Great; they really do question you but it was an enjoyable experience. They go through your CV, ask you about your former experiences, and what inspired you to become a lawyer. They go through the problem question with you, and test your commercial awareness skills, so I would really recommend reading up/listening to podcasts to prepare.
I applied online. I interviewed at Sinclairslaw (London, England)
Interview
Good interview, professional and honest conversation. Lots of information exchanged which provided an insight to the work involved. Conversation was also interesting and lighthearted which helped build rapport. Accepted the role when offered.
