Musely interview questions

Had 3 rounds of interview, first with the VP, second was a take home test, third was two 30mins end-to-end with leads. After this, they told me I passed, and the last round should be with CEO. CEO was not respecting and cancelled the interview twice, once was 10 mins before the scheduled time, fine, rescheduled to next week. Then canceled again one day before. So guys, don't waste your time to interview this company, BIG red flag. I followed up again and the hr totally ghosted me.

Had a recruiter screen through a third party recruiter agency, recruiter was friendly. Did not move to the next stage because they were looking for someone with specific experience using a tool that I don't have experience with
