You're right. This is absurd pricing, both from the perspective of what expertise at this level costs, and the value the service intends to generate. A 1-hour interview in this service is ~0.08% of first year salary. A recruiter takes 15-25%.

It's hard to take this seriously. It's one of those things where, if it worked, you'd have to assume the owners would be using it to print infinite money. At these prices, there's a positive ROI to having their panel of experts interview random people off the street.

It's also not clear what the price tiers mean. "Junior/Senior/Management" --- is that the skill level of the interviewer?
