Cockroach Labs has implemented strategies to combat unconscious bias in their hiring process. They have removed resumes from interviews and replaced them with experience levels, thesis focus for candidates with PhDs, and current year in school for interns. This approach helps mitigate biases such as affinity bias, halo/horn bias, and similarity bias. The company prepares both the candidate and interviewer for this process to ensure a fair and effective evaluation of skills required for the job.
