GitLab Backend Engineer, Defend interview questions

I'd applied online from a job listing found via LinkedIn. The initial application form had a few technical questions. I was then contacted by a technical recruiter from GitLab to set up a time and date for screening call. I was then asked to set up a time and date for a technical interview, and was provided access to a GitLab repository for a Ruby on Rails project, and asked to make comments on anything I saw worthy. Having worked with Ruby for a number of years and with GitLab in my current position, I felt fairly confident going into the interview. However, the role appears to require extensive knowledge of Ruby on Rails, and I was told 20 minutes or so into the interview that unfortunately a strong background in Rails specifically was required for the position. So it looks like I'll be brushing up on Rails before reapplying. Gitlab is a great product and would love to work there one day. Overall, technical interview and recruiters were pleasant and helpful.
