Do I need to have completed a SA role to qualify for BB IB? Further, am I too late to apply for 2019 SA if I still have to do so

Hey guys,

I am really wondering, do I need to have completed a BB IB SA role to qualify for BB IB post my Masters? Further, am I too late to apply for 2019 SA roles if I still have to do so?

Finally, as a student from a non-target school somewhere in Europe, do I actually stand a chance for IB roles in e.g. London? Or am I e.g. better off applying for off-cycle IB internships at local banks/boutiques and hope to roll into BB IB later on?

Thanks for any input guys, would really appreciate it.
