Optiver Engineer interview questions

Very robotic company and recruitment process. Do the coding challenge, speak with HR to do behavioural. Then an engineer will smell your code and give no feedback. That's it! Poor communication process and seems very cold and harsh

1. External recruiter sells in the role to me. 2. Chat with an internal recruiter who confirms I'm the right person for it and gives me a hackerrank test. 3. The hr test is relatively easy and I manage to score around 90%. 4. Chat with #2's boss. Everything is still good and they are very excited about continuing the process with me, they are even thinking about other roles for me cause to the high score on 3. 5. #2 sends me prep material for their on-site days and schedules an interview with the team-lead of the group. 6. I have an interview with a rather grumpy team-leader. After cracking a few jokes here and there, he gets in better mood and the talk is rather pleasant. 7. After a few days of silence, I contact #2 which says the team-lead didn't think I had enough of experience, specially in subject X. Where of I answer him, "yeah, we never discussed subject X". ... and that's the end. Maybe the hr test should be re-calibrated ? I asked for feedback, which I am still waiting for.
