I had a great first call with the recruiter. They seemed interested in considering me for several roles. The recruiter followed up by email about next steps and asked to schedule a time to connect by phone. We scheduled a time to speak, but he never called during the scheduled time. I reached out via email about 15 minutes into the interview timeslot to check if it was still a good time to connect. The recruiter didn't respond and didn't call. After a full half hour, I emailed to schedule an alternative time. The recruiter never replied. I understand that things come up and sometimes rescheduling is necessary. But to not respond to a candidate you scheduled a call with after not calling them is a bit bizarre. I've been ghosted by companies before, but never stood up AND ghosted. Very unimpressed.
