I applied to Flexport on November 11 without refferal and received an assessment link on November 21. The assessment consisted of four DSA questions, all of LeetCode Medium/Hard difficulty.
Technical Interview Rounds
HR Screening (January 15):
The HR reached out to discuss the role and provide a brief overview of the interview process.
DSA Round:
This round focused on IP address validation:
Problem 1: Validate whether a given string is a valid IPv4 address (composed of four octets ranging from 0-255, separated by dots).
Follow-up: Given a string of digits, determine if it\'s possible to form a valid IPv4 address by keeping the numbers in sequence.
Example: \'127001\' \u2192 True (can be transformed into \'127.0.0.1\', \'12.70.0.1\', etc.).
I received the result the same day and was scheduled for the Machine Coding Round the following week.
Machine Coding Round:
The problem was to design and implement Splitwise. I was able to explain the system design well but couldn\'t fully implement the Low-Level Design (LLD) due to time constraints.
Verdict Cleared for the
next round.
Hiring Manager Round:
This round focused on:
My previous experience
Why Flexport?
High-Level System Design (HLD) questions
Final Outcome
I received the offer two days later.

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