Since Google is supposed to buy ITA as soon as government regulators approve the deal (don't know when that will be, my guess is late fall / early winter of this year), this is also a way to get into Google, in case you happen to want to work for Google.
Wanna? If you have questions leave a comment. Apply here, and for "How were you referred to ITA?" choose "Employee Referral" and put my name in (and also leave a comment or email me), and I'll get someone to look at it quickly.
Edit: "Apply here" link updated from original post.
