Applied on their website with CV, motivational letter and trivial tech question. After that you are given a full day technical challenge that you need to finish within a week. Technical challenge was to implement an app that tracks your location in the background and pulls photos from FlickrAPI. As I can see from other reviews, it's not only me who got the same problems with them, so be careful - don't waste your time with this company Challenge itself is okay, but apparently they are more interested in the quality of Flickr API than your coding skills. I was rejected from proceeding because "We were getting a lot of the same photos", while feedback about my code was positive. Also HR clearly used wrong template to inform me about all of this - the email was saying that they enjoyed "meeting face to face" and "thoroughly talking", even though it didn't even get to it. Overall negative experience
