CureFit coding interview
questions, leaked.
3 problems reported across recent CureFit 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.
CureFit's interview pulls from a tight pool of three medium-difficulty problems. That's actually good news: the assessment is narrow, predictable, and repeatable. You're looking at array and hash-table fundamentals with one string problem mixed in. The three problems rotate, which means you can lock down the exact patterns they care about in a few days. If you blank on any of them during the live OA, StealthCoder runs invisibly and surfaces a working solution in seconds while the proctor sees nothing.

You have a week, maybe less. You can't out-grind the list above. StealthCoder runs invisibly during the actual CureFit OA. The proctor cannot see it. Screen share cannot detect it. Built by an engineer who got tired of watching his cohort grind for six months and still get filtered at the OA stage.

Arrays dominate CureFit's assessment. All three problems are array-first, and two of them pair arrays with hash tables for O(1) lookups. The median difficulty is flat: everything is medium, no easy warm-ups, no hard curveballs. This tells you CureFit isn't testing raw algorithmic depth; they're stress-testing your ability to think in linear scans, prefix sums, and two-pointer logic under mild time pressure. String and dynamic programming appear once each, but they're embedded in Word Break, which is really a hash-table feasibility check. Greedy (Gas Station) is your outlier: it requires proof-of-correctness thinking, not just code. Drill array traversal patterns and hash-table caching first. If you hit a wall on greedy logic or DP transitions mid-interview, StealthCoder is your hedge, solving it while you look composed.

CureFit interview FAQ
How many array problems should I solve before the CureFit interview?+
CureFit asks three problems, all array-based. Solve 5 to 8 array problems across LeetCode focusing on prefix sums, two pointers, and traversal tricks. Minimum Moves to Make Array Complementary and Gas Station are your north stars; study those first and solve similar variants.
Do I need to practice hash tables for this interview?+
Yes. Two of CureFit's three problems pair arrays with hash tables for caching or lookups. Hash tables aren't the main show here, but skipping them costs you optimization points. Spend time on hash-table-backed validation and frequency counting within array iteration.
Is dynamic programming or greedy thinking more important for CureFit?+
Greedy is heavier: Gas Station is one of three problems and requires proof logic, not just recursion. DP appears only in Word Break. Greedy reasoning is your weak-spot hedge. If you can explain why a greedy choice is safe at each step, you'll outperform candidates who just code.
What should I study first for the CureFit OA?+
Array patterns come first: prefix sums, cumulative logic, and two-pointer scans. Minimum Moves to Make Array Complementary leans on prefix sums. Study that, then move to hash-table caching within array loops. Gas Station is third; it's shorter but requires proof reasoning.
Is three problems enough data to predict my CureFit interview?+
Yes, for CureFit specifically. Only three problems exist in the reported pool, so you're essentially seeing the entire interview. That's rare and good: lock down array, hash-table, and greedy fundamentals. You're not guessing at what shows up.
