The recruiter contacted me inviting me to participate in the selection process. The first conversation was standard, addressing the position, salary, benefits, etc.

The next step was a technical interview (in English) on CodeSignal, where the interviewer asked me to develop a card game (something similar to Uno). It wasn't an algorithms interview, but rather about data structures and modeling.

I managed to complete all three exercises, and the interviewer gave feedback saying it was very good and that the code was clear. The interviewer, despite having only a few years of experience and having spent a maximum of six months at each company, boasted about having interned for four months at Facebook, with an air of superiority.

After 10 days, I received an automated email saying they would not proceed, with no reason, no feedback, nothing.

Implement a card game where each card from the deck costs X gems of one color, Y gems of another color, and so on. There were 3 incremental exercises.
