Out of interest, could you give us a rough idea of the scope of a 2-hour take home exercise for a front end position?

Not the OP but I've given these so I'll answer.

Given a provided mockup of a react component implement it to the best of your ability. In my case it was a stopwatch (which has non-obvious edge cases in javascript) with some curvy UI that's tricky to do in CSS.
