Got reached out by the recruiter. The first call was a normal recruiter call - mostly background check and expectations match After that technical question-and-answer interview with the senior engineer from the team I think the questions weren't too difficult but the expectations were too high from their side. Maybe they're too early in the process of hiring for this role because the interviewer mentioned that he hasn't got any defined format from the orga so he is just gonna ask random questions. Which tbh, felt like an alignment issue between c-level and engineers. Also, it felt like too much to expect from a candidate what one specific eBPF hook does or so. Like come on, its an open source code, it can be found online if the basics are clear. I also never heard from them after that call. I had to go and check on their job portal to find out the stage of my application. Which personally I think is rude.
