Why recruiters join

Higher placement rates

Candidates who practice system design under real conditions perform better in SD rounds. Fewer failed finals means more placements.

Differentiate your pipeline

Offer SD prep as a value-add. Candidates remember recruiters who helped them prepare, not just ones who passed them through.

Earn referral commissions

Get 20% of every subscription your candidates sign up for. Monthly or annual — you earn either way.

How it works

1

Sign up for a free recruiter account

Takes 30 seconds. You get a unique referral link tied to your agency.

2

Share with candidates

When you place a candidate into an interview loop, send them your referral link. They get a free challenge to try — no friction.

3

They practice under pressure

Timed challenges, real diagramming, reference answers. The gap most candidates have is practice, not knowledge.

4

You earn when they upgrade

If your candidate subscribes to Pro ($19/mo or $99/yr), you earn 20% commission. Paid out monthly.

What your candidates get

  • 27 system design challenges (URL Shortener, Twitter Feed, Uber, etc.)
  • Timed practice with real countdown — simulates interview pressure
  • Excalidraw canvas for diagramming — like a real whiteboard
  • Reference answer keys from engineers who passed at top companies
  • 1 free challenge, no credit card — they can try before committing

Common questions

How much do I earn per referral?

20% of whatever the candidate pays. That's $3.80/mo for monthly subscribers or $19.80 one-time for annual ($99/yr). Monthly commissions recur for 12 months.

How do I get paid?

After you sign up, you'll connect a payout account. Payouts happen monthly for all earned commissions.

How long does my referral link stay active?

90 days. If a candidate clicks your link and subscribes within 90 days, you get credit — even if they don't sign up immediately.

Is there a cost to join?

No. The referral program is free. You create a regular account, register as a recruiter, and start sharing your link.

Can I see which candidates signed up?

You can see aggregated stats — clicks, sign-ups, and conversions — on your dashboard. Individual candidate identities are not shared for privacy reasons.
