Are you referring to the legal cheek fair?
I shortlisted two law firms to sit through, the trainee who was on the panel for the first firm was close to useless - people would be asking him questions and he would literally give the most generic answer of “yes…. There’s also loads of info on our website” to every question, he sounded like he knew nothing about the firm and it was hard to extrapolate any information from that specific law firm.
The second firm I sat through, was slightly better. Grad rec lady was blunt and very straightforward- nonetheless I still managed to get a lot of info from the trainees about their experiences which was great.
I don’t feel intimidated by 3000 people, you’re just as unique and have something to offer as all the other candidates
