Hello!
First of all, huge congratulations on being invited to the PwC virtual AC - that's an amazing achievement! Whilst I'm not too sure on the specifics of PwC's AC, I can share some general advice when it comes to preparing for a virtual assessment centre, as I completed a few last cycle. I have also quoted some of my previous posts below that discuss other assessment types that might be useful, as I wasn't too sure what is involved in the PwC AC.
Some general tips:
- Prepare the basics: you may have already been doing this, but make sure you understand PwC's values, business areas, and the current market issues that will affect them. You don't need to know absolutely everything (so try not to panic!), but it's good to have an awareness of what PwC does so that you can link this to why you are interested
- For group exercises: usually, the focus of the group exercise isn't actually what you say - it is how you interact and communicate with the others around you. Focus on being collaborative rather than trying to dominate the conversation - I always tried to be neither the quietest nor the loudest (which can be a tricky balance!). I found this particularly challenging for virtual ACs where it can be difficult to get the timing right, but try to listen actively and build on others' ideas. When you do present your part of the group exercise, make sure to clearly explain your reasoning and thought process!
- For interviews: if you are asked competency questions, it's always helpful to have the STAR structure in the back of your mind, and have a few examples ready that show teamwork, problem-solving, and resilience. As part of my preparation for assessment centres, I used to spend an hour or so just noting down all my experiences and what skills / competencies came out of each. This means you aren't desperately racking your brain for examples in the moment!
- Virtual elements: it sounds silly, but make sure that you test your technology beforehand (i.e. WiFi, camera, microphone) and choose a quiet space - I even made sure to let all of my housemates know so that none of them disturbed me. I would make sure that you have water and a notebook nearby, as you never know when you might need to jot something down.
Most importantly, be yourself! Focus on showing how you think and work with others when you are performing at your best, rather than trying to be "perfect" overall. Firms are often looking for potential, not perfection!
Everyone is nervous going into ACs, so you're definitely not alone! You've earned your place there by excelling in the process so far - so just go into it and try your best

Wishing you the best of luck, you've got this! 💪
