Based on 2 reported problems, Clari 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, Clari puts unusual emphasis on binary-tree (100% of problems, 20.3x the industry average), tree (100% of problems, 18x the industry average). If you're short on time, these are the categories to double down on.
The most common topics are tree (100%), binary-tree (100%), array (50%), hash-table (50%). Problems below are sorted by frequency, the ones at the top are asked most often.

Clari interviews focus heavily on tree, binary-tree, 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. Clari 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.
