DataGuard Engineering Manager interview questions

After submitting for the Engineering Manager position, I received an email from their HR to book my interview, and it was rescheduled for the first time 45 minutes before the interview time. After rescheduling, the interview was again cancelled, and I was asked to reschedule again, but this time, 2 minutes after the meeting time, when I was already waiting on the call. The HR is a complete disaster. Avoid them at all costs and find another professional employer.
