Amazon Software Development Engineer interview questions

Passed the OA and got the comfirmation email for the final VO, then after 2 weeks I was notified the VO was cancelled due to limited headcounts, and the HR helps transfer my interview to another team and got another VO, then two days after confirming the new VO date, it was cancelled again, due to limitied availablies as well.

The interview was for 30 minutes and I was asked both the online assessments questions. I was waiting for behavioral questions to jump on but the interviewer simple said that the interview is done.
