Twilio Staff Software Engineer interview questions

Really good communication and very friendly. All conducted via zoom as was for a remote position. Lots of documentation on the interview process provided up front. Overall, a very professional and friendly process - even if I wasn't successful!

1. Introductory communication from the recruiter. 2. Coding test on HackerRank (fairly easy). 3. Four 45-minute interviews with: a.) Hiring manager (he did most of the talking) b.) Design problem on a virtual whiteboard - the problem wasn't difficult (a system received 1K events/second, which need to be fed to a black-box ML system once per hour and certain actions need to be taken based on the output of that). The interviewer was a bit antagonistic, which I wasn't expecting. c.) Another coding test on HackerRank. This one was more domain-specific, but still not too difficult. I've forgotten the problem, but it required implementing sliding windows. d.) A bar-raiser, who asked behavioral questions.
