Wells Fargo Internship interview questions

I had a first round interest which leads to a virtual super day interview. The first round interview was 30 minutes and consisted of both behavioral and technical questions. The interviewers were nice and conversational.

The interviewer was very professional and courteous.He made me comfortable and asked me to introduce myself and my interests. He discussed my projects before jumping into dsa and then he began asking oops. After that he began asking dbms and then finally asked me oops
