N26 Java Software Engineer interview questions

At initial stage, means recruiting agency screening was quote good - I’ve converted with polite professional requiters about common topics. Next, my contact was given to N26 recruiter, she was polite and nice person too. As a first stage here I got a task to do some programming exercise, nothing serious, I’ve asked how much time it takes average candidate to finish it, the answer was - 3 hours. Ok, it took me 9 hours just to implement basic requirements of the task (it took me whole weekend). Anyway I’ve passed this stage successfully, and next stage was one-to-one Skype conversation, with a common questions. After that I got an email that I am rejected. Ok, no drama, I’ve asked for feedback, but got nothing, complete ignore from recruiter, who before was 100% responsive and available by skype, but after reject I got - simply no answer. Can’t consider this as decent behaviour as possible employer. If you’d like to waste a weekend and get nothing in return - this company for you.
