I applied through college or university. I interviewed at Qualcomm
Interview
Interview was great. They asked all basics to standard questions. Interview went well and it was 2 hours long interview. But didn't get selected for HR round. I answered almost all the questions.
Had 5 different interviewers with questions with medium leet code questions to some in depth OS questions. Some of the questions were difficult and the team seemed a bit unorganized and repetitive in the interviews but overall it was fine.

I applied online. I interviewed at Qualcomm (San Diego, CA) in Jul 2019
Interview
6 rounds of interviews with a quick first round briefing then technical questions from engineers from each team. Each round is about 45 minutes with some breaks in between. They expect you to talk through solutions with them to problems they give you and give clear coherent answers.
