Behavioral Technical System Design
First there was a screening call where we talked about my past experiences and they asked some tricky questions to see if I was ready for the technical interview. The next interview was a technical system design interview. They wanted me to design their system. I didn't think it was fair because they've been working on their design for a long time to make it work, and they expected me to come up with a similar design in just one hour.
Confirmed questions1 question
- Can you make a design on board that is exactly what they are doing? Expecting me to say some tricky words.

Technical System Design Coding
The interview process was pretty chill. First, there was an interview with a program manager/HR where they asked some technical questions to understand my background. The second interview focused more on system design and software engineering in general, and they specifically wanted to know about my experience with k8s. The third interview was a coding challenge. I'd say it wasn't too hard, but it wasn't a typical 'leet code' style question; it was more about implementing a solution to a problem. Knowing GO and system design would help pass it. I think I didn't have enough experience with k8s and made one mistake in the coding section, which is why they decided not to move forward. I liked the process overall, though. Since they build stuff with k8s, knowing its internals and some gotchas is crucial. Overall, it was a positive experience.
Confirmed questions4 questions
- Can you elaborate on Kubernetes and its inner workings?
- What are some common pitfalls or advanced concepts in Kubernetes?
- Questions about system design, covering aspects like availability, scalability, fault tolerance, and monitoring.
