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 practiceDigitalOcean interview practice
Practice from 1 DigitalOcean-tagged public coding problem, organized only by the stage, topic, difficulty, and recency metadata FastPrep can verify. The broader public catalog also includes 2 system-design exercises.
Onsite practice path
Practice complete solutions and defend the choices behind them. Problems are ranked by repeated public catalog sightings.

01 · Preparation plan
DigitalOcean's practice evidence is infrastructure-oriented: defend an in-process eviction invariant, then scale out identifier storage and lease-based scheduling under failures. 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 LRU Cache Operations to rehearse constant-time recency updates and eviction. Keep the exercise's published contract separate from assumptions about DigitalOcean's current interview process.
Use Design a URL Shortening Service to rehearse sharded identifiers and high-availability reads. Keep the exercise's published contract separate from assumptions about DigitalOcean's current interview process.
Use Design a Machine-Learning Job Scheduler to rehearse scarce compute leases and crash recovery. Keep the exercise's published contract separate from assumptions about DigitalOcean's current interview process.
02 · Broader technical practice
These public DigitalOcean-tagged exercises cover additional technical formats. They are included only when a verified catalog record and a crawlable practice page both exist.
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 practiceDesign a multi-tenant scheduler that allocates scarce compute to training and batch-inference jobs, monitors leases, and recovers safely from worker crashes.
Open practice03 · Evidence boundary
It means practicing transferable implementation, testing, and technical reasoning with public catalog assets FastPrep tags to DigitalOcean. 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 DigitalOcean. Hiring activity, timelines, and market signals remain on the separate hiring-insights page.
The launch review verified 1 coding exercise, 2 system-design exercises (3 total public practice items). The strongest reviewed themes are constant-time recency updates and eviction, sharded identifiers and high-availability reads, scarce compute leases and crash recovery. 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 DigitalOcean. 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.
