I applied through university. And I didn't get any interview invitation. PwC only interviews people who are on referral lists. So, if you want to apply for PwC, try your best to build connection with people inside the firm
J'ai postulé via un établissement d'enseignement supérieur ou universitaire. J'ai passé un entretien chez PwC
Entretien
30 min for each person，usually there are behavior questions. the interviews are usually senior managers or partners，sometimes HR will join too. One on one interviews. They are all very nice，so do not worry，just try your best，be sure to prepare as much as you can.
