G+D Netcetera Senior Software Engineer interview questions

The interview was a nightmare. The interviewer was too arrogant and appointed an interview for 4 hours in which he asked deep technical questions that were even out of the domain that I was applying for. I was also asked if I am able to develop a whole CRUD application in Java without using any internet or reference. I felt frustrated because they spent 4 hours of my time and after a week they sent me an email that they don't think that I am senior and they are willing to offer me a intermediate position with 700 Euros net salary. I am working software development for 7 years and I have been developing some big projects. The overall experience was really unpleasant and I wish no one to have that interview again.
