MKS Instruments interview questions

One phone screen, two teams meetings with manager and his boss, then on site visit for a walk through. After that offer was given by scheduling another teams call for a verbal offer followed by email packet

I thought it was just an interview screen, but the non-technical interviewer asked technical questions about Assembly commands and some OOP concepts. It was the first round so it was just a screen on zoom, IIRC. Zoom screen and then I talked a little bit about myself, then the interviewer went straight into technical questions.
