It took 1 week. First initial call with HR then coding challenge. After couple of days i got negative feedback from developer saying my app doesn't work. That was really lazy move from developer who didn't even have time to have a proper look on app. All requirements were met but seems like the hiring developers are not having enough patience to have a proper look. After that i send the video showing that app is doing what was supposed to do and made all remarks regarding the requirements itself but that wasn't enough. I have more than 8 years experience with development and hiring and i never had bad experience with any company.
