Coding Technical Behavioral

Started with a recruiter call, then a 2-hour timed take home test which had a 30 min questionnaire too. The virtual on-site was a 45 min behavioral chat, then two 1-hour technical interviews. The technical part felt a bit messy compared to the take home. One interviewer was all about Time and Space complexity, the other said they don't care about it, claiming it's just for interviews. This was weird since the take home test felt very relevant to the actual job. Still, everyone was really nice and wanted to help with the coding problems. The company culture seemed awesome and their communication was top-notch.

Technical Coding

Great company but I didn't do too well on the algorithm question. Would love to try again if an opportunity arises. There were 2 different interview questions, an API and an algorithm question.

Coding Technical System Design Behavioral

I applied through a referral. First, there was a tech screen. They took over a week to respond. After that, there were 3 more rounds: one technical, one behavioral, and one system design. Things seemed to go well in all rounds, but a week later, they said they were seeking someone more senior. I think with all the recent layoffs and a lot of skilled people looking for jobs, companies have more options and their expectations are way too high now. My advice for a Senior role: have super convincing answers for behavioral questions. Mine seemed good, but it wasn't enough. Also, the hiring manager for my behavioral round was really rude, kept cutting me off and yawning the whole time. I might reapply later, but definitely not for that hiring manager's team.
