Lucid Software Associate Product Manager interview questions

The first interview with a PM was a case study. It seemed reasonably challenging and I made it to the next level. The recruiter informed me that I'd be interviewing the entire team for the next round. In the middle of my interview with the design team, I was informed that there are scheduling conflicts with the next set of interviews. I emailed the recruiter immediately to ask her for a suitable time but she didn't respond to my mail. The next day, I get a standard automatic email that I have been rejected. It seemed unprofessional to waste my time. A PM candidate cannot be judged on incomplete interviews. I'd expect to either get rejected after first round or complete my interviews with the entire team in the next round. This left a bad taste and I wouldn't consider applying again.
