Jasper Technology interview questions

The interview consisted mostly of a tour of their facility with a question every now and then asking asking experience with whatever machine, product, process, etc they are showing you at the moment. They're a start up company in the vaping indurstry but they have a ton of changes that need to be made to run efficiently as possible. Was told I was a great candidate and would hear back from the interviewer very soon. The company seemed laid back and like good people but they never got back to me after countless times trying to reach out to them. Pretty unprofessional to interview and never reach back out.

1 on 1 interview with a supervisor. Lasted and 5-8 minutes. "All my interviews are short". "I'll have Hr contact you middle of next week". Sat in parking lot longer than interview.
