Previously (but for a different type of position IIRC) you were requiring applicants to pay for your program and apply with a cover letter detailing their experience: https://news.ycombinator.com/item?id=34983991 (parent comment now deleted, but you had roughly said that you would not entertain applications from people who had not done this prior step)

For the sake of people reading this, can you clarify if this is something you'll also be requiring of potential "Growth hacker / cofounder" applicants?
