Would be funny to come into an interview as the candidate and give the employer pre-packaged tasks to complete to evaluate them on, to decide if I as the candidate actually want to work there.
As a candidate, you'd bring less pre-packaged tasks and more questions and things to look out for. When I'm on the other side of the interviewing table, I evaluate the company as much as they evaluate me. Things like "What does it take to succeed at this company?" and "If I'm not meeting expectations, how will I know?" are critical to see if you want to work there.
Anyway, stay tuned!
Where I am right now, I'm pretty happy just turning down the interview if I don't oblige.
