How this tool works
The OA Randomizer pulls from LeakCode's live database of Online Assessment questions reported by candidates at FAANG and other top tech companies. Every question is tagged with company, role type, round type (OA), difficulty, and topic — so you can either go fully random or narrow to exactly what you're preparing for.
Click "Another" to load a fresh question instantly via HTMX — no page reload. Use the company dropdown to focus on a specific employer like Google, Amazon, Meta, or Microsoft. Use the topic dropdown to drill into algorithmic areas like dynamic programming, binary trees, or graphs.
Why use a randomizer for OA prep?
The most common mistake in OA prep is "tag-drilling" — practicing only problems labeled with a specific topic you expect, then freezing when the real OA presents a problem you can't immediately categorize. Real Online Assessments rarely announce the topic. You get a problem, a timer, and nothing else.
A randomizer forces you to cold-start: read the problem, figure out the pattern, then solve. That's the actual skill being tested. Candidates who do random-question sets in their final prep week consistently report fewer surprises on OA day than those who grind company-specific lists linearly.
The questions in this tool are real — reported by candidates who actually sat the OA. This isn't a curated practice set built by an instructor. It's raw signal from the interview process itself.
Frequently asked questions
Are these questions up to date for 2026?

The OA database covers 80+ companies including Google, Amazon, Meta, Microsoft, Apple, Stripe, Netflix, OpenAI, Bloomberg, and hundreds of mid-market and startup employers. Use the company dropdown to see exactly which companies have enough OA data to filter on.
