I know it's strange, but I think my fav part of the tool they offer is the research worksheet. I have looked at job openings in several tech companies I'm interested in, but I'm confused on which company is which in what they have to offer and the benefits and area, etc. Now that I have the research worksheets, I am going to methodically look through the tech companies that interest me and then compare the worksheets to find out which ones I am most interested in interviewing for. Great tool!
