Cleartrip Software Development Engineer -3 interview questions

I gave 7 rounds of interview with cleartrip. All were elimination rounds.1 machine coding + 3 technical rounds. + 2 techno managerial + 1 HR round. After clearing all the rounds with very good feedback in each round. I was called to the office for last managerial round, where all the previous experience and few technical questions were asked. At the end of 7th round i was told my experience and scale at which I worked previously did not match their standard. I was really disappointed in them as they should have checked this at the start itself. If i am able to clear all their tech rounds, why would they say that in the last round. They themselves have no faith in their interview process. Total waste of time. I would highly recommend not to waste their time with this stupid process.
