Mapprr Software Developer interview questions

This happened in May 2019. They called me for face to face. After going, they made me wait for 3 hours. There was a lady probably the CEO mother who came around to just see me thru the mirror and the later went inside. They took the interview for 15min and asked to leave. I didn't get any revert from them for a long time though i tried to reach them for checking my status. finally, after 12 days they answered my call and informed me that they cannot afford the pay I am asking them which was conveyed by me during the first HR round.
