Hello
Congrats on securing the interview, sounds like you are in with a good chance of getting the job. Just remember you are half way there if they are interviewing you, on paper you can get the job in their eyes - or why would they be interviewing you.
I haven't been in your situ, but I have interviewed lots of people in my time so I would say something like:
- "I took a career break to be at home with my family, which is now complete (even if it isn't!), so I am looking to carry on my career following my last role. Which is why I was so excited to see this role advertised, as I have the skills and experience your are looking for.
During my career break I kept my skills up-to-date with volunteering roles in the PTA* which required organisation, social skills, ICT skills and budgeting etc."
*Most parents could probably claim this, even if your help wasn't an offical role?
I wouldn't focus too much on what you have done in the past 6 years, if you can make some of SAHM experience tie to the corp world do, but if not just focus on what you did back them and how are you are ready to get back to it. etc.
Have you kept abreast of your industry? Can you demonstrate this by mentioning something current?
As somebody interviewing you I would want to know:
a) What you did before the break
b) why there was a break (assuming they don't know exactly why) and that it sounds plausible
c) how you will fit into a job/role nowadays (so a bit of the tying your gap skills to the corp role, how you talk about your previous role and how you come across).
I might be inclined to write some thoughts down about your last job to help you recall in the meeting. It is the thing I think they'll focus on, so if you can remember with clarity what you did, how you did it etc.
Not sure if that helps. A bit of a mixed bag of advice.
Best of luck. Try not to be too nervous. You'll be great.
