The interview process was standard for this type of role: recruiter screen, hiring manager, followed by a loop. I was not impressed with the hiring manager. Beyond spending 10 mins discussing a technical challenge/project I've worked on, he didn't ask any follow-ups or additional questions on my experience. Additionally he was late and yawning throughout the interview. We spent the majority of the 1 hour call going over a random quadratic formula question in Google Docs. I failed to preemptively include some error handling, which likely was his deciding factor in passing on me. Very odd criteria for selecting a Sr. SWE (backend) focusing on data orchestration and API integrations. Would not recommend.
