I had a horrible and completely time-wasting experience with their hiring process. I passed the initial interview, the online test and the online coding session. At the last step I was given a project to finish in two weeks which in real-life would take months multiple developers. Having a full-time job, I spared my next week for this task and scheduled the last interview to 1 week later. Somehow their "system" messed up and they made me reschedule it for some other time. Considering that I could not spend any more time for the project, I chose the earliest possible time. The last interviewer disregarded my efforts completely, expecting a production-level, fully-functioning project after a single week. It was my problem that I didn't have the luxury to spend two full weeks for their project. Their interview is not just difficut, they try to have their candidates work for them for unreasonable amount of time.
