Had an initial chat with the CEO, it felt more of a "Behavioral" kind of interview in which we talked a lot about my past experiences. After that one, the technical interview was just 2 hours of hectic technical questions, related to Kotlin/Spring/Java, it felt like the interviewer was just as tired as me by the end of it. Got completely ghosted after this, no feedback, no-nothing. Overall a very bad experience with them.
