I am looking into Walden University. I want to get a masters there but want to know how HR people look at these schools.

That depends on the interviewer and/or the committee who decides whether they hire you. Some care where you get your degree, others don't.

I believe if a candidate can do the job and he seems like he'd be a pleasure to be around, then I'll extend an offer. Where he went to college, or whether he even went is irrelevant to me.

So again I say, it all depends on the person interviewing you.

It all depends on what you want to get a Masters in.
