Why mock interview credits are separate
Live mock interviews — AI or human — are run-cost heavy. Sell them as standalone credits so you only pay for what you use. Credits stack across packs and never expire.
Fast Iteration
AI sessions cost a fraction of human ones — perfect for drilling format and reps before the real round.
Real Engineers
Human sessions pair you with engineers from top-tier companies for nuanced feedback no AI can match.
No Expiry
Credits sit in your account until you use them — no monthly reset, no subscription required.
Frequently Asked Questions
Do mock-interview credits expire?
No. They sit in your account until you use them. There's no monthly reset and no expiry date — applies to both AI and 1-1 human interview credits.
What's the difference between AI and 1-1 human interviews?
AI interviews are 30-minute voice sessions with a Claude-powered interviewer — instant feedback, runs at any hour. 1-1 human interviews are scheduled 60-minute sessions with a senior engineer from a top company, with detailed written feedback afterward.
Can I use mock credits on a free account?
Yes. Mock-interview credits — AI or human — are sold separately from our subscriptions. You can buy a pack without ever subscribing.
How do I schedule a 1-1 human interview after buying a pack?
After purchase, you'll receive an email with a scheduling link. Pick a slot, share your resume + target role, and we match you with an engineer specialised in that area.
Can I combine multiple packs?
Yes. Every purchase ADDS to your existing balance for that credit type. Buy a Sprint today, a Marathon later — AI credits stack. Same for human-interview credits.
What if my interview fails halfway?
AI sessions where you didn't get a chance to finish: email customer-care@phantomcodeai.com (or raise a request from the chat bubble on the bottom right) and we'll restore the credit if it broke. Human sessions: cancel 24h+ in advance for a full credit refund.
