1.) Recruiter inbound message via LI leading to phone screen w/recruiter - basic screen, friendly and informative. C1 is wide open in terms of what you want to do, specific tech stack exp is less important vs. overall engineering proficiency 2.) Online code assessment assignment - 2 coding questions through HackerRank, give you plenty of time to complete them in whichever language you prefer - Can't disclose but they're equivalent to LC Mediums 3.) Live 4hr virtual zoom interview (1 coding, 1 arch system design, 1 behavioral, and 1 code analysis exercise) - large emphasis on arch expertise (i.e. scaling, fault-tolerance, etc.), culture fit, and reasoning 4.) After "recommendation" you meet with several engineering managers where they pitch their teams and initiatives to you to determine mutual fit Overall, it was a lengthy process (took several weeks to complete), but it was one of the best interview processes I've been apart of. I actually felt like I was involved in the hiring process and that C1 interviewers didn't just search some generic/trivial LC problems to work on.
