Interview
The firm seems reasonable on paper. But it looks like they don't know how to interview candidates not coming from Ph.D. backgrounds properly.
They have taken three interviews out of a planned 5 for the position before rejecting me, but it seems like they were too stuck on seeking a specific solution to a problem they have in their mind, especially for Hackerrank exercises. They asked to solve problems in hackerrank, but the platform didn't work properly, most of the time, resulting in a substantial waste of time too.
The interviewees seemed a bit rude and elitist and refused to assist when stuck on some problem during the interview.
Overall a big red flag I can see regarding the company's culture.
