For anyone doing the Allen & Overy assessment centre:
I have just found out from the recruiters that they have enough offers for everyone who gets a WVS to have a TC and for the past 5 years, there has been a 100% retention from WVS and there are no more assessments/ interviews after the AC to get the scheme, therefore now that I have "an almost" TC, here is the advice I would give for anyone who has an upcoming A&O AC. Bear in mind the AC is 5 hours long online with only 3 breaks so that is why we don't have further assessments because it is very intense. Anyways, hope this helps!
1) Make sure to look out for key info in the case study and do not waste time reading the whole extract. There were only 3 questions for the case study and the questions specifically say "go to section e or read section f". It's really tempting to read everything but you must focus solely on the questions and answers.
2) Have a notebook nearby to write down your answer because you'll have to present your answers to the three questions for the case study and that presentation should be 15 minutes long ideally. Having a notebook to jot down things will be important because after the presentation, the interviewer will test your comprehension of the rest of the extract.
3) Research common legal solutions for clients. Basically, make sure for the case study exercise that you know what warranties and indemnities are and make sure you suggest them as solutions. (Just do it, the trainees on LinkedIN told me to do so and here I am so it works lol). Go on Investiopedia for research warranties and indemnities so you understand them. Also, learn about balance sheets because one of the sources for the case study is a balance sheet and you want to ensure that you can read a balance sheet.
4) Have a calculator. The second case study question is a mathematical question which can only be done via a calculator. You must ensure that you explain your working out when presenting. Don't worry about getting the answer wrong. I got it wrong lol. But you must explain your working out and the interviewer will go through it with you, just make sure to demonstrate that you understand where you went wrong.
5) Have a cup of water to sip in case you get nervous so you can take a moment to compose yourself.
6) For the written exercise, there is no technique. Just write clearly and concisely with a good structure e.g. firstly, secondly, lastly.
7) For the scenario based interview, make sure to fully explain yourself and at the end when you ask questions, don't ask boring generic questions only like "why law?", if the interviewer seems kind and accepting, feel free to ask deeper questions like "if you were a trainee again, what advice would you have wanted to hear before starting a training contract at Allen & Overy?"
8) It's a very long process, mine was 4 hours and 45 minutes in total. Make sure your wifi and mic work and remain calm, you got this!
9) Reach out to trainees on LinkedIN for tips, they're really forthcoming!
