Kroll Valuation Analyst interview questions

Applied online with my CV and a few weeks later was contacted by a member of HR wanting to book a telephone interview. Fairly straightforward telephone interview. Was then invited to Assessment Day with 7 other people which involved a numerical test, a case-study exercise in teams of 2 or 3 which was then presented to two employees from the Valuations team, lunch with existing employees and 3 interviews after lunch. Assessment Day was rather strange in terms of the difficulty of the numerical tests without a calculator in addition to not being told to bring a calculator which was needed for the case-study when calculating a DCF. If you did not have a calculator like my group you were expected to perform a DCF on a mobile phone calculator which is quite ridiculous.
