Thanks Axel,Congratulations!
The second stage is the final one and I did it online too! It consists of two interviews. The first one is based on your CV, your experiences and your motivations. The second interview is an article based interview and it is pretty straightforward. You then have a discussion with two partners about the article. I really enjoyed this process, it was really fun and engaging. I would not worry too much!
I prepared by discussing unseen article with friends two weeks before the interview and it worked out for me!
Good luck with the process!!
regarding the CV questions- are they the same as those asked by grad rec in the first interview e.g. why commercial law, why Gibson Dunn or more in-depth/specific? Also do they ask any competency or situational questions? and with regard to the article interview, do they ask you to summarise it and/or ask you questions about its contents?
