Based on 5 reported problems, Cloudera interviews are easier than average - only 0% Hard compared to 18% across all companies.
Compared to the industry average, Cloudera puts unusual emphasis on bit-manipulation (40% of problems, 11.9x the industry average), dynamic-programming (40% of problems, 2x the industry average). If you're short on time, these are the categories to double down on.
The most common topics are bit-manipulation (40%), dynamic-programming (40%), array (20%), depth-first-search (20%). Problems below are sorted by frequency, the ones at the top are asked most often.

Cloudera interviews focus heavily on bit-manipulation, dynamic-programming, 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. Cloudera 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.
