RTX Software Engineer interview questions

I was contacted by email to set up an interview with the department manager. The day of the interview, the manager was unavailable due to "circumstances beyond his control." Instead, I was interviewed by 2 other engineers and a lower-level manager. I was told I would be contacted one way or the other in about a week. Two weeks later, hearing nothing, I called the manager I interviewed with. He directed me to an HR rep, who routed me to another HR rep, who sent me an email 2 days later saying someone else already got the job.

Went through phone interview where the things on my resume were discussed and some basic questions on object oriented principles were asked. After that I was invited to an onsite interview with 3 interviewers in which a slightly more extensive version of the phone interview took place.
