I was told there would be a general technical interview and to study web development. I studied a ton of web development, but it turned out the technical interview was actually a VR interview. This caught me off guard, since I had prepared web technologies. I still did okay on the VR questions.

After passing the technical interview, I entered project matching, where a hiring manager for a project saw me and wanted to interview me. I interviewed with him to discuss design, projects, and general interests. I was later informed that the hiring manager wanted to extend me an offer to work on his project for the summer.

I don't want to share specifics, but they asked about my design process.

There was also a VR development question.

I assume it's similar for web prototypers as well.
