What is the selection criteria ? I feel many folks who have flexible jobs (waiter, uber driver, etc) would love to join your program, work on assignments for a say 5 hours and do part time work rest of the time.
We like to see some evidence that they want to do software development. E.g. they have some small projects or they've been doing some self-study or courses. We have several uber drivers in our cohort right now actually.
