Deutsche Bank interview questions

Firstly , they have OA which consist of 3 questions I was able to solve all of them properly . Then i got shortlisted for the interview .In my clg at IIT BHU Varanasi we have its interview in day 1st of December . According to me , the results are unfair as my interview went very smooth and very good. My panel members include maam and a sir . Firstly , as i went she asked me about my high cpi then went staright to my intern and also in intern she asked me one difficult question as well ,I answered her properly and smoothly as I was aware of that thing . Then sir asked me about my projects , a dsa questions , OS,DBMS and i answered 90% of his questions as well . But at the end they rejected me ,also i got to know that my panel has taken nobody . But there the people who dont know C of coding got shortlisted and many of them really dont know anything .

The interview was well structured and divided into two parts: the first with different developers, and the second with members of another team. First one was related to qa and python, 2nd one was related to frontend.
