Perguntas de entrevista de vagas de Technical Project Manager/Migration PM da empresa EPAM Systems

For an Technical Project Manager there were 4 rounds. First Round - Pure Technical one hour Second Round- Pure Technical one hour Third Round - Pure Technical one hour Fourth Round - Delivery Manger Round Pure Technical one hour . So finally you expect to be offered the role but no they rejected saying they need more technical people. what was left in first 3 rounds if someone is not technical how were those rounds cleared? And if someone has cleared everything why give vague ways to reject candidate. If you need a manager conduct accordingly but if you need an architect then dont mention Manager in the JD
