Software Developer Interview at Gitlab

Have anyone recently interviewed for Gitlab for a backend engineer role? How's the process look like? Gitlab seems to be heavily invested in ruby on Rails. Should I even consider ruby to add in my tech stack? I see very few industries still use ruby and virtually not a lot of resources or tutorial focused on ruby compared to python/Java/.Net. Looking for suggestions! TC: 🥜 YOE: 5+ #software #engineering #swe #gitlab
