I'm less grumpy than usual today so...1. Google. 2. Call or email the office in question, tell them you are interviewing there, and ask for some more specific information for your interview prep (or call London and ask them for the info if you don't feel happy with the regional office knowing you are asking)3. Contact someone in the regional office in question, in your service line, via LinkedIn and ask them. Good opportunity to strike up a conversation to get an insight into culture etc too, possible networking opportunity and may even help your chances if they like you/you impress them.4. Last resort. Come on here and ask without doing any of the above.
