Pretty much what you see here. 3 hour API test - this was a lot of fun. Some advice for this would be to have your dev environment set up. You know you'll be consuming an API so have a project ready to go for this. Get it working first, then tidy up the code. Once you get it working you can use the time remaining to tidy up the code. After that, I had a 4.5 hour onsite. This was where I made the decision that I'd love to work here. Everybody that I spoke to was easy to get along with and they seemed passionate and humble. For a frontend job: get up to speed on ES6, read Javascript: the good parts and cracking the coding interview. The interviews are not difficult if you prepare well for them. They clearly care a lot about hiring and this shows in their hiring process. The recruiter was always very transparent and communicative. I'd highly recommend applying.
