Linked List in Binary Tree Given a binary tree root and a linked list with head as the first node. | Medium | Very Likely | linked-listtreedepth-first-search | Solve |
Check if Array Is Sorted and Rotated Given an array nums, return true if the array was originally sorted in non-decreasing order, then rotated some number of positions (including zero). Otherwise,... | Easy | Very Likely | array | Solve |
First Missing Positive Given an unsorted integer array nums. Return the smallest positive integer that is not present in nums. | Hard | Likely | arrayhash-table | Solve |

SoundHound interviews focus heavily on array, linked-list, tree problems. If you're short on time, these are the categories to prioritize. The problems on this page are sorted by frequency, so start from the top and work your way down.
Beyond solving problems, practice explaining your approach. SoundHound interviewers care about your thought process - how you break down a problem, consider edge cases, and evaluate tradeoffs between solutions. A clean O(n) solution you can explain clearly beats an O(log n) solution you can't articulate.
