It was a competition where we had to code a certain set of tasks in the allotted time, it was fun! It was then followed by a quick interview. They reviewed my code and assessed my interview, called me then emailed my offer.

They didn't even interview you at the beginning, they just sent me a task that took 4 days to finish and when I finished it and pushed the code to Github, and added their email as a contributor, they didn't even accept the invitation which means they didn't look at my look. so I don't know how I should call this, but this seems to be a sense of unprofessionalism and unappreciation.
