Credgenics Python Developer interview questions

Two Technical rounds of interview and then salary discussion with recruiter itself. I cleared both tech rounds. before the interview itself the recruiter asked how much i ctc i am expecting i told 17-19 lpa. After clearing the interview she started bargaining like vegetable market. I was holding offer of 16 lpa which i informed her before, she is like we cant give you more than 13 lpa, we had an internal discussion after your interviews this is what we agreed the panels. I was like why did you wasted my time then when you have not had the budget why did you went ahead with my interview. why anyone will settle for package which is less than he has the offer. Chindi company it is.. dont fall for it
