GE Aerospace interview questions

Emailed me after career fair to set up an interview. Thirty minute behavioral interview with one of the recruiters. The interview was more conversation than an interview. After the interview, she contacted me with an offer about 3 days later.

I have been contacted by phone twice by the HR department. The process was going well and they forwarded my resume to the hiring manager, who would call me "this week". I contacted the HR by the end of the week and was informed that the hiring manager would call me "next week". By the end of the second week the hiring manager left for holidays for two weeks. Then by the date he should come back the HR simply kept blaming the hiring manager for not answering each week and eventually stopped answering my e-mails.
