After applying for a role, I've got a response from their technical recruiter (almost at the next day). At this mail, I received the link for a task to create an API service with provided requirements. In 1 week after that, I received another mail from their recruiter, asking me about my progress in solving task, so it looked like they are interested in recruitment process.
This technical task was not hard, but it required a plenty of configuration for an application, additionally it was just a lot of trivial code, so I was waiting for any kind of a feedback, since I've spent my time on that. Next day I received a confirmation mail that they received my solution and they will review that as soon as possible.
In 2 weeks I wrote a mail that I would appreciate any kind of a feedback. And I had no response on that. 2 more weeks after that I've sent a second mail about my feelings on their recruitment process, and they answered me with a mail, that they are sorry for the delay, and review is still in progress.
Right now it is month and a half (and 2 weeks after their last mail), since I've sent my solution for this position in Freeletics, Senior Ruby developer, and I still have no response.
