I submitted the coding exercise and haven’t even received a confirmation receipt or any feedback. I spent number of hours doing the coding exercise, an email reply would be nice.

Called and had difficulty understanding who they were or what they wanted at first, after a minute they made themselves clear. Told me they would email a coding challenge to complete, I did not receive it so I figured if they couldn't even email me that it wasn't somewhere I really wanted to work. I received another call the next week and was asked about the coding challenge, I told them I never received it, they did not believe me at first. I provided my email again, they sent it and it came through, I completed it, returned it, never heard back from them.
