Practice for Job Fair / Thanksgiving

This is the last job prep day before two important interrogative events: a job fair December 5th, and American Thanksgiving, November 28. We're going to practice responding to questions in pairs. Explicitly state who you are before starting to ask questions - you'd say different things to your uncle over mashed potatoes than you would to an engineer at the job fair from Etsy.

We'll also share solutions to interview questions / programming problems we're finding tough - I want to check in with some people on recursion in particular.

Here's a script to choose questions from:

• What's Hacker School? (Try telling this to a skeptical interviewer - it's not your job to defend Hacker School! Just to tell your story)
• What language did they teach you there?
