Started with a standard phone screen, non technical and just making sure you're an okay person. Following that, you go in for a 1hr programming test where you get to choose from 3 challenges and code one of them in java. Coding a data structure, basic client server interaction over network, a game, basic encryption decryption are all possible challenges - with the expectation that you may not finish. Good coding practice is important. Next was brought in for an in-person with cofounder and a lead developer. The interview was entirely technical, about 2 hours, with no questions asked about myself. Questions focused more on my understanding of databases, networks, low level code execution, garbage collection, data structures, rather than my ability to code any algorithms, although it probably depends on who interviews you. I could have done better so I have no problems with not being extended an offer, but I had a great impression of this company beforehand yet despite communications from me just asking for an update after the in person interview, I was simply ignored and left hanging. Seems like a great company outwardly and they may well be, but expect to be treated as an afterthought if you are a candidate who has not passed their standards. Move on after the interview.

Applied online and had a generic phone interview followed by scheduling an onsite coding challenge. The coding challenge was a Connect 4 disk game in Java that also had simple AI where it just did a random move and they expected you to complete it in an hour without any internet access on their laptop. They themselves have mentioned that they don't expect it to be finished and that they look at the architecture more but that's bull since they do actually expect everything to be done. If you get an interview with this company and want to succeed it, do whatever it takes to ensure that you can code Connect Four in an hour, whatever it takes.
