Application

I applied online. I interviewed at Qualcomm (San Diego, CA) in Apr 2017

Interview

They contacted me two months after I applied online. The first interview was technical which I easily passed. Then I went onsite to give a talk and for further interviews. I did great in the interview and two weeks later I got an email from the HR that I passed the interview and got a pending offer. We even discussed numbers. The HR then stopped responding to my emails. I finally chatted with hiring manager and it turned out that they had given offer to multiple people. Very unprofessional. Qualcomm is taking its path down to a 3rd tier company.

Interview Questions
  • They asked general math, signal processing, and machine learning questions.
