After the application, I was contacted by the HR and given a task to be performed on my own and to submit the source code. I had a few questions about the task which they never answered at all. I was a bit surprised but nevertheless, I completed the task and submitted it. It took me about 3 days to get the job done as it was a new API. After my submission, I was met with radio silence. There was no acknowledgement, not even that they had received my task and were reviewing it. It has been about a month now and I have not received any information. The position is still open.
