Abstract

Over past 20 years programming contests have grown substantial expertise in code assessment, yet it is rarely applied outside the contest settings. This paper presents a case of successful adoption of Olympiad-style code assessment technology in Codility, a commercial web service intended for pre-hire screening of software developers. We discuss correctness and soundness of the automated pre-hire screening, and characterise the class of programming tasks best suited for such application.

Keywords:
