Two interviews. First interview was a case study. You were given two hours to analyse a potential acquisition. Purpose is to test your basic understanding of financial due diligence. Good idea to include cash flows, net debt, quality of earnings, some commercial due diligence. You are required to type up your findings in a report. After two hours, a director came in and you had to present your case to the him/her.
If you passed the case study, you had an hour interview with a partner. This was less skills and more interest. I was asked about some of the recent activity in the market, what I expected to do in the job, some of my favourite deals, etc.
