The application process consisted of 5 stages; I went from telephone interview to offer over the course of 4 weeks. The first was to send in a CV and Cover Letter (a nice change from the usual online application forms that larger companies tend to use which can be impersonal). I was then invited to a telephone interview with one of the talent acquisition team members. It was a fairly standard telephone interview - assessing my motivations for applying, what I knew about the job / industry, why I'd be suited etc. - but the interviewer also gave an opportunity for me to ask questions about the company too.
Following this, I was the invited for a face-to-face interview, firstly with the talent acquisition team (including my telephone interviewer) and then with two members of the Forensic and Dispute Services team. These essentially built on the telephone interview, but with some more in depth questions about the industry and my knowledge of it. The following stage is a Mathematics test (similar to the online psychometric ones that other employers use), a written English test and an Excel test. These are more to assess your level of skill in each area to work out where you might benefit from some training if you accept an offer.
The final stage was an interview with two more senior members of the Forensic and Dispute Services team, including the head of the graduate recruitment scheme. This interview was pretty tough. It wasn't tricky but there were some unexpected little case studies and a few unusual questions, so I came out of the interview without a personal sense of how I felt I had performed.
Probably the best thing about the interview process was having a dedicated member of the talent acquisition team overseeing my application for the whole 4 weeks. We communicated every week, either by email or telephone, for updates on my application status and my progress with other opportunities. You really build up a relationship with the team member who oversees your application. For most of the stages (including the final round interview) I heard back from them on the day or on the day after the interview. I think this very personal approach to the application process reflects the firm's internal culture well - everyone that I met was incredibly friendly. You are given lots of opportunities to ask questions and get a feel of what it is like to work at A&M. I much preferred this process to others that I was involved in.
