Abbott Senior Software Engineer interview questions

Recruiter sent an email to check availability. Apparently recruiter had a conflict and couldn't join with no prior notice. Reschedule to a later time- this time i Joined the meeting and was waiting for the recruiter to join for 10 minutes. After i sent an email whether he could join then he joined. After that call coordinator sent me link to pick availability. Again same story repeats, now interviewer did not join the call. I asked to reschedule and they ghosted me.
