I initially applied for the role in early March, but it took about a month before the Recruiter Screening interview was scheduled. Initial screening interview was fairly easy and straightforward and they opted to move me on to the Hiring Manager interview. That took place about 3 weeks later, and again was more of a standard "get to know you" set of questions to determine my qualifications for the role. The hiring manager actually pivoted during this discussion and brought up a new role they were having trouble hiring for internally, and from that point forward the focus was on this new role.
The next step was to complete a take home assignment, where I was to put together a presentation describing my framework and approach to this new role. They provided a very detailed overview of the request, including considerations and examples of the types of problems I would be asked to address. They requested I spend no more than 6 hours on the assignment.
After submitting my take home assignment, Twilio reviewed and then reached out to invite me to the final round of interviews. This final round consisted of 3 40-minute interviews with the Director/head of various Product teams, a 40-minute panel interview with various VP and Director-level interviewers of my take home presentation, a 45-minute interview with one of Twilio's "Bar Raisers" (cultural fit interview), and finally a wrap up with the Hiring Manager. All interviews were scheduled over the course of a week.
Upon completion of the interview process, it took Twilio about 2 weeks to make a decision and send out an offer letter, which I accepted after some back-and-forth.
