Unfathomable smart person stupidity

We had a highly-regarded person come in for a job interview. He's the kind of person that everyone knows who he is if you're in my area of work: he's written multiple books, founded a well-known consulting company, etc etc...the kind of guy whose name you want to have associated with your group.

Man, he f'd his interview day up--and it was so preventable.

All he did was take a phone call at the end of his interview day. He took this call right in the middle of our bullpen (we have a little couch/hang out area)--everyone can hear you--it's clearly not a private or secluded area whatsoever. And what did he decide to loudly discuss with this unknown person on the phone (WHERE WE CAN ALL HEAR YOU):

- Other companies he's interviewing with
- His expectations of the kind of company he wants to work for & commuting preferences
- Cursing multiple times saying things like: "Design firms are bullsh*t--which is kind of ironic because he founded one
- Naming people in the field and talking about their personal lives (and yes, we all know these people even if they're not at my company--our field is small)
- Denigrating two companies by name and saying that they had poor design groups

I mean, really? REALLY? This is what you thought would be appropriate to have a conversation about in the open area where you've been interviewing all day? Did he think this was demonstrating self-awareness and honesty? I was seriously stunned and for the length of his conversation (maybe 20-30 min), just IM'd back and forth with my boss about everything he was saying.

Needless to say, he won't be getting an offer from us.

LUNCHNOODLE--Keep this post in mind. He's actually super interested in your company, I kid you not. He may have even already interviewed with you guys (though I know you have multiple teams that do design, so maybe it's not directly in your line).
