The process is quite weird and seems not very friendly. Fair to say, that they have a lot of information and details regarding their hiring process, including what they ask during the interview and things like that. I was contacted by their HR guy and after a short talk he gave me a home assignment right away. Also, worth mentioning that he never cared or bothered to follow up with me if I'm doing the assignment or not and how it is going. They have good options for the home test assignment: you can create one for them, you can show an open source you worked on or you can show them some assignment you made for other company. That's the first time I can see options like that, which is on a good side of their process. Anyway, I didn't have much time, so I took the assignment I made for another company, improved it in several areas and then sent to them. The HR guy replied that he took a look (HR guy reviewing dev tasks instead of the team?!) and it is a low quality, not up to their standard and quite poor for the senior level they have in their company. Firstly, I find it quite rude and unprofessional to say things like that. You can say the same in a different manner - much more polite - and at least give some feedback what exactly is "poor" or "low" for those great standards they have. Otherwise, you just being an arrogant ashl. Secondly, the same very task I committed before to another pretty great company with good reputation and they found it well made and accepted with no problems. And I even improved it after that for Babylon before giving them. Anyway, my experience is quite negative thanks to this HR guy attitude and approach. I wouldn't recommend to deal with them unless you already have some task you made for another company that you can just submit to them as well and not spend much of your time.

There are lots of stages in this process so it ends up being very time consuming for the interviewee. Felt like you were asked some of the questions just because: you answer the question and that's it, no real conversation develops.
