The position is Engineering Lead, reporting to a senior manager. 50% of the time will still be spent coding. First, there's a chat with HR, then team matching. Once a manager accepts the position, the interview process begins. Phase 1 Final Round 1. LeetCode problems under Easy and Medium difficulty. The questions weren't actually LeetCode problems, but they weren't difficult, and the East Asian guy gave hints. 2. Backend Systems Design, Netflix. A white guy, from another team, EL. Passing these two will allow you to proceed to the next phase. Phase 2 One 60-minute technical deep dive interview. You'll need to describe a previous project, which you need to prepare in advance and send to HR. It should be about three pages long, and specific questions are provided. Business Overview (including an ERD-type image/diagram has been helpful) What Made The Project So Impactful/Challenging? What Risks Did You Take? Success Metrics What Technologies Did You Use? Can you explain those technologies in depth and why you worked with them? Role: You Held on The Project - How Do Your Contributions Make You Stand Out? Technical Decisions and Trade-Offs What The Rollout Plan Was What The Results Were What Were the Lessons Learned & How Did You Share With The Team? One 45-minute behavioral interview with the hiring manager One 45-minute behavioral interview with a peer of the hiring manager Technical & Product Strategy: Basic team management questions. Hiring Manager Interview - Team Building The Indian guy, failed. Clearly not interested in me. Feedback can be requested later; the questions are from the final hiring manager interview. Overall, everyone seemed very nice, and communication was smooth. The culture seemed great.

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