It was easy until it was not , I prepared for the aptitude and it is one of the most hard aptitude exam. I did great and was shortlisted for the next round that was Technical. I solved most of the questions easily and I qualified . In the interview round day , I had a lot of things going on , project submission in college , professors making me go here and there to get things signed and I had Goldman Sachs interview lined up but like no one really cared. So after a rigorous day , I went in the zoom call for the interview , it were some basic dsa questions but as the interviewer was not really cooperative I messed up on one of them.
