I quit my FT job two years ago when DS was a toddler and am now looking for something new.
Due to family circumstances, I'm looking for stuff that's local to where we live, mainly PT office jobs. However, I'm struggling a bit in how to 'pitch' myself in the applications.
At the risk of sounding like an arse, my previous roles were relatively senior, in a high pressure industry managing lots of people, high budgets etc to manage, with a salary to match (the last point is pertinent to new applications as some are asking for last salary)
I am trying to adapt my CV and experience to a new job - i.e. make it transferable skills - but I'm struggling especially when asked to explain why I want the job, as I don't think "I need a job for my sanity but need to be nearer to home for family reasons'' is appropriate 
I want to try and convey that at this point, PT office stuff is exactly what I'm looking for, and I can come in, do a good job, and no, I won't get bored etc. Any pointers on how to do this?
