CommScope Sr. Engineer interview questions

This company does not care for its interviewees, they just interview for the sake of it !!! Sometime back I had interviewed for this company, attended a few rounds of interviews, after that they never shared their feedback, never told me if was through ...NOTHING!!!!! just silence . Further , when I contacted the HR regarding the feedback , he put down the phone in the middle of the conversation..... if you are willing to waste your time and have time in abundance go and interview here. because at the end of the the day you will be disrespected and you will never know what you need to improve on.
