California City, CAPosted Jun 2026 · Candidate report, summarized by Dataford

My process started with an online coding assessment that ended up feeling brutal mostly because of how the tool environment constrained what I could do.

The whole thing took about 70 minutes. It opened with seven multiple-choice questions that weren’t too bad, then moved into a LeetCode-style medium problem, and finally two ML-oriented coding problems that required building from scratch.

The weirdest part was how much time I lost just fighting the interface and constraints during that coding section. Even though I could follow the intent of the tasks, getting the implementation to work smoothly took me longer than I expected, and by the time I hit the tougher parts I felt like I was reacting to the tool rather than solving the problem
