The process is quite straightforward (although somewhat delayed, about a month): you start filling up a form on the company's website, take a technical test, and, if you pass, record a three-minute video talking about yourself, your background, and the reason you think you're the right candidate.
Once someone from HR reviews your application, they will schedule an online meeting just to review the position, tasks, and salary.
The final step is an interview with a company engineer to solve a task, doing a live coding session (ChatGPT or any other help is prohibited), and later, with the client (since they work as contractors).
