First up, congratulations.
I'm not going to respond to each of your questions but rather answer generally. First though, could you confirm exactly what the letter says? To say that you're being interviewed by "a managing partner" doesn't really make sense.
I would expect your interview to cover the following areas:
- your education experiences to date (why LLM, areas of particular interest so far etc, what have you found difficult etc).
- your extra-curricular activities (what do you do, what skills have you developed, what levels of expertise/responsibility have you gained etc. Expect a degree of grilling on these as the interviewer seeks to find out if you really have done the activity to the degree you have said)
- "why law". The interviewers are likely to drill down to find out (a) why law is of interest to you generally and (b) what it is about commercial law that interests you.
- "why A&O". This is hugely important. Expect to be grilled about why you want to join A&O. Bland, non-specific answers will be not be good enough here. You need to have concise focussed answers prepared which will enable you to show how you can differentiate between MC and non-MC firms and then between A&O and, say, Freshfields.
- "Why you". You wn't necessarily get this question but you should prepare for something along the lines of "So, why should we give you a training contract?". Its nasty but if you're ready you can nail it.
- "commercial awareness". I'd anticipate some questions designed to find out whether you know what's going on in the big bad world outside Uni. That could be a broad "What business-related stories have been of interest to you" type question to a more specific question about a particular story which has been running in the press. Clearly the latter is far harder to prepare for. Look at their website for articles/client briefings they've prepared: they're a great indication of what they regard as the hot legal topics of the day.
Don't ask us about the recruitment process at A&O: ask them! Call grad recruitment and ask them to confirm the next steps etc. I would also ask them if they can tell you the name of the person(s) interviewing you - that will give you something else to research.
You will inevitably have an opportunity to ask questions at the end of the interview. This is a further opportunity for you to impress - don't ask Qs which might indicate that you're not necessarily interested in working for a corp law firm (eg do you do lots of pro bono work, do I get a chance to work overseas). Rather, think of Qs which might demonstrate your own ambition or that you're thinking long term (eg where does the firm see itself in 5 years time?).
General advice? You will be nervous. They understand that. There will come times in the interview where they will deliberately put you under pressure to see how you react. Anticipate that and relax (if possible!). Don't be afraid to take some time to think of your answer. Pausing for 15 seconds might seem like a lifetime to you but to an interviewer it gives the impression of someone who is calm and in control. Pause, think carefully and then give your answer. Likewise, at the end of the interview don't be afraid to return to a previous question and revisit it - "Earlier I said X, Y and Z: I'd like to add something to that answer...".
What else - know your CV/application form inside out. Nothing looks worse than a candidate who doesn't know what they've written: it casts doubt on their credibility. Following on from the "Why A&O" question, it is essential that you research them as much as possible. Put together a folder with press cuttings etc which show what they've been up to (internally and externally) over the last 12 months.
