Perguntas de entrevista de vagas de Engineer Systems Design & Strategy da empresa T-Mobile

I was contacted from the HR representative 3-4 days after submitting my resume online. In general very kind and professional. After the first phone screening I went through 3 interviews: hiring manager and the team, sr director and the last was with vice president. I didn't get any update after the last interview and my status in the portal was: "Your interview has been completed, we will update you soon". The first time I contacted HR they didn't reply back. After one month I decided to contact them again to know the status and finally got an answer that I wasn't selected for the role. The official refusal through the portal was after 4 months.
