Firstly HR round and second round is technical give to task for converting the page HTML I did complete my task with 100%. after that, I clear the all-round we discuss the salary I'm ready for the same package because I learning to react js but the next I call HR for asking about my interview feedback, she answered I thought your salary it's 20k per month but i clearly the first HR round my salary is 28K per month she's also mentioned in my resume. I can't understand you do not agree with my same package, so why you are given the technical task this is a waste of time please HR firstly clear all doubts after that we proceed to the next round. Thank you
