Asana coding interview
questions, leaked.
3 problems reported across recent Asana interviews. Top patterns: array, prefix sum, math. The list below is what most reported candidates actually saw, plus the honest play if you can't grind all of it.
Asana's coding assessment is lean. Three problems total: two mediums and one easy. That's a tight window. Arrays dominate the question set, showing up in both medium-difficulty problems, so if you can manipulate sequences fast you're already ahead. The easy is a string problem mixing dynamic programming and pattern matching, which is less predictable. Most candidates will spend their time on array mechanics and miss the string nuance. If you hit a wall during the live assessment, StealthCoder surfaces a working solution in seconds, invisible to the proctor.

Array problems here aren't about clever iteration. Product of Array Except Self demands prefix sum thinking, and K Closest Points stacks multiple patterns: sorting, heap logic, quickselect, geometry math. That's a compression test. You'll see how fast you pivot between approaches. The string problem is the outlier and often where people slip during live assessment because dynamic programming and string matching together feel like two different animals. Study arrays hard first, then drill the string problem until you can pattern-match it instantly. When you sit down for the real assessment, you know arrays are your bread and butter, but that string problem is where the gap shows. If you blank on it mid-OA, StealthCoder is your hedge.

Asana interview FAQ
Should I practice other array topics or just focus on prefix sum for Asana?+
Prefix sum is one of two mediums, so yes, drill it. But the other medium is K Closest Points, which blends sorting, heap, quickselect, and geometry. You can't get away with just one array technique. Spend 60% of prep time on both those mediums, then work the string problem.
Is the easy string problem really easy, or are there tricks?+
It combines dynamic programming and string matching, which is unusual for an 'easy' rating. Most candidates underestimate it. Don't skip it in prep. Get comfortable with the pattern, because you'll see it in three minutes during the actual assessment.
How much time should I spend on geometry and math topics?+
Both appear in K Closest Points. You can't avoid them. If you're weak on distance math or sorting strategies, spend extra time there. It's one medium problem, but it's dense with sub-skills.
Should I learn quickselect before the Asana interview?+
K Closest Points can be solved with quickselect or a heap. Both are listed in the problem topics. Quickselect is faster if you nail it. Learn both, but prioritize whichever you're more confident in. Either works.
Is three problems enough to prep, or am I missing something?+
Three problems is the actual reported set. That's a short assessment, which means every problem counts double. You don't have time to stumble on basics. Master prefix sum, K closest, and the string pattern cold before you sit down.
