1st interview - easier algo 2nd interview - Harder functional programming algo, but whiteboarding it, similar to leetcode champagne tower (functional programming) final - building a state machine while pair programming and discussing differences between popular state machines, talking about scaling in previous companies, a lot of probing behavioral questions by the EM that felt like they were trying to push me into saying I had problems with previous colleagues that I didn't really (I loved my former job I was just moving to a new city)
