PwC First interview help



I have a first interview coming up and I just can’t seem to pass these interviews(or most interviews for that matter). The first interview is competency based and so when I get asked a question, I answer the question using the STAR technique. However even using that I still can’t seem to pass the interview(failed my last one with them on what I thought was an alright interview). Can anyone provide me any tips? Do I have to make sure that my answers to the questions covers most/all of PwC’s core compotencies? I just don’t know what I’m doing wrong! :frowning:
