Yeah, I agree about HackerRank's UI. When I was using it I think I just used PyCharm and then cut & pasted my solutions.
Download them and run them from PyCharm?
I just don't like HackerRank.
Let me rephrase that.
As I grow in my role, I see writing the type of code that can be tested on HackerRank less and less, so investing time in learning how HackerRank works is absolutely not on my radar.
... and getting a HackerRank solution in within that ticking timer absolutely requires me to be comfortable with the HackerRank UI.
So stalemate there.
