I applied online, passed the Watson Glaser test, passed the first HR interview, and was invited to the Assessment Day. The whole process took 2 months in total. The assessment day was a long day, consisting of a presentation, Partner interview, written test, commercial awareness interview, office tour and lunch. The presentation requires a week-long preparation prior to the assessment day. The Partner will ask many questions on your presentation, followed directly by a Partner interview on competencies and interests. Spend time on understanding how the topic chosen in the presentation affects the firm. The written exercise (1 hour 30 minutes) requires you to write a report based on the substantial amount of information provided. Your report then forms the basis for the next interview with a Partner where you will be asked on your rationale behind the advice you gave in the written exercise and a general discussion on the information.
