In the office, there is a clearly defined and easily accessible organisation chart, so you can see the structure and members of each team. However, at least in the teams I have been in, the senior leaders sit with the rest of the team and are very approachable. Everyone is very friendly and willing to answer questions. I think the most repeated phrase I heard in my first week was "let me know if you have any questions," which everyone said at least once! The teams interact with each other a lot, as well as other teams in the business, and so are very friendly with each other, often eating lunch together and happily attending social events together. RAA has a social club that organizes events outside of work, but the data teams have also organised some of their own, such as go-kart racing, bowling, games afternoons, quiz nights, and pub crawls, as well as occasionally going to the pub for lunch on a Friday. The graduates are also quite a close group, as there are 6 grads in each year, and you attend a lot of workshops and experiences (sitting in call centres, driving out to different shop locations) together.
