MKS Instruments Communications Specialist interview questions

Recruiter missed our initial call and left a voicemail (calling me the wrong name) and emailed to apologize. We rescheduled for the next day. Following the call, the recruiter wanted to schedule me for a second round interview the following day. I had no flexibility for the next day, so the recruiter sent over times for the following week. I picked a timeslot and never heard back. The recruiter missing the first call was a major red flag but we're all human, so I decided to move forward. Overall odd experience.
