Interviewed Apr 2012 in San Diego, CA (took 3 weeks)
After the my technical Phone interview which took almost a month i received an invitation for the on-site interview at San Diego, CA, followed by interview dates available & choice followed by confirmation and procedure for purchasing the airline tickets & hotel reservation. Received Interviewers names 2 days ahead on the scheduled date. I had 7 professionals interviewed me starting with HR and remaining from different departments (Technologies) of modem testing. Received interview schedule & locations of the interviewers from HR. The interview lasted for 7 hrs each 45 minutes & remaining transport (Shuttle Service Available) between building within the Qualcomm campus area & Lunch All the travel expenses taken care by Qualcomm. Overall it was good experience of having multiple interviews and you can also learn a lot. Practice makes man perfect. All the questions were based out of my resume & experience. Make sure you are perfect on the concepts mentioned in your resume.
