Mphasis AWS/DevOps Engineer interview questions

They started saying that , there will be 3 round. 2 technical 1 managerial. First round , They asked question from every topic mentioned in my CV. I was informed I have cleared the round. 2nd round, Question came more from depth of my technical skills. 3rd round I was told , its managerial not technical. But this time it was long 1 hour deep technical interview on docker kubernetes and Jenkins. Finally they said I have cleared all round. Now this time there wil be another round which wil be managerial. I jump into the managerial call , the guy asked me few stuff about me and what I knw. The interview took place hardly for 10 min. Then after I 2 consecutive follow up about the feedback of my interview. They said u hav not cleared last round. I am like this company is mad or what ?? On the basis of 10 min non technical discussion they decided to not proceed with me. Just wasted my golden time of my life.
