Why is InterviewOS free?
We've seen too many talented developers miss out on great opportunities because they couldn't afford premium interview prep platforms. InterviewOS was born from a simple belief: your ability to prepare should never depend on your wallet. Every feature is free because every developer deserves an equal shot at their dream job.
Frequently asked questions
Is InterviewOS really 100% free?
Yes, completely. Every single feature — DSA patterns, frontend modules, the Studio IDE, study plans, progress tracking, all 300+ problems — is free. No trials, no hidden tiers, no credit card required. Ever.
Why is it free? What's the catch?
There is no catch. InterviewOS was built with one mission: to make high-quality interview preparation accessible to every developer, regardless of their financial situation. We believe preparation resources should not be behind a paywall.
Will you add paid features in the future?
We have no plans to put any core features behind a paywall. If we ever introduce optional extras (like premium mentoring or mock interviews), all existing features will remain 100% free forever.
Do I need to create an account?
You can browse the platform without an account. Creating a free account unlocks progress tracking, bookmarks, and a personalized dashboard so you can pick up where you left off.
How can I support InterviewOS?
The best way to support us is by using the platform, sharing it with friends preparing for interviews, and giving us feedback. If you land your dream job, drop us a message — that's all the payment we need!
How does InterviewOS compare to paid platforms?
InterviewOS offers structured DSA patterns, a full frontend track, an in-browser IDE, and curated problems — features that paid platforms charge $20–$50/month for. We provide all of it for free with the same (or better) quality.
