1. Screening
Why BlockFi? What are you looking for in a job at this time? The recruiter was extremely nice, he was candid when talking about how the culture of the company is evolving as they grow.
2. Technical interview:
Basic Elixir and OTP questions ("what's the pipe operator for?", "what are BEAM processes useful for?") and as the interview progressed, system design ones (caching, API rate-limiting, handling load spikes, error mitigation in production and designing for limits in external providers).
3. They decided to stop the process before the chronological interview.
