Coding questions · AMD
Find the Largest K Elements with Partitioning
Find the largest k occurrences with partition-based selection, sort only the output, and compare quickselect pivot risks with heap and full-sort alternatives.
Coding questions · Amazon
Find the Largest Rating Threshold Supported by K Instances
Find the largest k for which at least k instance ratings are at least k, handling threshold equality and the zero-answer case.
Coding questions · Stripe
Find the Latest Balance for a Bank Account
Query the latest dated bank-account balance using both bank and account identifiers while handling records across months and years.
Coding questions · Agoda
Find the Longest Calendar-Day Streak with All Employees Present
Identify dates when every employee is present and compute the longest consecutive streak, treating missing attendance as a gap.

Find the Lowest Common Ancestor of Two Nodes in an N-ary Tree
Given a rooted tree whose nodes can have any number of children, stored as child lists, return the lowest common ancestor of two labeled nodes. The problem generalizes the binary-tree version to arbitrary fan-out and tests tree traversal, ancestor reasoning, and robust handling of very deep, path-shaped trees.
Coding questions · Snowflake
Find the Minimum Bus Fleet with Station Constraints
Minimize a bus fleet when trips have origin and destination stations, tracking when buses become available at the correct departure station.
Coding questions · Snowflake
Find the Minimum Fleet for a Bus Timetable
Find the minimum number of buses needed for a timetable by tracking overlapping trips and allowing reuse at equal arrival and departure times.
Coding questions · Pinterest
Find the Minimum Number of Coins for an Amount
Find the minimum number of unlimited-denomination coins needed to form an exact target amount. This portable version of the standard referenced problem defines impossible and zero amounts, duplicate denominations, numeric bounds, and two examples for later cross-language console verification.
Coding questions · IBM
Find the Minimum Shared Increment on Nonadjacent Array Positions
Choose nonadjacent indices for one common nonnegative increment to make an array nondecreasing, or determine that no operation can succeed.
Coding questions · Salesforce
Find the Minimum Word Transformation Steps
Compute the minimum number of one-character transformations between equal-length words when every intermediate word must belong to a supplied dictionary, returning failure when no path exists.

Find the Most Frequent Log Call
This question evaluates a candidate's ability to perform frequency analysis on sequences, demonstrating competency with data structures for counting occurrences and with algorithmic time and space complexity considerations.
Coding questions · Meta
Find the most-used app
This question evaluates data manipulation and metrics-definition skills, emphasizing SQL and Python proficiency for aggregating user activity and joining app metadata within analytics workflows.
Coding questions · Microsoft
Find the Most Visited Track Position
Count visits along inclusive sprint intervals in either direction and return the smallest numbered position among those visited most often.
Coding questions · Waymo
Find the N-th Positive Integer Whose Digits Are All 3, 5 or 6
Positive integers whose digits are only 3, 5 or 6 are called good numbers; return the n-th good number in increasing order as a string for n up to one trillion. Tests counting by digit length and mapping the rank to a base-3 style digit sequence.

Find the Next Larger Palindrome
This question evaluates proficiency in numeric and string manipulation, algorithmic thinking, and edge-case reasoning related to palindromic number generation.
Coding questions · LinkedIn
Find the Node Where Two Singly Linked Lists Merge
Two singly linked lists stored in one successor array may merge at some node and share every node after it. Given both heads, return the first shared node, or -1 if the lists never meet. It tests linked-list traversal and careful handling of cases such as one list starting inside the other.

Find the Super Admin User Who Can Access Every Camera Through Nested Groups
Given permission triples linking users, groups and cameras, find the user who can access every camera through direct ownership or through nested, possibly cyclic group memberships. It tests modeling permissions as a directed graph, reachability that tolerates membership cycles, and edge cases such as an input with no cameras or a group that covers everything.

Find the Top-Left Submatrix Matching a Grid Pattern With Letter Variables
Locate a pattern grid inside an integer matrix, where each pattern cell is either an exact number or a letter that must stand for one consistent value, and return the top-left corner of the match with the lowest row and then the lowest column. It tests two-dimensional scanning, variable binding, and tie-breaking rules.
