Why Resume Ranking is a Bad Idea?

"Recruiters take 6-seconds on average to read your resume." Though it may not be exactly true, it does manifest the challenge of effective evaluation of candidates. Amazon used a resume ranking system in 2014 to rank top candidates in order to automate the hiring process, until they found out that the engine did not like women. But by 2015, the company realized its new system was not rating candidates for software developer jobs and other technical posts in a gender-neutral way. To understand the problem, we'll cover the baseline of how the model works and dive deeper into what can go wrong and why.
