The process is advertised on the Babylon Android Playbook on their github page, and it is followed strictly. It was overall pretty fun, I had chats (rather than interrogations) with multiple roles: designers, product managers, engineers. There is a code test to do at home before being invited to on-site interviews, and it is a good test to estimate the level of the candidate..

Very clear steps regarding what was required and who I was meeting with. The interviewers were very mindful and friendly. Whenever there was something not clear, they were open to discuss about it.
