Jivox UI Developer interview questions

They will take five rounds of interview. All rounds are technical. I cleared all the five round of interview, it took almost half day after that HR said you clear all the interviews. Then they try to dominate me how HR people try to do always. Before interview i already told them i need 40% hike otherwise i will not attend the interview, they said OK we will give then only i attend the interview. After all the process completed they are saying we will give only 15-20% hike from your current package. Then i come back from there. Really i hate that HR.
