Next cycle you'll get something hopefully! My advice for next cycle is try to apply to more law firms, for instance I applied to 65 and got rejected from most but still secured a VS with one firm...I got the Paul, Weiss PFO but what was really funny to me was that in the email they said, "thank you for your application to the Spring Vacation Scheme" I applied for the Summer Vacation Scheme...
Anyways this is going to be my last cycle - 4 unsuccessful cycles, 0 applications progressed past the first stage. Figured I could overcome my poor A-Levels and first degree's GPA but alas I am the architect of my own demise.
good luck!!
