Sailotech Software Developer interview questions

There were total 3 rounds, 2 technical and one managerial round. I cleared all the 3 rounds but did not receive any feedback from the HR even after requesting for the feedback multiple times. I stated my expected package upfront before any of the rounds were conducted and yet they told me the package I was requesting was too much at the end of third round. If they were not willing to pay me what I was expecting then why did they have to conduct all the rounds and waste their time and mine as well! Overall very negative experience!
