Raytheon Applied Signal Technology Senior Software Engineer interview questions

I visited their booth at my university's career fair. I talked to one of their Senior managers briefly at the booth, he was impressed and skipped the phone interview and told me that they would be in touch to schedule an onsite interview. A week later, I got a call from them and within days I was at their Sunnyvale location for an onsite interview. The interview lasted for 3 hrs, after which there was a lunch. I think they discussed how that went amongst themselves while I was out at lunch. Right after I talked to their HR rep and got an offer the same day.
