I reached the anti-climactic end of the Google foobar challenge. Quite unfortunate. Last night, I was working on a level 3 problem (spring_cleaning). I had 4 of 5 test cases passing and, fast forward a day, had a good hunch idea on why the last test case was failing.
I found out after the fact that Google was using this challenge as a recruiting tool. Brilliant! I honestly had no idea. I am not sure how it works, but I would assume that breaking level 5 in the predefined period of time might indicate an exceptional computer scientist - at which point they'd engage their army of recruiters :P I am humbled by those that can pull that off.
Tomorrow, I will be participating in Qualcomm's (my employer) first ever Data Mining Competition. I'll spend the rest of the evening working on CS100.1x in preparation.
