StreamWIDE Android Engineer interview questions

First on site interview: General resume and relevant experience questions. After that, they give you a home assessment to complete in the next 7 days. You're asked to implement a solution. In my case they asked to implement a solution in which you import any kind of files into the apps internal storage. the files have to be encrypted and decrypted upon preview. They asked me to upload the solution to github. They didn't even accept the invitation so I recheck with them to see if they had any issues accessing the repo and they said: they would have to log in into github in order to see the repo, which was probably too much work for them and asked if I could make the repo public, which I did. I re contacted them and they didn't even bother to reply. completely unprofessional.
