Saiva Consultants interview questions

There are 4 rounds and all are face to face. They call you 2 to 3 times to come office for different rounds as no one day interview will be done . As in 1st round only I told them about my expectations and my last salary then also they took my all rounds and tell me to come again for other round. In the end I director round is done in which he said he can't provide me the salary which was my last salary also 😂 this is the level of company as I didn't expect higher salary then also. They are expecting me to come in less salary then my last one even I told them in 1st round only .just wasted my time.
