Meanwhile Lockheed told me they're changing the job pay grade, which means posting it to the website and opening it to internal applicants before my resume can be reviewed again (this is after I've been interviewed). Translation: they can't get their paperwork done before Laura goes into labor.
The good news is I finally got to talk to a guy on the Northrop job and find out what I'd be doing. It's better than what I originally interviewed for with them, more software work.
So it looks like it's going to be Northrop. Barring any further paperwork @#$%-ups or nasty traps in the fine print of the offer.
