RTX interview questions

I visited them during a career fair on campus. They told me to apply online and to the university recruiting site. After this process, I was invited for an interview on campus. The whole process was very quick, and after the on campus interview the information was passed to the hiring manager.

HR contacted me a little over a month after applying for the position. They wanted to setup a phone interview with the hiring manager. I was very flexible with my schedule, so I made them aware of that (bad mistake). They gave me a 2 day window when he would call me... I never received a call from him and until this day I have not heard back from them. The position is still open so is not like they cancelled it (as far as I can tell). I feel it is very unprofessional to not even call/e-mail to apologize or at least explain what was going on. Not only that, but I called the HR representative the first day I was waiting for the phone call from the hiring manager. She did not answer, so I left a voice-mail asking for a call back so I could ask a quick question. She did not return my call, so I had to call back the next day. When she answered, all she said was: “Oh yeah, I got your voice-mail yesterday… did you have a question?”. Not sure if other people had problems with them, but my overall experience with them has been extremely negative. Hopefully I am just a fluke and normally they are not this rude to their candidates. Otherwise, I hope someone (with authority) from the company reads this and does something about it.
