Bad interview experience (and reject). I would say I wasn't prepared enough for the interview since I hadn't seen the ip to cidr question and just understanding what cidr is ate away so much time from my 1 hour. Second the interviewer was highly uninterested and didn't provide any help. And kept or repeating that all test cases should pass (multiple times he mentioned that). Well I would say I buckled under pressue.

I had 3 phone screens back to back on Wed, Thu and Fri and I was exhausted because Databricks was on Friday. Don't schedule multiple interviews in the same week.
