After doing one-too-many interview take-home tests, I decided to collect them
all here, in one convenient place for a prospective hiring manager to see :P

*Why you too should share your interview tests:*

Companies send out standardized tests to hiring candidates because it amortizes
the time-cost of evaluating individual candidates. That is, instead of spending
X hours per candidate evaluating their unique code, instead the give everyone a
standard test and spend just a few minutes to see if the candidate did their
test correctly. This spreads out the cost ("amortizes") over the candidates such
that the business no longer incurs this cost. 

This makes perfect business sense, to be honest. The goo thing is that it works
both ways: businesses can amortize the cost over candidates, and you (the
candidate) can amortize your cost over all the businesses that you interview
with. Simply save all the interview tests you complete in a single place and
share it with hiring managers when they ask for a code sample.
