Is the AI mock interview free?

“A new user who has never done an interview gets one free short session of about three minutes. After that, sessions come with a subscription: the 7-day trial ($2.95) includes 2 ten-minute sessions, the monthly plan 6 per month, the 3-month plan 18 and the 6-month plan 36. Unused sessions do not carry over. See pricing for current plans.”
