Last year I had my resume submitted by a third-party recruiter for a role there. My resume was rejected out-of-hand by the hiring manager because the companies/customers I had worked for were "too enterprisey" (i.e. I had only worked for government contractors at that point). The "too enterprisey" quote came directly from the recruiter. I suppose he could have been blowing smoke up my ass, but I don't think he would have said that if he was.
Ah, okay. Sounds like they were trying to focus on people with a specific type of experience and not blacklisting people based on a specific employer or anything.
