TuSimple Sensor Applications Engineer interview questions

Interviewer was late and only asked three questions about skills not mentioned in interview. Whole interview lasted 3 minutes. Even though I didn't have those skills, I was sent to another technical interview on the position where I was asked about even more skills not mentioned in the job description. Was told I would hear back in a few days and haven't heard back three weeks later. Unprofessional interview process and one of the worst job descriptions I've ever seen.
