I read this on the Lovells website:
Applicants to Lovells need the right personality as well as the right qualifications.
You will be happy working in a team yet capable of, and used to, independent action. You will demonstrate ability and desire for lateral thinking and be capable of close attention to detail. Above all, you will have a single-minded ambition to succeed in a top law firm.
As a clerk in a major law firm? Yeah, right!
