Interesting.  For most jobs, there are thousands of people who either a) can do the job or b) can be trained to do the job.  Personality is far more important than technical skills, particularly since you tend to spend 8+ hours a day with your co-workers.  It seems like these types of questions are completely relevant and fair.  No one wants to spends all day working next to an anti-social outcast. Anti-social employees can be a drain on the productivity of the entire organization.

1. Your Attitude Matters Almost as Much as Your Work
You might think that if you do great work, that’s all that matters—but attitude and interpersonal skills can matter a great deal. Healthy organizations have low tolerance for difficult personalities, in part because managing a team can be exhausting, and it gets significantly harder when a team member is resistant to feedback, difficult to work with, or just plain unpleasant.
If you complain frequently, regularly shoot down ideas, or act like the office prima donna, your boss probably considers you a pain to deal with, even if she never says so. That could result in you getting less interesting work assignments, less flexibility, lower raises, and a higher chance of ending up at the top of the list if cuts ever need to be made—yes, even if your work product is stellar. To be clear, that doesn’t mean that you shouldn’t speak up if you disagree or are unhappy. Good managers value input. But if you find yourself resisting more projects than you embrace or if you get feedback that you’re coming across as negative or combative rather than constructive, there’s a problem.

This bit from the What your boss probably wants you to know thread seems pretty relevant to your point.

Quoted:


These are all things I've seen for myself over the past few decades and agree with.  I put on the correct mask every day when I walk through the door of my current employer.  I act the part for my 8 hours.  I guess I'm just frustrated with the expectation that I conform to the norms of thought when I have just as much value as others in terms of output.  My opinions are my business.  What I produce for their business should be their primary concern.

You mean to tell me that being an irritable-moody-loner-basement dweller is not a desirable thing in a corporate culture?  Say it ain't so!!!

Next thing you'll tell me is that bathing is encouraged and maybe even required!
