PwC UK recruitment - experienced hires Watch
The big4 is a numbers game. Every individual team which makes up the big4 will have a budget (even within audit and assurance, you'll have for example TMT or LTT etc. which will have their own budget and headcount). They may be interviewing other candidates/waiting to hear back on offers they made/waiting on a client tender to see what numbers they need. Be patient, if the feedback was positive you'll likely fit in but it might take longer than you expect. When was the interview? I'd follow up on Tuesday with your HR contact. 'hi xxx, I really enjoyed my interview experience with x last week. I just wanted to follow up regarding my application and when I will be updated on its status?'
