Worst interview experience. HR called me for interview when I am already holding 2 offers with good salary package. Still she insisted me to attend interview and told me that she will provide higher package.
On the interview venue, she asked me why still you look out for more offers as you are already having offers in hand. I am not sure whether she is dumb or idiotic. Whole interview process was a big mess, except the technical discussion.
