First interview lasted about an hour. It was made up of random questions, some of which are similar to what you’d expect (i.e. what motivates you, are you good in a team, can you lead as well as follow etc etc), basically what you read about in the competency based section on wikijob. However, there were some stranger questions, such as should there be more hours in the day and what gets you up in the morning, are you better at theory or applying theory in practice (I said the latter, theory seems irrelevant to me if it can’t achieve something tangible at the end of it). I was told that each question has a ‘yes’ or ‘no’ answer (not necessarily a correct answer, but your definitive opinion) and then you have justify yourself using an example or your general life experiences.
I found it difficult to prepare, there was none of the usual 'why EY, why your department, tell me a time when you jumped over a mountain etc etc! It was mainly your opinion and ability to put together a logical argument and have an interesting conversation with somebody from EY (my interviewer was a senior manager, NOT a partner at this stage). Environment was relaxed, felt almost informal at times. I actually really enjoyed it, felt a lot more engaging than the usual treadmill of repeating questions.
I hope this helps, if you need to know anything else I can try to help, has the interview about 3months ago so little vague so I’m sorry about that!
Just be engaging and show you can get along with a senior EY employee and form some unique/original ideas that have some justification and logical reasoning behind them and I think you’ll be fine.
Hope it goes well, good luck!
