First of all, welcome to WikiJob! I’m glad you’ve enjoyed using our forums - have you seen the main site too - Interview Questions for PwC, Deloitte, Goldman Sachs, Accenture and more - WikiJob
If you’ve not seen it already you’ll find some information on competency interviews here - Competency based interview - WikiJob which may be useful in your preparation.
At this level of interview you’ll be interviewed by a partner if one is free, but because partners have a pretty heavy schedule (and because clients take priority over graduate interviewees!) senior managers do also take interviews.
Senior managers and partners are top level people, with excellent knowledge or their business and their job. Whoever interviews you will almost certainly be highly intelligent, and informed about a wide amount of information, including current affairs, politics, economics and even art and culture.
The key point to remember is that whoever interviews you will not expect you to know everything. Don’t get flustered like some interviewees and try to impress your interviewer too much. They have been in their industry for a minimum of ten years and probably a lot longer. They may appear imposing and powerful, but they started exactly how you are right now! They want to see you are also informed and intelligent and understand the company and job you are applying for and know about relevant topics, but having some gaps in your knowledge is ok.
Although competency questions will form a large part of this interview (especially if you’ve been told to prepare competencies!) you should also expect more general questions. Your interviewer will want to find out exactly who you are (as well as what you can do) and if you will be a personality match for the company. Expect to talk about hobbies and interests as well as who you are as a person.

Lunch will be a chance to take a break and repose. Talk to the other graduates, but try to stay away from the ones who are nervous or excessive worriers, these guys will only drag you down! …talk to people who have been to other assessment days and interviews at other companies you are interested in and find out people’s view on other companies. Talk to HR to ask ay questions, and talk to graduate level staff - these guys usually get introduced to interviewees at some point. When you talk to anyone who actually works at E&Y, even during lunch, make sure you talk about the company with excitement and show your enthusiasm. This is an assessment day - you are continuously assessed - be on your best behaviour at all times!
Regarding the group assessment, we have some information available here - Group exercise - WikiJob - I’m afraid I can’t be more specific on this, but perhaps Chris or another member of the forum will be able to elaborate…
Good luck with your application. We certainly would appreciate reading about your experiences after your interviews and assessments! User contributions are the best way to make WikiJob into an even better resource!
Thanks again for your kind words - remember to spread the word about us at your assessment day!
