ANB Solutions Co. Pvt. Ltd. interview questions

I was shortlisted for interview round for VAPT Profile. Round 1: Pure technical interview where I answered almost 85% of questions correctly. Seems the one who was taking the interview on was not having proper knowledge. Then I was told that I'm not shortlisted and the interviewer have negative feedback. After couple of days again I got call that your round 1 is cleared and we will take client round for VAPT profile and the JD shared with me was also for VAPT role only. Round 2 (Client Round): Asked all the questions related to VAPT, Encryptions, Ethical Hacking and ISO 27001 and i answers almost all of his questions correctly at the end feedback was also give that I'm good candidate. Now when I took the follow-up on interview status, HR is informing me that I've no experience of Audit and the reason client have reject your profile although the interview was for the VAPT role and the JD was also shared with me. Not sure if HR themselves are awareof the candidate they are looking for and have knowledge of the JD they are circulating .
