Interview process was multi-stage and thorough. Creating your own trial store was optional in the application, but I would recommend doing so. It will not only show enthusiasm, but will help with 'the Gauntlet' interview if you're successful down the line. I found the two interviews I had with an HR rep and then later a team leader to be pretty standard. Relatively straight forward and normal interview prep will get you through. The Technical ('Gauntlet') interview is more of a work test; 2 concurrent chats and a single phone call with a merchant. If you find the correct info quickly they'll keep adding more to their request to keep the conversation going. My biggest tip is to keep the merchant on the line with phrases like "just hunting for the best way to do that, I'll be right with you", or just general chit chat "what does your business do/where are you based? etc." You're being assessed on how you interact as much as finding the right info. Definitely worth looking through their online help and your trial store to get familiar with it all.
