Lorien Project Manager interview questions

A recruiter reached out to me about a contract PM role and asked me to book time through her Calendly to discuss the position in more detail. She also requested a copy of my resume before the call. After we confirmed a date and time, she asked to move it earlier, explaining she was concerned the application portal might close. I agreed, but on the day of the interview she canceled the call without providing a clear reason, even when I followed up. The whole experience felt very unprofessional.
