Zendesk interviews focus heavily on math, greedy, array problems. If you're short on time, these are the categories to prioritize. The problems on this page are sorted by frequency, so start from the top and work your way down.
Beyond solving problems, practice explaining your approach.

A clean O(n) solution you can explain clearly beats an O(log n) solution you can't articulate.
