call nor at the end. After one week received rejection email.
