MTAP Technologies interview questions

There were 3 rounds. 2 Technical and 1 managerial. Interviewer informed me that she is on the another too call with client, but her behaviour was good. HR team is very unprofessional. at the beginning they asked me about my expectation. I told my expectation and she said it's okay. after clearing all the round another HR called me and said I can only offer 10% hike to you because there is another candidate who is ready to join with less package than me they are doing this unprofessional thing. so please before proceeding please confirm about your ECTC.

2 Rounds of interview has been taken. 1st round was coding round. In 1st round they ask 2 coding questions to solve on any ide. 2nd round was related to my project.
