Clearwater International interview questions

The interview consisted of around 16 students for about 4 roles (1 per office). It was hosted at hotel in Birmingham and the day consisted of a group exercise, case study (prospective acquisition for a PE firm). Discus pros, cons etc - looking for how you think about this scenario. Lastly there was an interview. Annoyingly they took 2 weeks to get back to me with a result and when they did I had to wait a week longer for feedback which was brief. They should manage graduates expectations better
