Snap interview questions

Initial conversation with a recruiter, scheduled a technical screen. They canceled one day before, rescheduled for the next week. Next week, I joined the call, waited for 15 minutes and the interviewer just didn't show up! Eventually, they apologized and rescheduled again. Finally, had a screen last week, it went very well, questions were SQL and simple stats, easy level. It look them a week to get back to me only to inform me that I didn't pass. Such a waste of my time! I'd avoid this company honestly.
