Big 4 T&R/CorpFinance internship - helpful for IBD?


Basically I have an internship next summer with one of the Big 4 in Corporate Finance, T&R and am thinking about the next step. Obviously if things go well then maybe I’ll get an offer which would be great, but otherwise I need to plan ahead. How much weight would the internship have when applying to IB? I know that transactional work would set me up well for the IB division but would it carry enough weight to land some interviews given that I don’t go to a ‘target’ uni etc? Thanks!
