Coding Technical

I was approached by a recruiter at Radix and went through 3 interview rounds. The first was a coding challenge that was tougher than typical LeetCode problems, requiring detailed problem decomposition, case analysis, and interface definition. The last interview involved a technical discussion with a Senior Engineering Lead who focused heavily on git internals for about 30 minutes. I mentioned I understood git well generally but hadn't deeply studied its implementation. Despite this, I attempted to reason through its workings. While the lead was not rude and I learned something, I was later rejected because they specifically sought someone with deep git internals knowledge, something not previously communicated. This felt like a waste of time as they should target candidates with that specific expertise.

Technical Behavioral

I had an initial one-on-one interview near my school. It included two technical questions and a chat about my interest in the company. Later, I had an on-site interview day a few months after. Several candidates and Radix employees, including the founders, were present. We candidates rotated through interviews with the employees, each lasting an hour. In total, I saw 5 interviewers. There was also a one-hour break for a free lunch. Each interview was quite relaxed, with maybe one or two technical questions from the interviewer, and discussions about their work at Radix and the company culture.

I did an on-campus interview where I got a programming problem about moving averages. After passing that, I was invited to Chicago for a super-day. The office was really nice and they fed us. During the super-day, I had 5 interviews with most of the people in the office.

I got a 15 minute recruiter screen. It was mostly just introducing myself and then some follow up questions. They also gave a summary of Radix's data pipeline infra and the team, and I had some time for questions. After that, they asked me to forward my resume to the hiring lead, but I didn't even get past the resume screen.
