Remora interview questions

Their interview process needs some improvements. After multiple rounds of interviews, I was then given a project (which I have never had to do in a hiring process) and was told that it would only take an hour to complete—not true. More like 3 hours. And after putting so much effort into it, I was completely ghosted. I followed up and still did not hear back. Extremely inconsiderate to those who are serious about finding employment. The lack of communication needs to be addressed. Super red flag.
