Project / Work Assignments

IMPORTANT—make sure you do this.



We will only consider candidates who solve the following small puzzle and supply both the solution and the code that was used to reach it.



It should take the average programmer about 15-20 minutes to do this.



If the candidate is not interested in taking a crack, this job is not a good fit.





Puzzle: The 2010 Census puts populations of 26 largest US metro areas at 18897109, 12828837, 9461105, 6371773, 5965343, 5946800, 5582170, 5564635, 5268860, 4552402, 4335391, 4296250, 4224851, 4192887, 3439809, 3279833, 3095313, 2812896, 2783243, 2710489, 2543482, 2356285, 2226009, 2149127, 2142508, and 2134411.
