I applied online. The process took 1+ week. I interviewed at Hazelcast (Başakşehir) in Sept 2019
Interview
Firstly 30min screen call happened. There are many technical questions in this step. After that if you pass you will take 3 days project to finish. Be careful about unit tests and clean code since I failed because of this. If you ask why I am failed, they are giving constructive feedback
