Absolutdata Analyst interview questions

I went through written and PI round. These questions were quiet normal on sql and rdbms concepts. It took around 1 day the waiting time too much. The bad thing after my interview was over I was said that they will inform through a telephonic call. But they didn't bother to provide feedback. If we guys are ready to visit your location for interview and waste our complete day, can't you guys spent 5 mins in providing feedback to the candidates, whether they are shortlisted or not?

There was 2 rounds in addition to Group discussion and aptitude test. Questions were quite clear in the aptitude test. Also, people were quite friendly and made us feel comfortable as well
