I think A&O take a significant amount from vac schemes. All the trainees I met at my recent AC had done some sort of VS or A&O First program with the firm and the trainee I was buddied with for the office tour couldn't think of any trainees (that they knew) who hadn't done such schemes. Worth noting I think!
Fair enough, I think A&O are similar to Freshfields in that they have 50 vac scheme places across winter and summer, but 80-90 tcs overall
