Perguntas de entrevista de vagas de Systems Engineer - Level II Datacenter da empresa ADP

strange... first two interviews were basic screening questions. the third interview was a basic techie interview, the fourth interview was more in-depth. Never made it to a fifth interview. The whole interview process spanned almost 2 months. All interviews were within 2 days of their request. AND then it was almost 3 months before they responded back after that.
