Process
HR call with a good introduction, then a 45-minute HM call. Next was a take-home project. It was a kindergarten-level Python code base, and my job was to leave comments. I left comments on basically every single line, but I still failed. There was no valuable feedback, making it a total waste of time.
Questions
Comment on an ugly Python-based CRUD service with MySQL.
