They are totally unprofessional , They don't know how to behave with candidate. They are thinking we bengalis know everything except we other people is dump. If they know personally then only they can call you for further interview. They will give you a task which is not completed by them. They will give stupid IQ test which is mention in google or any book. If they don't know about the other company they will tell you are fake candidate. they don't have proper knowledge.
