I interviewed many job applicants throughout my career, and I learned a lot about each person through their resume and cover letter as well as writing samples and answers to difficult questions (esp. behavioral interview questions). If an applicant can't speak and write clearly, they won't get hired by any reputable company. IMO students who attend liberal arts colleges, where more writing is required than in large public universities, fare better in professional companies than do students who excel at taking multiple choice exams. The key to getting a job these days is not so much a factor of where you went to school but more a factor of what job experiences you've had (e.g. internships) and who you know (professional contacts open doors to job leads).
P.S. My personal philosophy about the purpose of college is to teach you how to think. Everyone needs good problem solving skills to succeed in life. And since no one works in a vacuum, everyone also needs excellent communication skills.
