35-question written interview followed by a technical test. The questionnaire is very time-consuming, and took me nearly 4 hours to complete. I was under-prepared for the technical test, in hindsight the questions were not difficult.

Question 1
For Software Architecture, expect system design questions, how you think about distributed systems, trade-offs in architecture decisions. Linux system skills - should have clear Linux knowledge: Kernel and shell - description, Foo.sh permission denied error when running (./foo.sh) what to do to fix it, How ssh works, Container and VM - difference, OpenStack
The interview process included four stages: an initial phone screen with a recruiter, a technical phone interview covering Python fundamentals and algorithms, a live pair-programming session on a real-world task, and a final interview focused on system design and team fit. Each step lasted between 45 and 60 minutes. The interviewers asked for explanations of tradeoffs and for code clarity.
