Atos SAP LEad Position interview questions

Technical round was almost 30 min telephonic and question was average..second round was horrible ..lasted just less than 5 min and asked some leadership questions and salary pat then updated me that next week Tuesday HR will call for last HR round..that never happened..could not understand where is the problem..salary constraint or something else..realy disturbing..very unprofessional and unethical and no transparent attitude they have shown..
