Design a URL Shortening Service
Design a deliberately small URL-shortening core, then evolve it into a highly available service whose fixed logical shards can move safely as physical storage capacity grows.
Open practiceUber Freight interview practice
Practice from 1 Uber Freight-tagged public coding problem, organized only by the stage, topic, difficulty, and recency metadata FastPrep can verify. The broader public catalog also includes 3 system-design exercises, 1 low-level-design exercise.

01 · Preparation plan
Uber Freight's verified assets span three different engineering levels, so the useful preparation path is to make constraints explicit in an algorithm, a live aggregate, and an object model. Catalog labels guide practice but do not promise a current or universal hiring loop. This is a suggested practice sequence, not the employer's interview process. Your invitation and recruiter guidance remain the source of truth.
Use Maximize Compatible Car Riders to rehearse greedy feasibility over rider constraints. Keep the exercise's published contract separate from assumptions about Uber Freight's current interview process.
Use Design a Rolling Restaurant Analytics Dashboard to rehearse windowed realtime aggregates. Keep the exercise's published contract separate from assumptions about Uber Freight's current interview process.
Use Design an In-Memory File System to rehearse hierarchical state and concurrency contracts. Keep the exercise's published contract separate from assumptions about Uber Freight's current interview process.
02 · Broader technical practice
These public Uber Freight-tagged exercises cover additional technical formats. They are included only when a verified catalog record and a crawlable practice page both exist.

Open practice03 · Evidence boundary
It means practicing transferable implementation, testing, and technical reasoning with public catalog assets FastPrep tags to Uber Freight. It does not mean FastPrep has access to the company's assessments or any private interview bank.
Repeated public sightings and last-reported dates can help you prioritize practice, but they cannot predict the questions, format, or platform in a specific interview.
04 · Plain answers
This page owns technical-practice intent for Uber Freight. Hiring activity, timelines, and market signals remain on the separate hiring-insights page.
The launch review verified 1 coding exercise, 3 system-design exercises, 1 low-level-design exercise (5 total public practice items). The strongest reviewed themes are greedy feasibility over rider constraints, windowed realtime aggregates, hierarchical state and concurrency contracts. Counts and report labels can change, so use this as a focused practice library and follow your own invitation for the current format, timing, and permitted tools.
No. FastPrep is an independent interview-preparation product and is not affiliated with Uber Freight. The page uses FastPrep's public practice catalog and does not claim official, private, leaked, or proprietary employer questions.
Stage labels come from FastPrep's public problem metadata. A problem can carry more than one reported stage, and hiring processes can change by role, level, location, and date. Treat the labels as preparation context, not a guarantee.
Start with the stage named in your invitation or recruiter message. If no stage is known, use the largest available set to build general problem-solving fluency, then rehearse explanation and testing separately.
No. Public catalog counts, stage tags, and last-reported dates can help prioritize practice, but they cannot predict a specific interview's questions, sequence, timing, or platform.
Your next stage, made concrete
Start with the stage named in your invitation, then use public evidence as context—not as a promise of what you will be asked.
