Capgemini Sr Developer interview questions

I had interview today with capgemini. I must say it was worst experience than ever. From beginning, interviewer was treating me rudely. First of all I joined on time then she asked me to rejoin as she said, video getting blur. After rejoin, she asked me to show my ID proof, I showed my digi locker ID (Adhhar card) as I do for every other company's interview, but then she asked me to show physical ID. I somehow convienced her to please proceed with digital photo copy in my device. After 2-3 min of rude comment like you don't know such basic of IT company n all...she proceed with interview. I gave my introduction very politely also explained my tech stack. Then she asked me why you are working on java 21 as you are working in banking & banking should not use latest version (As she don't even know latest version of java is 24). I kept quite. Then she asked me about features of java 21. I explained it along with actual usage in our project. Then she asked me to open online java compiler. I politely asked her that can I open intellij but again she refused by saying it has inbuilt functions (I got surprised). Program was to find unique integers from given number. As she asked me in orally so I confirmed the question to get more clearity. So she got offended that how many time I have to explain this to you & such a basic thing you don't know, you are having 7+ years of experince then also you don't know these things n all. Even though I was very much sure about the solution & could have resolve it in a minute but choose to quit from the interview because of such a rude & unprofessional behaviour. I can reveal her name as well but it doesn't seems good. After the interview I mailed to contact person as well & reported about all such incident happened, & requested to reschedule my interview if possible as I was really interested in this opportunity. I also requested them to go through my interview recording & kindly review it. I heard capgemini is very professional & reputed company in IT. But these kind of people really messing with company's reputation. I request management of company to take strict action against such people or atleast proper training of 'How to treat people & behave like a professional'.
