Add a timer feature for user's to see how long it took them to solve a problem, and show them the recommend time to solve during an interview.
Timer depends on the problem:
Easy problems: 10-15 minutes
Medium problems: 25-30 minutes
Hard problems: 45- 1 hour
(not sure if these times are accurate, but from my experience it's what it feels like) you guys can help decide these timers.
