Ok.. So I applied for a web dev position at a small-to-medium sized company. They had a telephonic round which they were happy with. They then sent out an assignment for me (A simple webapp to complete in 1hr). I did it and sent them the code. Finally, the face to face interview also went well.

At the end of it all, the HR comes back and tells me - "You did not use a MVC framework for the assignment and your code was not optimized for unit testing."

Me - "Ugh. (1) You did not have to call me for the face to face interview if you did not like my code. (2) You specified NOT to use any 3rd party libraries when doing the assignment. (3) You can tell people directly that you cannot afford them."
