Received a response pretty quickly after applying and scheduled an interview a couple weeks from that time. The first interview is technical, and it is a straight hour of coding/coding concept questions in C++ and C. There was barely any talk of background or resume, and only a couple minutes to ask questions.
It didn't really feel like a natural conversation, and was more reading questions off a piece of paper, with no real opportunity for collaboration or working through a problem by explaining your thought process. Seemed like they wanted to get through all of the questions and that's about it.
After that interview, there is another 2 hour technical interview, which I didn't make it to. Overall, doesn't really seem worth it considering the barely "hybrid" work, salary, and type of job to go through that many technical interviews.
