HARMAN Software Engineer interview questions

I got call from Harman recruitment team for .Net developer + angular js . The interview as on Saturday, they scheduled my interview 11am. I reached there before time. There was 3 rounds , 1st was regarding angular js , 2nd was on .Net and 3rd is manager round. I have waited there for 2 hrs then i got call for 1st round, there they asked normal questions related angular js. After that for 2nd round I have waited for another 2 hrs, there the interviewer asked me only 3 technical questions and i gave correct answer of all 3. But after waiting another 1hr the Recruitment manager came and told me that i was not suitable for the job as my 2nd round was not good. I don't know why they call us if they don't want to hire ! Complete waste of time. Please go through the candidate's resume before calling them. It was really very bad experience even after given all correct answer if you are not selected !!

Most sorted one of all the interviews I have attended till now.It was very well organized.An mcq test was there of average difficulty. Then 2 technical rounds and in the end a HR round.
