I was rejected after the first interview, a "pair programming". It was run by a manager, and they intended me to code a simple function in Java on a Google Docs. I offered to do it on my local IDE and share my screen which was accepted. I was not given any feedback at all as to why I was rejected.

Entrevista
After applying online, I had a 20 minutes talk with a recruiter (which I thought was fine, I usually pass this level). He explained about the next steps, but I never heard from them again. Not even a generic rejection email.
