Tech9 .NET Developer interview questions

First, they give you Technical online assessment to complete. I cleared that test with a good percentage. Then I got mail from CEO regarding Expected CTC, Notice period etc. I give all the details. After 2 weeks I never heard back from him. I followed up 2 times, then he scheduled my telephonic interview. Before 1 min of the interview, I got mail that he needs to head out for the meeting. Then he rescheduled my interview next week. Again next week on the call he asks me to reschedule in next week. Never heard back from him till now. Now I saw that Position is closed. Really disappointing experience.
