Interview consists from 5 steps:
first one is: TA - very common
Hiring manager (Director of Engineering) - was very cool, and i enjoyed conversations
Tech assessment - I have to do system design as a home work (explain some architectural challenge from my work experience) and present at the interview
PM - smooth, you can get insight of what are company ambitious,
CTO - that was hard, as got few questions that I was not prepared for.
Rather fast, all interviews within 1-2 weeks
