Collins Aerospace interview questions

I have very bad experience in this company Cleared all rounds( 2) of interview but after HR interview there is no feedback.I sent couple of email but there is no response . such a big company this kind of unprofessional attitude really disppointed . HR not enough mature to deal with candidates. Plz don't play with candidate emotion and time.

Handed my CV in and then had a call with a developer. After the call was invited to an interview with a couple of developers. Interview went well and process was great up until this point. After interviewing, I didn't hear back from anyone until I enquired a couple of weeks later. Quickly after my email I was given an update and rejection. I followed up asking politely for some feedback, but didn't receive any feedback nor an update. I was pretty disappointed with this because as a fresh graduate I think it's important to grow and learn from failures such as this.
