First was screening call. Talke about experiences. Also asked some tricky queston for understand am I enough to technical interview or not.
Second one was technical System design interview.
They asked to me design their system. That was not fair IMO, They are working on the mature design long time for to make it working. And they expect me same or almost same design in 1 hour.
Interview questions [1]
Question 1
They asked make a design on board exactly what are they doing. Expecting to me say some tricky words.
I applied online. I interviewed at Cast.AI in Feb 2026
Interview
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.

Question 1
Many questions related to k8s and how it works, system design questions(you need to know availability/scalability/fault tolerance/monitoring etc).
I applied through a recruiter. I interviewed at Cast.AI in Apr 2025
Interview
My meeting was unproductive. The questions, read directly from a prompt, led to a very superficial conversation. The interviewer seemed disengaged, frequently yawning and appearing to be suffering from a hangover. As a result, the questions were unclear, and there was no genuine interaction.
