TestGorilla is a B2B hiring tool — companies pay for it to screen candidates. If you've been sent a TestGorilla assessment during a job application, you've experienced it from the candidate side: a timed test, possibly with webcam proctoring, and results that go directly to the employer. You never see your own score.
Skeelzy is the opposite model: you take the quiz yourself, you see your score, and it appears on your resume. The audience isn't an employer assessing you — it's every recruiter who opens your resume going forward.
The B2B vs B2C skills testing gap
The developer skills testing market has a gap. Tools like TestGorilla, HackerRank, and Codility are built for employers who want to screen candidates efficiently. They're good at that job. But they leave the candidate with nothing: you take the test, the employer keeps the result, and you start from zero with the next employer.
Skeelzy is built for the developer who wants to prove their skills before they even start applying — so that the first filter isn't "pass this employer's test," it's "they can already see on my resume that I passed."
Why owning your score matters
When a TestGorilla result sits in an employer's ATS, it's useful exactly once — for that employer's decision. If you don't get the job, that score helped no one.
When a Skeelzy score sits on your public resume, it works for every application you make, indefinitely. Every recruiter who opens your resume sees the verified score. Every application you submit is backed by it. The effort of taking the quiz compounds across every job search you'll ever do.
There's also a preparation benefit. Taking a Skeelzy quiz before applying tells you exactly where your knowledge gaps are — before an employer's test reveals them under time pressure. Developers who know their weak spots before the interview can address them. Developers who discover their weak spots during the interview cannot.
When you'll encounter TestGorilla vs Skeelzy
You'll encounter TestGorilla (and similar tools like HackerRank, Codility, or CodinGame) as an employer-sent assessment during an application process. You have no choice about taking it — it's part of the funnel.
You use Skeelzy proactively, before applying. The goal is to show up to that funnel with verified evidence already on your resume — so the employer's own assessment is confirmation of what they already had reason to believe, not a discovery.
Used together: take Skeelzy quizzes to benchmark and verify your skills. Add the scores to your resume. When an employer sends you a TestGorilla or HackerRank assessment, you'll be walking in with accurate self-knowledge rather than hoping for the best.
