Wells fargo came to our campus, During OA they asked three question

1. Something related to regex.
2. second question was just another variation of knapsack problem
3. related to sql query

Duration: 1hr
I solved all the questions in 25minutes and got shortlisted

Round 2: Technical Interview: online

Questions were around resume, On the projects I have done, since most of my work was related to frontend, so mostly on that only,

Few questions on OOPS. and no coding question for me.
but this was interviewer dependent,One of friends got dp+string question which was medium-hard
It lasted for around an hour.

Round 3: Technical Interview+HR: ofline

In this they asked about my resume again, about my projects again,
than after 10 minutes discusion on that, I got question on normalisation.
I explained what it is and it's type. Then she asked me to think of an example and normalize it.

this lasted for 15-20minutes;
