Revolut Software Engineer, Backend interview questions

The interview process was a bit weird, I was contacted via LinkedIn and they seemed insistent on having a video call. Which I accepted, however the interview was scheduled with a different person, which I found strange, but nevertheless we had a 30 minute interview, it didn't go so well, partially because although I am familiar with concepts like Big O notation, SOLID and ACID, I learned about them in college and in my native language, I understand them, but it's not that easy for me to tell you what each letter means, in my opinion, it would be more interesting to have examples of bad code/practices and then asking why they weren't good practices. The most strange part in all of this was that they did not ask for my CV once, and they seemed really fixated on a couple of points and didn't trying to give me a space to talk about myself and what I could have to offer. Not that bad overall, but it did feel like instead of an interview they should just send a quizz where we can check certain points.
