Cashfree coding interview
questions, leaked.
3 problems reported across recent Cashfree interviews. Top patterns: array, binary search, dynamic programming. The list below is what most reported candidates actually saw, plus the honest play if you can't grind all of it.
Cashfree's coding assessment is tight and medium-difficulty throughout. Three problems, all MEDIUM, zero easy warm-ups and zero hard curveballs. Array patterns dominate the assessment, appearing in every single problem. This is a depth-over-breadth test: they're not checking if you know ten topics, they're checking if you can manipulate arrays under different constraints. House Robber IV pulls in binary search and dynamic programming together. Maximum Erasure Value demands sliding-window and hash-table speed. Non-decreasing Array is pure array mutation logic. If you freeze mid-OA on any of these, StealthCoder runs invisibly and surfaces a working solution in seconds.

You have a week, maybe less. You can't out-grind the list above. StealthCoder runs invisibly during the actual Cashfree OA. The proctor cannot see it. Screen share cannot detect it. Built by an Amazon engineer who realized the OA tests how well you memorized 200 problems, not how well you code.

Three problems means no room for half-measures. Array fundamentals are non-negotiable here. Beyond arrays, the assessment spreads across binary search, dynamic programming, greedy, hash tables, and sliding windows, but never repeats any of those patterns. This tells you Cashfree is testing your ability to recognize when to apply which technique to array data. Binary search and DP in House Robber IV is the hardest lever on this assessment, so drill that combination first. Sliding window with hash tables in Maximum Erasure Value is the speed round, where clean implementation matters more than deep thinking. Non-decreasing Array is your confidence check: if you nail the array mutations, you've got a baseline. If you hit a wall during the live OA on any pattern, StealthCoder is your hedge, solving it behind the screen while you stay calm.

Cashfree interview FAQ
How much time should I spend drilling array problems for Cashfree?+
Most of it. Array manipulation appears in all three problems on their assessment. Spend 50 to 60 percent of your prep on array patterns, then split the rest between binary search, dynamic programming, and sliding windows. Greedy and hash tables are secondary.
Is House Robber IV the hardest problem on Cashfree's OA?+
Yes. It combines binary search, DP, and greedy reasoning on arrays, which is the most complex pattern in their assessment. The other two problems are solid MEDIUM but more straightforward. Nail House Robber IV logic first.
Do I need to study greedy algorithms separately for Cashfree?+
No separate prep needed. Greedy reasoning appears only in House Robber IV, bundled with binary search and DP. Once you solve that problem, you've got the greedy patterns they care about.
Should I practice sliding window or hash tables first?+
Sliding window. It's the core technique in Maximum Erasure Value, paired with hash-table logic to track erasure value. Master the window movement, then layer in the hash map for O(1) lookups.
What if I blank on the binary search angle in House Robber IV?+
That's what the OA is risky for. You drill it now so you don't blank. But if you do mid-assessment, StealthCoder solves it invisibly and gives you the approach to execute. No proctor sees it.
