A full 9 hours of calls and questions. 1. An initial phone call with a recruiter asking about skills, experience, and expected comp. 2. A 3 hour hacker rank timed exam with 4 questions, 2 computer science and two practical. Anagram problem, KSub Arrays, and two real world easier problems. 3. If you pass the coding challenge a second call with a recruiter prepping you on "The Twilio Magic" and how they interview. They provide a PDF with details of the STAR method. This is where it becomes really obvious that Twilio is a large company with a large HR team. 4. A "Virtual On Site" that lasts 5 hours. Each session is supposed to be 45 minutes but they all go for an hour.

None of the Interview panel is interested in hiring a good team, they seem to be forced to do this except for the bar-raiser. Requirements in the interview are not clearly explained, interviewer did not even ask for my summary, did not explain about his experience and the details regarding the round, he was quick to jump to question and answer within the first 3 mins. With that being said, forget about the help, you are expected to fail and they seem to have made it a point to do so.
