Greenhill & Co. interview questions

You apply through recruiter, followed by a test, followed by a first round interview, followed by a superday (4 interviews and a case study) and then you get the offer

Pretty difficult, drill in on all IB concepts. the only 2 behaviorals were why IB and why greenhill, otherwise first round is purely technical. prepare well all the IB concepts, especially valuation and ebitda margin, also some merger math and advanced accounting.
