It was pretty chill process, first interview with program manager/hr and some technical questions to understand your background, second interview - more about system design and software engineering in general, they wanted someone who has experience with k8s, third interview is a coding challenge, I would say its not hard, but its not a general "leet code" style question, its a problem where you need to implement solution, if you know GO and system design you will pass it. I think I have not enough experience with k8s and made 1 mistake on coding section, so they decided not to continue. But I liked the process overall. And since they are basically a company who builds stuff with k8s u need to know internals and some gotchas.
Overall positive experience.
