VMware MTS2 interview questions

It was for entry-level position. Had 2 phone screens (one with manager and one was a technical phone round). Was selected for onsite and there were 5 rounds. 4 of which were technical and 1 was with the manager. The last one was with the recruiter.

I was scheduled an interview on 7/12/2015 at Bangalore office(Kalyani vista) at 10:30 AM. I reached the office on time and met the coordinator. He was friendly and escorted me to the conference room where i was supposed to meet the interviewer. After waiting for almost 30 mins beyond the scheduled time the interviewer did show up and started asking about windows internals / C++ based questions. It went on for about 30 mins. The round went well and the interviewer asked me to wait for the second round. After waiting for about 45 mins in the conference room, another interviewer showed up and he asked few C/C++ questions along with Windows internals and few puzzles. The round went on for about 30 mins and he asked me to wait for the next round. By this time it was already 1 PM. I waited for another half an hour , few of the team guys came in and asked me to join them for lunch. After lunch i came back to conference room and waited for about 2 hours in the conference room. But none showed up, then i called the coordinator, he spoke with the manager to assist me. The manager came in and asked me to wait for 10 more mins so that i can have my 3rd round. I waited for another hour but none showed up. I did call coordinator again, this time manager came running apologizing for all the mess as they have some client meet. And promised me to wait for another 10 mins. But again for another hour none showed up. Finally manager came in and this time he said, he will do the 3rd round. It was already 6 PM and the round was about architecture and system and design. It went on till 7 PM and then he said there will be one more technical round. Another interviewer walked in and this was about core C/C++ and Windows based round and it went on till 8. After this round interviewer said another guy wants to meet me. And he asked me to wait. After about 15 mins, he came in and told me the guy is busy with some conference and will schedule another day. I then left the campus and waited for 2 days but no call from them. I then contacted the HR to know that my profile is impressive but they are looking for some other skills which i do not have. My only question here is if this was the case then why they had to waste my 9 hours in their office. Is it that difficult to assess a candidate skills in 1st or 2nd round??? i felt the interview was just for name sake as they seemed they were doing it for the sake of pleasing someone else. The way they conducted the interview doesn't match their stature.Being such a great company, they have a very irresponsible interviewing panels who do not know why they are interviewing a candidate at first place. For all those who are attending VMware interview at bangalore, please be informed, if they make you wait indefinitely, better walk out of office without informing. Because they really are not serious and just wasting your time.
