Wolfram Research Software Engineer - Web Applications interview questions

Applied through my university career website, got an email to setup a screening interview with recruiter. I was asked the tell me about yourself and why Wolfram question, then she just went over the logistics of the position such as salary and location. After a couple days got an email from recruiter to setup a video interview with a Software Engineer. I wasn't prepared for the interview I think I answered around 75% of the questions right and of-course got a rejection letter after the interview. I was asked basic java questions and then transitioned into JS questions towards the end. The SWE who interviewed me was rude when I asked questions about the role and implied I should have done my research about the role. She also had her camera off so I couldn't see her in my video interview, but I was requested to keep my camera on.
