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.
Interview questions [1]
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. The process took 4 weeks. I interviewed at Cast.AI in Jun 2026
Interview
The Process:
The process consisted of a recruiter screen followed by 5 separate interview rounds. Despite progressing through the entire pipeline, the final rejection was based on feedback from the very first round, making the extensive multi-week time commitment feel highly inefficient.
The Experience:
The initial technical screening lacked professional courtesy, with the interviewer frequently cutting me off and appearing disengaged.
Most concerning, however, was the cultural fit interview with the VP. The VP explicitly stated that 25% of new hires are let go within the first 3 months. Hearing a C-level executive highlight such a high turnover rate as a point of pride suggests a volatile work environment. Additionally, executive leadership heavily emphasized a hierarchy based on "employee number" onboarding sequence, which signaled a rigid, exclusionary senior management culture.

Question 1
System design was based on what they're building so be sure to read their docs (they're quite good) and understand which team you're applying for.
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.

Question 1
They asked make a design on board exactly what are they doing. Expecting to me say some tricky words.
