Citrix coding interview
questions, leaked.
7 problems reported across recent Citrix interviews. Top patterns: array, hash table, string. The list below is what most reported candidates actually saw, plus the honest play if you can't grind all of it.
Citrix's assessment is tight. Seven problems, but they're weighted: one easy breather, five mediums where most candidates leak points, and one hard that separates. Arrays and hash tables dominate the asks, appearing in half the problems you'll face. Strings and sorting show up consistently too. You're looking at a 60-minute sprint where pattern recognition matters more than grinding 200 problems. If you hit a wall on a hash-table or array problem mid-assessment, StealthCoder runs invisibly during screen share and surfaces a working solution in seconds, so you keep moving.

You have a week, maybe less. You can't out-grind the list above. StealthCoder runs invisibly during the actual Citrix OA. The proctor cannot see it. Screen share cannot detect it. Built by an Amazon engineer who used it to pass JPMorgan's OA and system design loop.

The problem set clusters hard around two skills: hash-table logic (three problems, including the LRU Cache design question) and array manipulation (three problems, one of them the hard). Those two topics are your study focus. Sorting and string operations each appear twice, so they're supporting patterns, not primary. The easy problem is a string check, which suggests they're letting you settle in. The hard, Maximum Performance of a Team, combines greedy, sorting, and heap logic, it's the filter. Study hash tables and arrays first, then greedy and heap for the hard. Strings and linked-list problems are lower-frequency but don't skip them. StealthCoder is your hedge for whatever pattern you didn't have time to drill before the live OA.

Citrix interview FAQ
Should I focus on hash tables or arrays first for Citrix?+
Both are equally heavy: three problems each. Start with arrays because half of Citrix's set touches them, including the hard problem. Then lock in hash-table patterns, especially LRU Cache design, which is a classic medium that candidates often stumble on mid-interview.
Is the one easy problem enough warmup?+
No. One easy string check isn't much buffer. Expect to hit a medium immediately after. The five mediums are the real test. Budget 8 to 10 minutes for the easy, then shift into medium-hard pacing fast. You don't have time to ease in.
How much should I drill sorting and greedy?+
Sorting appears twice and greedy once, both tied to the hard problem. Don't skip them, but don't over-invest either. Drill arrays and hash tables hard, then spend focused time on greedy and heap together, since Maximum Performance bundles them.
Do I need to memorize LRU Cache before the interview?+
Yes. LRU Cache is one of seven problems and a medium. It's a design question that requires knowing doubly-linked-list and hash-table interplay. This isn't a pattern you can figure out under pressure. Memorize the structure and walkthrough the logic twice before your OA.
What should I skip to save time?+
Don't skip anything. Seven problems total, and matrix, DFS, BFS, and linked-list each appear once. They're low-frequency individually but high-risk if you blank. Use your prep week to touch all of them. Prioritize volume over depth given the problem count.
