I attended an in-person interview in London, as well as an online interview prior. Very friendly and straightforward - questions to be expected and interviewers were both smiley and encouraging.

The interviews were very casual, and all of the interviewers were nice and made me feel comfortable and engage. The only negative was that the process took a very long time. It consisted of an application process, multiple interviews over a couple of months (both behavioral and technical), phone screening.
