Stripe OA 2026: Real Exam Questions & Preparation Guide

Stripe OA questions coding 1

Given a grid composed of black and white squares, with rows rows and cols You will also get an array named black, which contains the coordinates of all black squares (in the format of [row, column]).

Your task is: find out how many small squares (that is, sub - matrices of 2 rows and 2 columns) in this grid exactly contain 0 to 4 black squares. Finally, you need to return an array of length 5, where the i - th position of the array represents: the number of small squares with exactly i black squares.

The problem guarantees that each coordinate in the black array is different, and there will be no repeatedly marked squares.

Example

The size of the grid is 3 rows and 3 columns (rows = 3, cols = 3). The coordinates of the black squares are [[0, 0], [0, 1], [1, 0]]. The grid you get is like this =>

Among all possible \(2 \times 2\) small squares.

  • There is 1 small square with no black squares at all.
  • There are 2 small squares containing 1 black square.
  • There are 0 small squares containing 2 black squares.
  • There is 1 small square containing 3 black squares.
  • There are 0 small squares containing 4 black squares.

Therefore, the output is. [1, 2, 0, 1, 0].

Stripe OA questions coding 2

There is a group of mysterious numbers (numbers), among which there are some number pairs. They have the same length, and only one digit is different. Your task is to find the number of such number pairs.

Requirements:
Given a numeric array Numbers, find all number pairs (i,j) that meet the conditions, where.

  • I is less than J.
  • The number pairs have the same length.
  • Only one digit is different.

Example:
Input: numbers = [1,151,241,1,9,22,351]
Output: 3
Explanation.

  • The numbers 1 And 9 differ by one digit, so they are a number pair.
  • The numbers 151 And 351 differ by one digit, so they are a number pair.
  • The numbers 1 And 9 form a number pair again (because there are multiple 1s in the array).
  • The same numbers (such as two 1s) cannot be counted as a number pair.

Stripe OA questions coding 3

In the dynamically evolving realm of web hosting, providing clients with a clear asset overview is key to enhancing user experience. The development team needs to create a feature for the dashboard of online hosting clients to generate a report on all clients and the number of active websites they own.

The report results should include the following columns.

  • email:: The client's email address
  • total_active_sites:: The total number of active websites per client

The results should be sorted in ascending order by email.

Note:: Only include active websites.

Table Structure

  • customers
    • id (integer, primary key): The client's identifier
    • email (VARCHAR(255)): The client's email address
  • sites
    • Customer_id (integer, foreign key): Pointing to the client's ID
    • url (VARCHAR(255)): The website's URL
    • is_active (boolean): The status of the website (1 indicates active. 0 indicates inactive)

Why Stripe Likes This Question

  • Extremely realistic business scenario
  • Tests JOINs, filtering, grouping
  • Very similar to actual Stripe internal reporting logic
  • Easy to fail if inactive rows aren’t filtered correctly

Key Takeaways from Stripe OA

From real Stripe OA experiences, a few patterns are clear:

  • Questions are not algorithm-heavy, but logic-heavy
  • Business context matters more than clever tricks
  • Edge cases and constraints are frequently tested
  • SQL questions are common and highly practical

Grinding random LeetCode questions is far less effective than practicing Stripe-style problems.
