Qualcomm Software Engineer interview questions

At first there was an hour long phone interview. It was good, interviewer was friendly. Then they asked me to visit their San deago location for onsite interview. Interviewers were somewhat rude and just boasted what they do and you feels like you are nothing against them. It was really demotivated situation for me. After going down there they told me it's very senior level position which was conflicting what was told in telephonic interview.
