It was online. The interview was very professional but relaxed. There were two interviewers. It lasted about half an hour. It took 4 business days to get a response. I would happily interview with them again.

Two-round interview process: Prescreening (15–30 mins): brief phone/video to confirm experience, fit, availability, salary expectations, and basic problem-solving. Practical test interview (60–90 mins): live coding or take-home task with walkthrough to evaluate technical skills, testing, optimization, problem-solving approach, and communication; ends with feedback and next steps.
