You can very easily apply online e.g. through Linkedin. The response is quick. Firstly you'll talk with the recruiter which is rather usual talk about your past experience, the company style, some common ways of working in the company, and your expectations.
The next round is the Coderbyte challenge with easy/medium algorithm questions and a simple React one. This one doesn't require a lot of preparation despite you getting a huge email with a way to prepare for it.
After there was an application debugging session. The application is pretty simple, a kind of media player with transcription. However, the way it is written is not that straightforward, the folder structure is unclear with many index files containing logic, some overcomplicated usage of styled-component, very specific libraries, etc. Also, you will get a link to CodeSandbox and not the repo to work on. It took me around 5 minutes to make the environment editable for me. I have never used CodeSandbox for debugging purposes and to be honest it's far away from a good environment for that. For future applicants, I would recommend using a separate big monitor to feel more comfortable it was hard to do on a small-screen laptop.
As a result, I wasn't able to build a proper map between the code and the application's view, and in the end, I fixed less than half of the bugs.
Also, I didn't find a flow with the interviewer and we didn't have a nice cooperation during the interview.
