Qualcomm Senior Software Developer interview questions

One of the most vague interview processes. Interviewed for a role related to autonomous driving. The HR sent an email to schedule the interview. The interview was scheduled with a Technical member working in a different team. I had zero idea of what to expect during the interview. Despite sending two emails to HR on what to expect no reply. So I went to the interview with wide expectations. The interview was more on some basis and nothing related to the role. I was informed two days later that they were not proceeding further.
