Based on 4 reported problems, Niantic interviews are easier than average - only 0% Hard compared to 18% across all companies. The majority (100%) 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, Niantic puts unusual emphasis on hash-table (50% of problems, 2.2x the industry average), string (50% of problems, 1.8x the industry average). If you're short on time, these are the categories to double down on.
The most common topics are string (50%), array (50%), hash-table (50%), sorting (25%). Problems below are sorted by frequency, the ones at the top are asked most often.

Niantic interviews focus heavily on string, array, hash-table 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. Niantic 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.
