Good idea. The website is slow, even at 1:20 am Pacific. They allow you to import your LinkedIn profile and invite any of your linkedin contacts. They also offer 10% referral bonuses; you get % of your contacts' interview revenue. I can see why the registrations are growing exponentially even if it's invite only.
They evaluate you post-interview on the following:
The company rates you post-interview, and one of the things they rate you on is how seriously you took the interview. So, basically, they can't weed out people just doing it for the money, as long as the person takes the interview seriously and acts professionally. Regardless, I think this is a good idea, it will definitely work as a self-funded company.
They evaluate you post-interview on the following:
---% - you took the interview seriously
---% - you were on time for the interview
---% - your profile was accurate
---% - they'd recommend you to others
