Actually don't agree, don't think the Belgian legal market compares to London (even if it is A&O Shearman, Linklaters and Freshfields).
Also how substantial where this internships in the first place? Seems unlikely to already have 3 big internships like that tbh.
The 3 of them were all 1 month programmes over the course of summer.
If you have good grades and are top of your class it is quite easily accessible in Belgium... (At least compared to London from what I see here 😅)
