Coveo coding interview
questions, leaked.
2 problems reported across recent Coveo interviews. Top patterns: array, two pointers, dynamic programming. The list below is what most reported candidates actually saw, plus the honest play if you can't grind all of it.
Coveo's coding assessment is lean but punishing. Two problems total, split between medium and hard, means every line of code counts and there's zero room for half-solutions. You're looking at array manipulation under constraint, which demands both pattern recognition and clean execution. The good news: the problem set is small enough to lock down completely. The catch: they're testing whether you can think in two pointers and dynamic programming simultaneously, not just solve toy cases. If you hit a wall on the hard problem mid-assessment, StealthCoder runs invisibly and surfaces a working approach in seconds.

You have a week, maybe less. You can't out-grind the list above. StealthCoder runs invisibly during the actual Coveo OA. The proctor cannot see it. Screen share cannot detect it. Made by a working Amazon engineer who got tired of watching qualified friends bomb OAs they'd solve cold in an IDE.

Arrays dominate the assessment, appearing in both problems. Two-pointers is the connector tissue: it shows up in the medium problem and shadows the hard one as a valid approach. The hard problem, Trapping Rain Water, is the real test. It can be solved with brute force, two pointers, or a monotonic stack, and Coveo wants to see you pick the right tool. The medium problem, Container With Most Water, is a two-pointer warm-up that filters out candidates who don't know the pattern. If you blank on optimizing the hard problem during the live assessment, StealthCoder is your safety net, surfacing a working solution invisible to the proctor so you can move forward.

Coveo interview FAQ
How much time should I spend drilling two-pointer problems before the Coveo assessment?+
Both Coveo problems use two pointers as a core technique. Spend the bulk of your prep time on this pattern. Container With Most Water is the easier entry point; master that, then move to the hard problem where two pointers compete with other approaches. You need to recognize when two pointers is the right choice, not just how to code it.
Do I need to know monotonic stacks for Coveo?+
Trapping Rain Water, the hard problem, can be solved elegantly with a monotonic stack. It's not required, but it's the optimal approach for Coveo's bar. Two-pointer and dynamic-programming solutions work too, so if monotonic stacks are new to you, learn the two-pointer version first and build up from there.
Is dynamic programming necessary for this assessment?+
Dynamic programming appears as one valid approach to Trapping Rain Water, but it's not the fastest. The two-pointer and monotonic-stack methods are more efficient. Understand the DP solution for completeness, but prioritize optimized approaches since Coveo is testing algorithmic thinking, not just correctness.
What should I practice first for Coveo, the medium or hard problem?+
Start with Container With Most Water. It teaches the two-pointer pattern cleanly and you can solve it in under five minutes once you know the trick. Then attack Trapping Rain Water, which forces you to extend that thinking. The medium primes your brain for the hard problem's constraints.
Can I pass the Coveo assessment without a monotonic-stack solution?+
Yes. Both array-based problems accept multiple approaches. Two pointers and dynamic programming work for the hard problem. The trade-off is runtime efficiency. Coveo likely accepts correct solutions across approaches, but the cleanest code wins under time pressure. If you're comfortable with DP, use it. If not, two pointers is your fallback.
