Here are some resources that I've assembled over the years:

• Econ Job Market Interview Cheat Sheet: For those on the Econ Job Market, this nifty little excel file, created by Ryan Sandler.
  
  
• Scraping for economists:  For those looking to start learning some basic scraping tools (combing data off of websites), this packet has a write-up and tutorial with sample code.  (Created jointly with Ryan Sandler.)
