Had an interview with the recruiter and received a reply weeks later. I had assumed they weren't interest since so much time had passed. The reply that finally came stated that they were impressed and wanted to move forward. I scheduled my second interview and then received a reply that they were not moving forward with my candidacy. Why did they ask me to schedule a second interview if they had no intention of interviewing me? Why did weeks go by before any follow up from the first interview? Horrible way to treat a candidate.

I had one or two phone screening (HR + technical). I was then asked to work on a challenge. The goal was to find as many vulnerabilities as possible in a web app and report the findings back. I did not do great and they decided to not move further. The job description mentioned appsec and netsec skillset although the interview was very much appsec oriented. They were really reactive and the overall process was quite enjoyable.
