Three rounds of interviews and a writing test. The process was fairly quick with immediate feedback after each round. However, after the final interview, there was dead silence and when I reached out and they asked a few questions including notice period. No offer. When scheduling interviews, they didn't ask for my availability and instead just notified the schedule

Straightforward, pleasant. Generally quite cordial and even gave feedback at the end after requesting it. But they put a lot of ghost jobs on LinkedIn, so beware of that. Higher staff seem far too busy to engage it seems (at least based on the team I interacted with)
