MSD Senior Manager - Advanced Data and Analytics interview questions

I applied through a referral. A struck-up company with no budget and low salaries. They knew my salary expectation from the beginning. There are 4 rounds of interviews. After every round of interviews, I got positive feedback and cleared all rounds of interviews. The HR and salary discussion round was very pathetic. She is very rude. They should not proceed with the process if they can't offer a salary as per your expectation at the screening round.
