Across all three teams I've been a part of, everyone has been easy to get along with, friendly, and kind. There has not been much interaction outside of work hours. The tasks I work on tend to be quite individual, though I have no problem asking for help or advice when necessary and colleagues are always happy to make time and help out. Amongst others in the graduate program, there has been plenty of socialising with outside of work hours catchups, after work drinks, an occasional weekend picnic, coffee catchups etc.
