Qualcomm Engineer interview questions

First, HR will contact you about the time you are free, then have phone interview, if you can pass it, then it will come up with a face-to-face interview in Qualcomm office.

There was one technical round and one HR round. Each round took around 30 mins. In the first round, the interviewer asked me a few questions on various signal processing concepts (my area of specialization). Apparently, I got through the technical round and was asked to wait for the HR round. I waited for hours but the interview didn't happen. The panel outright rejected the candidates who they were not able to interview because of time constraints (that's what they say). I did not expect this from such a reputed company. Maybe they weren't really interested.
