Sentence 2 stands out from the rest because it does not directly contribute to the theme of a shift in hiring priorities towards soft skills. Sentences 1, 3, 4, and 5 all center around changes in hiring practices, the significance of soft skills, and the response to the pandemic, forming a cohesive narrative.
In contrast, Sentence 2 introduces a broader concept about redefining the ideal candidate without specifically addressing the shift towards prioritizing soft skills. This divergence makes it the anomaly within the context of the paragraph's main focus.
So, the correct option is (B): Companies are shaking off the old definition of an ideal candidate and ditching the idea of looking for the singularly perfect candidate altogether.
