FAQ
Can I cancel anytime?+
Yes. Month-to-month. Cancel from your billing page; access continues through the current period.
What does the founding price get me?+
$49/month locked in for 12 months from signup. After that, you renew at whatever the current price is. The founding rate is only offered to the first 100 subscribers; after that, new sign-ups pay $79/month from day one.
What happens if my target company isn't covered?+
Anthropic and OpenAI are live now. Google, Meta, Stripe, and Databricks are queued. Email support to vote for the next company.
How fresh is the data?+
Question banks are refreshed monthly from new candidate reports. Each question shows when it was last reported (e.g., 'Last reported April 2026').
What does 'verified report' mean for the contribute-back program?+
Reports are auto-graded by an LLM for structure and detail. Reports scoring 80+ are accepted automatically; 30–80 go to manual review; below 30 are rejected. Top contributors can opt into LinkedIn or recruiter-email verification for higher payouts.
Why is there a monthly cash cap, and how does it work?+
To keep the contribute-back program sustainable as the community grows, full cash payouts cover the first 30 standard reports + 10 brand-new questions each month, applied first-come-first-served. Reports beyond that earn 50% of the cash amount but still earn 100% of the equivalent Pro credit. Most contributors take the Pro-credit option anyway — it's faster to claim and locks in continued access to the catalog. The cap resets on the first of each month.
Is this legal? Won't companies be upset?+
The same model as Glassdoor / Levels.fyi / 1point3acres. Candidates own their experiences and can describe them. We anonymize and never name individual interviewers. We honor takedown requests for legitimate concerns.
