Form3 Senior Software Engineer interview questions

The interview process at Form3 was great, my best experience to day, the interviewers were very nice and knowledgeable. It was a three step interview process, the first one was a screening call with their talent team. The recruiter was very knowledgeable and gave me valuable information to prepare for the next steps. Step two was a take-home exercise of writing a client library for their fake account API. I had no prior knowledge of Go before starting the interview process so this step was quite time consuming for me but also alot of fun. Step three was an interview with engineers on the team. The call was divided into three parts, the first one was a presentation of their tech stack and a review of my exercise submission. The interviewee gave me feedback on my exercise and we talked through improvements points, much like what I would expect from a code review. In the second part I was asked questions about the fundamentals of networking (TCP/IP, TLS, Http). The third part simulated being on-call and responding to a system failure. The architecture was described to me and I had to identify where the problem was occuring and how to fix it. Overall the best interview process I've had so far. It's quite time consuming and the expectations are high but it ensures you will work with like-minded and skilled people. I got an offer that was higher than my expectations at the end of the process, which I accepted.

The hiring loop has three steps: - first I talked to the talent partner in form3. Super nice person, we connected instantly and I knew that this was the culture I was looking for. She was super open, answered every question I had, and explained the process in detail. - then there's the take home exercise. While it's not a crazy algorithms challenge, it is detailed work. They give you no deadline to complete it by. It's entirely up to the candidate to decide when to submit the solution. We all know life can be crazy at times, so I appreciate this flexibility on their end. - the final step is the technical interview itself. It's a three parts interview, each with a different engineer. First there's a review of the take home exercise, very friendly. Then there was a more theoretical part including questions about networking, TCP/IP protocol, cloud computing, etc. And finally there's a sort of role playing in which you are asked to answer an on-call page. The technical interview sounds a lot scarier than it actually is. The talent partner made sure to explain every detail of it to me. I had a few days to prepare, and the interview was exactly as I'd been told it would be.
