Full Details
It's the Greenhouse job board that many companies use now. I saw quite a few companies using it when I was applying for jobs. After the call with HR, I talked to the hiring manager about past projects. Just finished the technical interview. It was quite simple: parse string input, then integrate it and output a new string according to the requirements. The code needs to be clean, tidy, and reusable. The input format is roughly: " title, organization, city, state, minSalary, maxSalary title, organization, city, state, minSalary, maxSalary The following content requires a score higher than 110. You can already view it. The input is Title: xxx, Organization: xxx, Location: (city)-(state), Pay: (min)-(max) ... There are 3 parts in total. part1:
Output all jobs, sorted by title part2:
Output jobs in a certain province, sorted by title part3: Change the logic of outputting provinces in part2 to O(1) method ! I wish everyone gets their desired offer

About Greenhouse Interview Reports
This question was reported by a candidate who interviewed at Greenhouse. 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 Greenhouse are the higher-signal extractions to take from this report.
For broader preparation context, the Greenhouse 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 Greenhouse reports consistently are the ones worth investing in; one-off niche problems are not.
During Your Greenhouse 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 Greenhouse 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.
