PornHub coding interview
questions, leaked.
9 problems reported across recent PornHub interviews. Top patterns: array, string, binary search. The list below is what most reported candidates actually saw, plus the honest play if you can't grind all of it.
PornHub's interview loop hits you with nine problems across a narrow band of patterns. Two easy, four medium, three hard. Arrays dominate the surface, but the real story is binary search and dynamic programming stitched into every third problem. You're walking in cold, you blank on "Median of Two Sorted Arrays" or "Split Array Largest Sum", and suddenly you're rewriting your mental model mid-OA. That's where StealthCoder runs invisible during screen share and surfaces a working solution in seconds, no proctor knowledge. The prep is real. The backup is invisible.

Array problems anchor the dataset with five appearances, but they're almost never standalone. They pair with binary search, divide-and-conquer, or DP to force you into harder thinking. String and hash-table show up together often, especially in sliding-window and trie problems. Binary search appears in three problems, all hard or medium, all built on sorted arrays or monotonic assumptions. Dynamic programming is your third pattern: "Extra Characters in a String", "Maximum Subarray", and "Split Array Largest Sum" all require you to think in states and transitions. Hit arrays and strings first, not because they're easier, but because they're the foundation. Then drill binary search on sorted structures, especially the rotated-array variant. If you hit a DP problem cold during the OA, StealthCoder is your hedge.

PornHub interview FAQ
Should I study arrays and strings first for this interview?+
Yes. Arrays appear in five of nine problems here, strings in four. But don't treat them as isolated topics. Study them alongside binary search, hash tables, and DP, since problems like "Extra Characters in a String" and "Median of Two Sorted Arrays" blend three patterns at once.
How much binary search practice is enough?+
Three of nine problems here use binary search, all at medium or hard difficulty. Spend time on "Median of Two Sorted Arrays" and "Split Array Largest Sum". Binary search is easy to botch mid-OA. Practice until you can write the boundaries correctly without thinking.
Is dynamic programming mandatory preparation?+
It shows up in three problems including two hard ones. "Maximum Subarray" and "Split Array Largest Sum" both require DP or greedy thinking. If DP isn't solid, these become time sinks. Drill state transitions and recurrence relations.
What's the ratio of easy to hard, and how should that shape my week?+
Two easy, four medium, three hard. You can't bank on easy problems to carry you. Spend 70 percent of your time on medium and hard patterns, especially the ones that combine topics like "Longest Substring Without Repeating Characters" and "Reverse Nodes in k-Group".
Should I memorize hash-table and trie solutions?+
Hash tables and tries appear together in three problems here, often merged with strings or arrays. Understand the mechanics instead. "Longest Common Prefix" and "Extra Characters in a String" test whether you can apply them in context, not recall a template.
