Net Solutions Lead UI/User Experience Designer interview questions

Have gone through various round of interviews, cleared all interviews, got selected and then just kept on hold for weeks and declined the offer at last. They gave me the reason that my expected CTC is high, if so, they knew about my expectations from first day, then why to waste my time in giving the interviews and tests. They have said that I got selected first but when I kept asking again and again for the offer, they didn’t responded for weeks and finally declined my application.
