"Companies reveal their true colors during the recruiting and selection process" says author Jon Picoult. If they are really serious about treating employees well, that will be evident to applicants. Companies that prove unresponsive or unreliable are likely to be poor places to work. On the other hand, per a Stanford Business School case study, companies that treat job applicants very well are likely to get the best people, and to have the best financial results.
Additionally, forward-thinking companies recognize that job applicants are also consumers. Alienating them during the hiring process is likely to translate into lost sales, compounded by the unfavorable word-of-worth that is bound to result.
