An AI Amazon built to automate the hiring process reportedly took a turn for the worse. According to the report, the machine learning algorithm was programmed to sort through resumes and pick out the best candidates for a job. Machine learning algorithms learn from the data they're trained on, and the resumes Amazon fed this algorithm were unintentionally skewed towards male candidates. Naturally, the AI picked up on that, and showed a bias against women's resumes that took some time to discover. Amazon has allegedly abandoned the effort, but not before the AI was used in at least some capacity. Amazon declined to comment on the technology’s challenges, but said the tool "was never used by Amazon recruiters to evaluate candidates." The company did not elaborate further. It did not dispute that recruiters looked at the recommendations generated by the recruiting engine.
