I have kids and I can find 4 hours for an assignment. It's painful but for the right company, I'd do it (I did and I'm glad).

However, if I don't find the ballpark of the salary on Glassdoor, which is information you DON'T control (this is an hint at showing the salary), I won't even consider your company. What's worse than wasting 4 hours and then seeing an offer that's lower than your current pay?
