I started with a phone screen that went well. The recruiter was kind and professional.

However, the person facilitating one of my live coding interviews was rude, entitled, and unforgiving during a complete crash and malfunction of the platform, despite my ability to quickly recover.

Their engineers are almost all (~90%) males from privileged backgrounds. I felt unwelcome and unheard.

If you sense any red flags, acknowledge them, and don't feel bad if you don't get an offer because, from what I gathered, their culture is toxic.

For front-end, practice React.

For back-end, practice using the API framework you know best.
