Ola Cabs coding interview
questions, leaked.
2 problems reported across recent Ola Cabs interviews. Top patterns: array, dynamic programming, string. The list below is what most reported candidates actually saw, plus the honest play if you can't grind all of it.
Ola Cabs interviews are lean. Two problems in the dataset, one easy and one medium, which means you're not drowning in backlog data here. The topics that matter are array, dynamic programming, string, stack, and recursion. If you get stuck on the live assessment, StealthCoder runs invisibly and surfaces a solution in seconds. The real edge is knowing what's actually been asked before you walk in.

You have a week, maybe less. You can't out-grind the list above. StealthCoder runs invisibly during the actual Ola Cabs 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.

The problem set skews toward classic patterns. Best Time to Buy and Sell Stock is a foundational dynamic programming greedy play on arrays. Decode String hits string parsing with stack and recursion, a pattern that catches people off guard. Topic spread is wide but shallow, which is typical for a smaller dataset. That means you can't bet on getting the exact same problem twice. What you can do is master the mechanics of DP on sequences and recursive string traversal. If you freeze mid-problem on a recursion chain or can't build the DP table, StealthCoder closes that gap during the actual OA.

Memorizing every problem above in a week is a fantasy. StealthCoder is the hedge: an AI overlay that's invisible during screen share. It reads the problem on screen and surfaces a working solution in under 2 seconds. Made by a working Amazon engineer who got tired of watching qualified friends bomb OAs they'd solve cold in an IDE. Works on HackerRank, CodeSignal, CoderPad, and Karat.
Ola Cabs interview FAQ
What should I study first for Ola Cabs?+
Start with array and dynamic programming together. Best Time to Buy and Sell Stock is the reported problem, and it bridges both. Once that's solid, move to string manipulation with stack and recursion. All five topics appear in the dataset, but the DP/array combo is the load-bearing wall.
Is one easy and one medium enough to predict interview difficulty?+
No. Two problems is a small sample. What you can infer is that the company asks a mix. Expect medium to dominate in the real assessment. The dataset has no hard problems reported, but that doesn't mean they won't appear. Treat it as a floor, not a ceiling.
How should I approach recursion problems for this interview?+
Decode String is the template here. It requires recursive string unwinding with a stack. Practice building and unwinding stacks inside recursive calls. Focus on base cases and the mechanics of returning partial results up the call chain. This pattern repeats in real interviews.
Will I see a DP problem on the assessment?+
Probably. Best Time to Buy and Sell Stock has been reported, and it's a classic DP pattern. Even if you don't get that exact problem, expect state-table or memoization questions. Build muscle memory on the setup and transition logic now.
What's the fastest way to prepare if I have a week?+
Two problems, five topics. Drill Best Time to Buy and Sell Stock until it's automatic. Then spend the remaining time on Decode String and variations of recursive string parsing. That covers the ground. On OA day, if you hit something unfamiliar, you're covered.
