Lenskart coding interview
questions, leaked.
2 problems reported across recent Lenskart interviews. Top patterns: array, two pointers, greedy. The list below is what most reported candidates actually saw, plus the honest play if you can't grind all of it.
Lenskart's coding assessment is lean. Two problems, both medium difficulty, both array-heavy. You're looking at Container With Most Water and Spiral Matrix type patterns. The good news: no hard problems means no exotic algorithms. The catch: medium difficulty at Lenskart means clean implementation under pressure. If you freeze on the two-pointer greedy logic or lose track of matrix boundaries mid-simulation, StealthCoder runs invisibly during your screen share and surfaces a working solution in seconds. You've got this, but you need to drill the patterns that show up.

You have a week, maybe less. You can't out-grind the list above. StealthCoder runs invisibly during the actual Lenskart OA. The proctor cannot see it. Screen share cannot detect it. Made by a working FAANG engineer who treats the OA the way companies treat hiring: as a game with rules you should know.

Array manipulation dominates here. Container With Most Water tests two-pointer thinking and greedy choices. Spiral Matrix hits simulation and boundary management. You won't see dynamic programming, trees, or graphs on this assessment. Your time is better spent getting comfortable with array iteration patterns and understanding when greedy works versus when it doesn't. The two-pointer technique appears once directly but underpins how you'll solve Container With Most Water cleanly. Spiral Matrix will test whether you can track row and column boundaries without off-by-one errors. If you haven't practiced the spiral traversal pattern, that's where StealthCoder becomes your safety net during the live 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 FAANG engineer who treats the OA the way companies treat hiring: as a game with rules you should know. Works on HackerRank, CodeSignal, CoderPad, and Karat.
Lenskart interview FAQ
Should I focus on two-pointer problems for Lenskart?+
Yes. Two-pointer appears explicitly in Container With Most Water and underpins the greedy approach needed there. That's one of your two problems. Spend time understanding the expanding window logic and why greedy bounds-chasing works. Don't skip it.
Is matrix traversal really that important here?+
It is. Spiral Matrix is one of your two assessment problems and tests simulation plus boundary tracking. Matrix traversal isn't just one topic, it's simulation applied to 2D grids. Getting comfortable with layer-by-layer or direction-based traversal is non-negotiable for Lenskart.
Do I need to study hard problems before my Lenskart OA?+
No. Lenskart's assessment contains zero hard problems. Both are medium. Skip the grinding on LeetCode hard. Drill medium-difficulty array and simulation problems instead. Your time is better spent on clean, correct implementations of the patterns that actually appear.
How many array problems should I solve before the assessment?+
Array is your foundation. Both Lenskart problems involve arrays. Solve at least 10 to 15 medium-level array problems covering iteration, two-pointers, and greedy approaches. Focus on the patterns, not the count. Quality beats volume here.
What topic should I study first for Lenskart?+
Array. It's the spine of both problems on the assessment. Once you're solid on array manipulation, move to two-pointer and greedy techniques. Matrix and simulation are built on top of strong array fundamentals. Start there and your confidence will carry through.
