Instrumentation Laboratory interview questions

The interview process is quite efficient and straightforward. The hiring manager reached out to me directly and we scheduled a call within a week. The questions were related to the position. A few weeks after the interview, I received the offer.

HR screen (about 30 min) - Phone call 1 hour with the hiring manager - Over Zoom 4 hour interview with 8 people (30 min each) - On zoom over two days The HR guy was very aggressive in getting the interview done. But radio silence after. They claim to due a lot of hiring but I never heard back from them.
