The interview process had three steps:

1. First, a 45-minute online Triplebyte multiple-choice test. You could choose between backend, frontend, iOS, and Android as the main subject. Each question had a timer and a "don't know" option. The quiz adapted to your strengths, and you could get a perfect score even if you skipped a few questions. The quiz covered CS fundamentals, programming logic, debugging, function naming, SQL, and system design.

2. Next, a 30-minute recruiter chat. I was asked about my background and why I was interested in Coinbase.

3. The final step was a 1-hour technical video interview with a software engineer at Coinbase. I was asked about my background, and the technical problems involved debugging, data structures, and system design.

My recruiter and interviewer were both super nice and friendly, making the whole process very pleasant. My recruiter was also very responsive. The entire process took about four weeks, but would likely have been quicker if Christmas and New Year's hadn't been in the middle of it.

Given some classes, methods, functions, and function calls, edit the code to fix both a programming logic and a design problem so the code runs without errors.
