Interview with recruiter, interview with HM that involves some debugging, take home involving implementing a spec for a protocol parser. Liked the process, likes the people, thought it was a fair evaluation. Got ghosted after turning in the take home though - sent two emails and never heard anything .

I applied online. The process took 3 weeks. I interviewed at GreyNoise in Dec 2024
Interview
Typical interview process (HM -> Technical Rounds -> Exec level). 4 interviews in total. Fair questions, although some rounds felt too unstructured when the interviewers didn't have clear questions. As a candidate, you want to send the right signals. It's hard to do that when the interviewer didn't prepare. Communication was clear throughout the process, which took ~3 weeks end-to-end.
Two main complaints: First, salary expectations were not clear from the beginning. Second, after making it to the final round and speaking with executive leadership, I'd expect to receive feedback or a phone call about why things didn't work out. Instead, I received a generic 'thank you for your interest email.' I thought that wasn't a good way to show respect for candidates who invested that much in the process.

Interview
The interview experience was unprofessional. The types of questions I was getting were not appropriate for the position’s level; they were incredibly basic. Additionally, they were very rude. I declined to move forward with the rest of the process.
