Quite an awkward meeting with a tech lead (a very prominent HN commenter). I've got quite negative vibes right from the start. My feeling is that either I didn't brag enough about how much I am an awesome-developer-slash-genius, or I simply look too old (~40, which was far more than the interviewer). Although application required documenting open source contributions as well as auxiliary questions, these were not discussed.

Met with HR first then the tech lead of the team I was interviewing for. The questions were more generic rather than too technical. The next round was supposed to be a take home exercise but they cut the process short.
