19. Product of Array Except Self
Given an array, return an array where each element is the product of all other elements — without using division and in O(n) time. Intuit asks this to test prefix/suffix patterns and to probe whether you avoid division (which fails on zero) in financial calculations.

20. Subarray Sum Equals K
Given an integer array and an integer k, return the number of contiguous subarrays whose sum equals k. Intuit asks this to test the prefix-sum + hash-map pattern and to reframe it as 'count ledger windows that reconcile to a target balance.'

21. Palindromic Substrings
Count the number of palindromic substrings in a string. Intuit asks this as a string-DP warm-up and to probe whether you can pick the right expansion approach over the obvious DP table.

Karat Technical Interview Guide 2026: How the Third-Party Loop Actually Works
Karat is technical-interview-as-a-service. Karat-employed engineers run the technical loop for the hiring company in Karat's own recorded video and coding environment. The dynamic is different from an in-house interview: the interviewer is a contractor, not a future teammate, the rubric is fixed, the session is recorded for asynchronous review, and the hiring team's engineers watch the playback a day later. This guide is the practical map of how that loop works in 2026 and how a modern desktop setup runs alongside it.
