Asana Coding Interview Questions
26 Asana coding interview problems with full optimal solutions — 15 easy, 10 medium, 1 hard. Every problem ships with multiple approaches (brute-force first, then the optimal), complexity tables for each, company-specific tips on what an Asana interviewer values, and a FAQ section.

22. Climbing Stairs
Count the distinct ways to reach the top of an n-step staircase using 1 or 2 steps at a time — Asana uses this Fibonacci-DP warmup to assess how cleanly you reduce a novel problem to overlapping subproblems before coding.

1. Two Sum
Given an array of integers and a target, return the indices of two numbers that add up to the target. Asana opens with this to confirm you reach for hash maps reflexively before quadratic loops — a baseline signal before they pivot to graph problems.
- #2easyfrequently asked
2. Valid Parentheses
Determine if a string of brackets is balanced and properly nested. Asana asks this to test whether you reach for a stack reflexively — the same data structure underpins their task-dependency cycle checks.
- #3easyfrequently asked
3. Merge Two Sorted Lists
Merge two sorted linked lists into one sorted list by splicing nodes together. Asana asks this to confirm you can handle pointer manipulation cleanly — a building block for their dependency-resolution merge step.
- #8easyfrequently asked
8. Merge Sorted Array
Merge two sorted arrays in-place, where the first has extra trailing slots. Asana asks this to test whether you spot the back-to-front trick — they care because the same insight powers their activity-feed merge logic.
- #9easyfrequently asked
9. Binary Tree Inorder Traversal
Return the inorder traversal of a binary tree. Asana asks this to confirm you can implement both recursive and iterative tree walks — they care because the iterative pattern is what powers their cycle-free dependency walker.
- #12easyfrequently asked
12. Maximum Depth of Binary Tree
Find the maximum depth of a binary tree. Asana asks this to confirm you can write the simplest tree recursion cleanly — a baseline before they ask about deep project-hierarchy traversals.
