One screen call with internal recruiter and two virtual interviews with hiring manager and another in the company. Quick response from the hiring manager after screening call. Scheduled back to back

Received an email after 5pm saying will schedule an interview by 9am in the next morning. But I already scheduled a meeting so will not be available on the next day. I e-mailed them back to reschedule a time on Wednesday in 10 mins, but no reply until noon on Tuesday (I e-mailed them for a follow-up). They said they will give me a call a Wednesday but did not give me a time, so I waited for this call all day on Wednesday.
