It was a long process. The first two rounds were screening over a telephone call. Then, the second round was a 4-hour interview on Skype, followed by a 5-hour on-site interview.

First, a call from a recruiter. Then, a phone interview with the hiring manager. After that, they paid for travel expenses for an on-site interview, which included five one-on-one interviews with engineers and one behavioral interview with a manager.

The interview provided a well-balanced evaluation by beginning with basic questions about JavaScript's inner workings—covering topics like closures, event loops, and asynchronous behavior—and then transitioning to more advanced inquiries about React.
