The process started with a 90-minute OA, featuring two coding problems focused on array transformations and graph traversal. The difficulty was standard, but the format felt similar to Hack2Hire’s timed environments.

Afterward, there were two rounds of technical interviews:

• One focused on a deep dive into interval merging with edge case coverage.
• The other covered basic system design, specifically cache and rate-limiting.

One interview had an engineer who joined 10 minutes late and remained silent until the end. Another interviewer was more open about the current team reshuffling.

After passing all rounds, I was informed there wasn’t a team match, which aligned with what I’d been hearing on Blind and 1point3acres. It appears many are progressing through the process only to be left in limbo.

This experience offers a good preparation opportunity if you are practicing live interviews, but do not count on a guaranteed outcome.

Write a function that merges overlapping time intervals, similar to calendar bookings. The challenge was making it efficient and handling unsorted inputs.
