Average Negative Colombia

My process was short and it consisted of two interviews. The first was mainly about my working experience, and the second focused on specific questions about how I handled situations at work.

The interviewer didn’t seem very interested in my answers, and I got the impression the interview was being run out of commitment rather than curiosity. It would have been easier if they’d just told me early that they weren’t moving forward, because I ended up waiting about two weeks for a result that came as a generic email with no feedback.

Remote

I attended a virtual onsite experience tied to Twilio’s engineering organization, specifically with a backend focus—one note mentioned the segmentation team and another referenced platform engineering backend. The common thread was that it was an onsite-style technical evaluation rather than a single screen.

With the details available, I couldn’t reliably piece together the exact round-by-round format or what each interviewer asked. Still, the feeling was that it was meant to be a deeper dive into backend work.
