Vencore Global Info Solution interview questions

I got a mail from hr.then I came for interview 1st round-technical written 2nd- technical f2f Last Hr round they asked 20000 INR as i was very needy so hr again nd again asking are you able to pay 20000 , she was pushing me unless i said i can't. They they Said this is company policy.I got selected but not able to join due to money problem .

The interview started with a test and then a technical round followed by a HR interview. I completed all the rounds but the HR she asked me for 20k amount to join the company. So I think its fake because I told them directly I will not be able to pay the amount. So, they didn't gave me the job. I cleared the interview but I didnt got the job offer because I couldn't pay the amount.
