I applied online. The process took 4 weeks. I interviewed at Twilio (Madrid) in Sep 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.

Question 1
System design: "Design a photo upload/album printing application"
It was whole day interview from 9 to 5. Each hour new team interviewed me with new design problem. The last one was with HR and on my answer about salary expectations, she reasked and said they need to think. I did not got offer.
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.
