I applied through an employee referral. The process took 2 weeks. I interviewed at Twilio (San Francisco, CA)
Interview
I was referred by an twilio employee. Initial recruiter call was scheduled which went well, followed by hiring manager call which also went well, at the end of the call I was told I will be receiving an email from recruiter asking for my availability for further technical rounds. And to my surprise I received an automated reject email after a few days. I am totally fine getting one. But not after the HM informed that I would be asked for my availability for technical rounds and move fwd with my application. Totally unprofessional and did not expect this from twilio. I don't want to take the recruiter / HM names out here because unlike twilio I understand professional ethics. All that happened to me was I wasted hrs of my life for this unprofessional attitude company which I am never going to get back. Hope twilio doesn't treat other candidates like this. I would never again interview/work in my life for TWILIO no matter how great they are they have have common sense and a basic sense of accountability and responsibility.
Thank you for your feedback, we appreciate your candor. Your comments are a good reminder for us to always put ourselves in the candidate's shoes and ensure that we place transparent, honest communication at the forefront of all our interactions.
Other Senior Software Engineer interview reviews for Twilio
Three-stage process: recruiter screening, a test task and on-site interview. Both test task and the on-site were simple and straightforward, with focus on practical skills. On-site included the prospective team lead, VP and a team lead from another team in the same location.

I applied online. I interviewed at Twilio in Jan 2025
Interview
Interviewed for the L2 role on the Channels team. I did the online assessment (~3 hours), passed it, then was notified saying they filled the role and were no longer considering me. No referral to another role either. Long story short, don't let this awful company waste your time.
2 algo problems (listed below), 1 easy SQL problem, 1 easy API data retrieval problem, and 2 trivial multiple choice problems.

Question 1
Similar to LC1664 - Ways to Make a Fair Array except you don't need to count the number of ways to make it fair, you just have to find the 1 index to remove to make it fair.
If you google Hackerrank Approximate Matching you can find some material on it. Involves calculating a text score for substrings of a word based on a given prefix and suffix.
I applied online. The process took 4 weeks. I interviewed at Twilio (Madrid) in Sept 2023
Interview
I applied on the website (redirected from LinkedIn) and after a few days I was contacted by the recruitment team and an initial short call was arranged. After this call, I was given a HackerRank test to complete, which consisted of 3 multiple choice questions and 2 coding exercises. My technical assessment was reviewed and I was told that I was approved and the next interviews were scheduled. I then had 3 interviews together (but on different days with different interviewers): Coding, System Design and Behavioural. Note that one interview doesn't eliminate you from the process, but a final result is expected as a combination of all the interviews. A few days after the interviews, I had another call with the recruitment team to get the final feedback, and in my case, unfortunately, the recruiter told me that they wouldn't be proceeding with an offer for me. I would just like to add that everyone was very friendly throughout the process.
