In my experience, it can be a little awkward. At one point I interviewed with a company that uses Rubymine almost exclusively, and I had previously only used Sublime / vim (and Eclipse for Java). It was definitely more distracting than I would have thought going in. Everything is a potential hickup, from tab switching, file navigation and basic shortcuts. It's definitely less than ideal, given that you're essentially context switching into basic operational stuff when what actually matters is the logic of the problem at hand.
