Lengthy process but worthwhile. 3 stage interview with role play. You are not expected to know everything about the services but be able to have a linear approach to problem solving. First stage will be on the phone with HR, second with managers, third will be with Director. Prepare properly and you will be fine. Ask lots of questions and be prepared to have lots thrown your way.

I received an email from the internal HR to arrange an interview over phone or Skype. After the interview, the recruiter told me she would have given me a feedback in two days, but, after three days I hadn't received a reply yet. I solicited the recruiter and after four days she emailed me saying that "Competition for this role was very strong and I am afraid other applicants demonstrated a closer match to our requirements".
