Based on 5 reported problems, Darwinbox interviews are significantly harder than average - 40% Hard vs 18% across all companies. The majority (60%) 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, Darwinbox puts unusual emphasis on 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 array (80%), dynamic-programming (40%), string (20%), matrix (20%). Problems below are sorted by frequency, the ones at the top are asked most often.
| Problem | Difficulty | Frequency | Topics | |
|---|---|---|---|---|
Scramble String We can scramble a string s to get a string t using the following algorithm: | Hard | Very Likely | stringdynamic-programming | Solve |
Spiral Matrix Given an m x n matrix, return all elements of the matrix in spiral order. | Medium | Likely | arraymatrixsimulation | Solve |
Majority Element II Given an integer array of size n, find all elements that appear more than ⌊ n/3 ⌋ times. | Medium | Likely | arrayhash-tablesorting | Solve |

Darwinbox interviews focus heavily on array, dynamic-programming, string 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. Darwinbox 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.
