Behavioral Technical System Design Coding Technical
The whole thing started with a recruiter chat about the job and my background. Then I had a system architecture chat with someone on the team. After that, I interviewed with the hiring manager. Next up was a live coding session with the hiring manager and another team member. I also had to do a programming exercise as a take-home task. Then I walked through the take-home assignment with the hiring manager and a teammate. Finally, I had to give them 2-3 references. It was all online, and they let me know the whole plan pretty much from the start, which was cool. They sent clear info before each step about what to expect and if I needed to prep anything, like getting a dev environment ready. They were good at keeping in touch, usually getting back to me within a few days after each stage, and scheduling was easy – I just gave them my availability and they set it up. The interviewers were nice and professional. I got a good feel for the job and what they’re looking for. It was also great to meet some of the team members during the interviews; it gave me a better sense of who I might be working with. It did take a good chunk of time, a couple of months overall, with about 1-2 weeks between each round, but it felt well-planned and was a good experience.

Coding
I took a 30-minute CodeSignal Assessment. It felt way too fast to actually pay attention and implement properly. The question wasn't too crazy, but the time limit seemed too short to really prove any skills.
Confirmed questions1 question
- Can you explain how to assign server numbers when new server requests come in, making sure allocation and deallocation are efficient, and handling different server types with their own number sets?

Coding System Design Behavioral
The interview process felt pretty standard, basically like doing parts of the job. The technical questions weren't super hard, but they really care about understanding the whole coding process. Like, why you chose to do something a certain way, how efficient your code is (both time and space), and making sure you handle inputs correctly. It's less about getting the perfect answer and more about showing them how you think through the problem. On the behavioral side, they asked some interesting questions, like what you like and don't like about your current job. They also asked about times you disagreed with people and sorted it out, or a project you were really proud of. They were also curious about your hobbies and how you got into them, because they want people who are into stuff outside of just coding and have a wider view on things.
Confirmed questions3 questions
- Can you write code to get a specific page of data from a paginated API, given the page size and index?
- Starting with two given non-negative integers, can you generate the next 10 numbers in the Fibonacci sequence?
- How would you design a system to rate-limit users to 500 requests every 10 minutes for an API that runs on auto-scaling EC2 instances?
