I applied online. The process took 3 weeks. I interviewed at Twilio (Tallinn) in Feb 2020
Interview
Best interview experience I have ever had. I have applied one evening and received a reply the next morning! The process went very quick, even though there were about 6 stages. Twilio Estonia did a great job, from recruiter to the engineers who gave me tech tasks. I felt that I would be welcome in the company so I was happy to accept the offer.
The interview stages included a call with a recruiter, a Hackerrank challenge, then on-site round of interviews on different topics (Architecture, Security, Coding). The selection process is quite thorough but everyone was helpful and friendly when I didn't know something or was stuck at some question.
I was given a take-home coding exercise, which was quite a bit more hefty than most others I've had. Sent a link to the public repo a few days later. The following week, the recruiter asked me to send the link I already sent. When I followed up the next week, I found that the recruiter's email bounced - they were no longer with the company. So I then emailed a higher-up, who passed me along to another recruiter, who I then sent my exercise to yet again. A rejection followed soon after with no feedback.
Phone screen and onsite with a few leetcode and system design questions. The overall process was professional and the recruiters did a good job of keeping me up to date.
