Domande di colloquio per PL/SQL Developer presso MetricStream

I was interviewed with MetricStream in the month of December 2018. The position was for PL/SQL developer. There were total 4 rounds of interview. Two technical, then managerial followed by HR. After the complete process with positive remarks the final results were negative. Whole day got wasted. It was really disappointing interview experience. Although belonging from PL/SQL domain, questions were asked from Java.
