Applied in December 2017, had a phone interview and face-to-face interview at their office in London shortly after. They will question you on your CV, cover letter and experience. Questions are mostly the same so if you get through the first stage you will know what to expect. Make sure you know all your subjects well as they could ask you to expand on what you're talking about. There is also a timed maths test before the face-to-face interview that shouldn't be too difficult for maths/econ grads.

Initial Phone Screen (stock pitch, where the FTSE index traded atm, what does the P/E ratio show, why Berenberg) Face to Face Interview (what are the three main valuation methods, what does the P/E ratio show, walk me through a DCF, CV based questions, motivational questions) Assessment Centre (Behavioural, more advanced technical, stock pitch presentation, group task)
