Canadian Nuclear Laboratories Research Scientist interview questions

I had three rounds of interviews with them all of which were online. First, I talked to HR about 40 min, most of which she was explaining about the company the location (Chalk River). After a week, I had an interview with the hiring manager and 3 of her team members, followed by a 30 min presentation on my research to a large group of employees. The interview with the hiring manager and her team was not smooth at all because the two of them could barely speak English. I had to explain my answers, again and again, multiple times. After 2-3 weeks, I had to follow up with them for the next round. Anyways, I got another round of interviews during which two of the team members, showed me the working environment, their lab, and pilots through MS Teams. After about 2 weeks, I got an email from them telling me my background does not fit the role!

long, detailed, but interactive. i recived some feedback in the end when i asked for it was panel interview and the managers were all nice and i felt a strong connection with them
