1. Recruiter inbound message via LinkedIn leading to a phone screen with the recruiter. This was a basic, friendly, and informative screen.

For this role, C1 is wide open in terms of what you want to do; specific tech stack experience is less important than overall engineering proficiency.

1. Online code assessment assignment. This involved two coding questions through HackerRank, with plenty of time provided to complete them in whichever language you prefer. While I can't disclose the specific problems, they are equivalent to LeetCode Mediums.

2. Live 4-hour virtual Zoom interview. This included one coding question, one system architecture design question, one behavioral question, and one code analysis exercise. There was a large emphasis on architectural expertise (e.g., scaling, fault tolerance, etc.), culture fit, and reasoning.

3. After a "recommendation," you meet with several engineering managers. They pitch their teams and initiatives to you to determine mutual fit.

Overall, it was a lengthy process, taking several weeks to complete, but it was one of the best interview processes I've been a part of. I actually felt involved in the hiring process, and that C1 interviewers didn't just search for generic/trivial LeetCode problems to work on.
