It was good. They only asked about my resume and asked to explain all my projects and my contribution in them. That was it. It was pretty basic. Not that hectic.
I reached out to the research scientist and talk about my projects that align with him. Then we set up a call to further discuss about it. Then he set up an official meeting with other scientist in the team to discuss more about the alignment between company and my project.
1 hour online meeting with a research engineer. Talked about resume for about 15 minutes and then a few behavior questions for about 40 minutes. Not many technical questions asked.
