Screening interview (30 mins) followed by technical interview (1 h). Screening interview was standard, relaxed and casual. Technical interview felt more like an interrogation, the founder was like a dog with a bone with each question. I think the problem here was the difference in academic backgrounds. As my work requires a lot of different techniques, I'm not an expert on the in depth theory of how each bit of equipment works (who is?!) and I think this is what the founder was looking for. Personally, I did not enjoy my experience of the interview process and had already decided I didn't want to work there based on the atmosphere of the technical interview. I did, of course, still want feedback so that I could use it with future interviews. However, even after two follow up emails, there has been radio silence from them.
