Based on 4 reported problems, Pony.ai interviews are slightly harder than average - 25% Hard vs 18% across all companies. The majority (75%) of questions are Medium difficulty, which is typical for companies that want to see solid fundamentals without excessive trick questions.
Compared to the industry average, Pony.ai puts unusual emphasis on binary-search (75% of problems, 8.5x the industry average), greedy (50% of problems, 5.8x the industry average), sorting (75% of problems, 5.1x the industry average). If you're short on time, these are the categories to double down on.
The most common topics are array (100%), binary-search (75%), sorting (75%), dynamic-programming (50%). Problems below are sorted by frequency, the ones at the top are asked most often.

Pony.ai interviews focus heavily on array, binary-search, sorting 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. Pony.ai interviewers care about your thought process - how you break down a problem, consider edge cases, and evaluate tradeoffs between solutions. A clean O(n) solution you can explain clearly beats an O(log n) solution you can't articulate.
