Qualcomm Software Engineer interview questions

Ghosted after a nightmare of an interview process. Screening interview went pretty well, I moved on to five remote interviews with various team members. None of the interviews went according to schedule. Zero. Two substitutes (day-of), two reschedules (...also day of). Two interviewers didn't have their camera on. Last scheduled interviewer, the site lead, completely whiffed, then rescheduled. Post interview, they added "homework" in the form of a follow-up email. I heard nothing from them until I followed up three weeks later, at which point I got an "oops" and a rejection. Yeesh. This was all for a position that they hadn't even secured office space for yet, which I only found out after asking questions about the very generic position listing. For what it's worth, the engineers themselves seemed pretty cool, and it sounds like the interviews were thrown on them at the last second. Interviews themselves seemed fairly standard, some live coding, OS questions, driver framework stuff. Didn't get any behavioral questions.
