Can strongly recommend getting some kind of flight operations job at a local operator. Think about air taxi/private jet companies and the like. Not only will it be relevant experience (it's amazing how little some pilots know about what really goes on behind the scenes!) but it may also get her socialising and mixing with the right kind of people. I joined a local air taxi company when I was 18 and fresh out of school, and it taught me a lot especially concerning interpersonal skills.
In the meantime, perhaps contact CRM Aviation in White Waltham. The husband is an ex-airline pilot and runs/owns the school, but his wife does interview preparation courses. All of the feedback I heard from their students is very positive. Airline interviews are extremely rare to come by, and she may find herself unable to re-apply again for a certain amount of time (depends on the airlines internal rules) - don't let her waste another chance!
