During a hiring process at TechGenius Inc., the recruitment team, led by manager Sarah, faces several challenges. First, Sarah tends to favor candidates from her alma mater, assuming they possess high competence. During interviews, she notices that she often forms an impression of a candidate's suitability based on how they're dressed, allowing this single quality to influence her overall evaluation. Additionally, she finds herself overly influenced by the first impression the candidates make, remembering this more than the interview itself. In making final decisions, Sarah relies heavily on choosing candidates based on how easily she recalls their responses, noting that in her past experiences, memorable candidates usually performed the best. In the scenario, how many biases is Sarah falling victim to?
