Question: Implement a NUMBER guessing game. The user must guess a 4-digit number (without repeats). The user has 7 attempts. Every attempted guess must be a 4-digit number. They either: wins (guessed the number correctly) loses (7th attempt is wrong) or get "tip": X bulls, Y cows, where: X is the number of correct digits in correct positions Y is the number of correct digits, but wrongly positioned. For example, the number is "1234". Attempt 1290 will result in a tip: 2 bulls, 0 cows. Attempt 1234 will be WIN. Attempt 1562 will result in a tip: 1 bull, 1 cow. Comments It should be a CLI program. 0123 - an invalid number (can't start with 0) 1023 - is valid 1123 - is invalid (digits repeat). Every time a user starts a game, they should get a random number to guess. Bonus: Print "Gutter ball!!!" if the user hits 0 bulls and 0 cows. Every time the user starts a game, they should get a DIFFERENT number to guess (never repeat the same number)!
Tip: More than implementation focus on setting up test cases first and be ready to write unit test cases class and test it.

About Shopify Interview Reports
This question was reported by a candidate who interviewed at Shopify. LeakCode aggregates interview reports from 10+ sources, including 1Point3Acres, Glassdoor, LeetCode Discuss, Blind, Reddit, Indeed, and Nowcoder. Each report is translated where necessary, deduplicated against existing entries, and tagged by company, role, round type, and reporting date.
Use this question as one calibration data point, not a memorization target. Companies typically rotate their question pools every 2-4 months; the exact wording of a 2024 question may differ from what you encounter today. The underlying pattern, difficulty level, and follow-up depth at Shopify are the higher-signal extractions to take from this report.
For broader preparation context, the Shopify interview process typically includes a recruiter screen, one or two technical phone screens, and a 4-5 round on-site loop covering coding, system design (at L4+ levels), and behavioral. Reports tagged on LeakCode show the round-by-round distribution and typical difficulty calibration. To browse questions filtered by round type and seniority, use the company hub linked above.
How To Practice This Type of Question
Solve similar problems on LeetCode under timed conditions (25-35 minutes per medium difficulty). The goal is pattern recognition: recognize the underlying technique (sliding window, two-pointer, BFS, memoized recursion, etc.) within 60-90 seconds of reading. Strong candidates verbalize their hypothesis out loud before coding, then iterate based on feedback. Weak candidates dive into implementation immediately, lose time on the wrong approach, and run out of time for follow-ups.
Companies update their question pools every 2-4 months. The exact wording of any given question may have been retired by the time you interview. Focus your prep on the pattern, not the specific problem. The patterns that appear in Shopify reports consistently are the ones worth investing in; one-off niche problems are not.
During Your Shopify Round
Apply the standard interview round template: clarify requirements (2-3 minutes), state your approach out loud and confirm direction with the interviewer (3-5 minutes), code with narration (15-25 minutes), test with concrete examples including edge cases (5 minutes), discuss optimization or trade-offs if time permits (5 minutes). This template is universally accepted across FAANG and adjacent companies; deviating from it produces weaker interviewer feedback signal.
The single most predictive failure mode in Shopify reports tagged "no hire": not asking clarifying questions. Interviewers are explicitly trained to weight this. Strong candidates ask 3-5 clarifying questions even on problems that look obvious; weak candidates dive into code immediately. The clarifying-question check is often the first signal recorded in the interviewer's written notes.
