Initial phone screen by recruiter. ~30 min phone interview with a deployment strategist. Included general talk and an example business case. Three on-site interviews during one day in London. Did not proceed after this. They took much longer to return than they said they would and did not provide any feedback. Good interviews. Discussed my earlier experiences and my skills. One problem solving task during each interview: a math question, a business case and a programming problem. Good experience until the much delayed response time and lack of promised feedback.
