RallyX interview questions

The recruiter ghosted me and never joined our first scheduled screening call on Teams. I sat waiting for 20 minutes. I immediately emailed them and asked if there were any issues, or need to reschedule. They did not email me back until 4 days later and said that “Teams did not show anyone was waiting in the lobby”. No apology or anything. I am not sure how this would work and have never had any issues interviewing on Teams. They asked me to reschedule but I did not move forward with this company. The whole thing seemed very unprofessional and I was no longer interested in working for RallyX.
