Full Experience
Hi Folks, I recently completed Twilio’s interview process for the Software Developer (L1) position. The process began when a Twilio recruiter contacted me via LinkedIn about the opportunity. The following day, I had a recruiter screening call over Zoom, where we discussed my current work experience, and the recruiter provided details about the role and the interview process.
Interview Process
Round 1: Coding/DSA This round involved two questions that I had to solve in 45 minutes. The first problem was to find duplicates in an array, and the second was to reorder a linked list.
Round 2: System Design (HLD) For this round, I was asked to design an audit system for e-commerce platforms, with a focus on the data aspect. By the end of the interview, I was able to present a complete and functional design. Additionally, the interviewer asked a scenario-based question related to Twilio’s MAGIC values, assessing my alignment with the company’s core principles.
After successfully clearing both rounds, I was invited to the final hiring manager round.
Round 3: Hiring Manager The conversation started with introductions and a discussion of my current experience, followed by some behavioral and scenario-based questions. I found the hiring manager very approachable and easy to talk to.
Result: Selected Overall, Twilio’s interview process was smooth and transparent, with clear communication throughout. I had a great experience interviewing with Twilio, and I'm pleased to share that I was selected for the position.
