I was referred about 4 months ago. Had multiple stages and then was completely ghosted despite following up. A few months later a new recruiter reached out to me about a similar role, not knowing about the previous interview process. I took the call but was very upfront about the interview process I went through a few months prior. She scheduled my next round with a different recruiter, which was 1 hour long. I did great in that interview and the new recruiter said they'd be in touch by EOD to schedule my next round. The next day I followed up because I didn't hear back. She said sorry for the bad news but I didn't know you interviewed with us earlier in the year and it's against our policy to be able to go through this next stage within 12 months. I'm not sure if they were even planning on proactively telling me that or not before I had followed up, but either way it was 2 examples of awful communication both internally and externally. The first recruiter that reached out to me apparently didn't check anything in the system, wasn't aware of the policy, and must not have informed the next recruiter about my interview process recently that I was very upfront about. It was unprofessional the first time and just a waste of everyone's time in the more recent process.

It was very professional and clear. A little bit longer then expected. HR is quite professional and dedicated to find best candidates step by step.. there are 4 different sessions and every session is challenging.
