Once I got matched, we first had intro call, this was a get to know each other type of set up.
After that there was another call with the Co-Founder, here we went through the general what was expected of me, how will I be contributing, how my career will shape and what all be expected of it.
Then we had a technical deepdive round, this was one of the system and API design round which meant going and designing the system for a given problem, considering all the catches and things around it.
Then was the final round of take home assignment. One of the co-founder specially designed an assignment considering my background, and was given almost a week to submit it.
