Is it worth doing a traineeship in EIB?

I was wondering if it’s worth to do a traineeship/internship for 5months in EIB (European Investment Bank)? I’m about to finish my MSc in investment & finance at QMUL by the end of August and I didn’t have any internship in IB before so thinking if I should accept offer from EIB or I should look for an internship in some boutique IB or small PE if I want to move to investment banking??? Obviously now it’s a bit too late to apply for Top IB internships...
