Advice for a freelancer returning to the workforce

@twpmarkeing - thank you for those comments. Much appreciated. Love your phrase 'freedom to starve at will'!
I am actually worried about personality clashes and that sort of thing. Very used to plodding away by myself in my lovely office, with nothing but the radio or just silence around me. The new role is going to seem chaotic and loud I think.

@iridion2015 - No, SCRUM is not used, but I will have a read about it and thanks for the suggestion.
