CommScope Staff Software Engineer interview questions

There were two panelists who took my interview and had given a coding problem which I had executed and they had asked some java regular interview questions. I believe the interview went well. But the hiring team did not reach back with an outcome and I sent follow up emails thrice up to a month and they never bothered to update the outcome then I sent them another follow up email making them to understand that I had invested my time in giving interview I had taken a half day leave to give this interview. I am not happy with the kind of treatment this company hiring team does with candidates.
