OneFin Integration Engineer interview questions

Even knowing I am from a Java background, they took the interview, and they have not rejected me until the HR round. After completing all the rounds, they sent the rejection mail. In HR, they used to ask aptitude questions, which feels annoying after attending all the technical and managerial rounds. If they were supposed to reject me, they should not have shortlisted the profile. I came from almost 300 km to attend the interview and was later rejected. Please, if you require a candidate whose profile matches your respective job role, then only shortlist those candidates. Simply don't waste others' time.

First i had to clear the aptitude test, After clearing the aptitude test , I was shortlisted for 1st technical interview, then I was shortlisted for 2nd technical interview, I couldn't clear the 2nd technical round
