Applied online through Glassdoor. Was contacted by the first recruiter who discussed the interview process and provided information on the company. Was contacted again after around 2 weeks by another recruiter who asked for slots for telephonic interview, which I promptly provided. I was later informed of the date of the telephonic interview for which I promptly confirmed my availability. A day before the interview, I was informed that the interviewer is not available and was asked about other available timeslots, which I again promptly provided. I then got confirmation of the telephonic interview being rescheduled to another date based on the new timeslots I provided. On the day of the interview, the interviewer didn't call me at the specified time and was late by around 10 minutes, as far as I remember. Though the telephonic interview went well and I answered confidently, I was informed (and that too only after I enquired about the result) that I hadn't cleared the round. As the interview had gone well and I was somewhat surprised by the outcome, I politely enquired about some additional feedback for my improvement, but there was no response or acknowledgement from the recruiter whatsoever to my query. Though Twilio's product and tech stack seemed interesting, due to the recruiters lack of follow-up and response post my interview, the fact that the interviewer cancelled the interview once and then ended up being late for the rescheduled phone interview, overall the interview process was a disappointment.
