I would mainly put it if it is somehow relevant for the job you are applying to. Or you could put it in a section about your interests.
yes it does matter what address you put on a job application, the address you put on a job application is supposed to be where you reside, no where else.
go to the job and ask for an application
For example your aplpying for a Saturday job in a dog kennels, you would write.I love working with animals and i think the job would most suit me because i am a reliable person to depend on."Microsoft Excel is a popular spreadsheet application"."I need to complete a job application in order to be considered for a job interview""After the application of the medicine the patient started to recover".
I suppose you can, but you will not get the job.
yes]
yes you do
Be good
Yes.
No you dont
I wouldn't put the reason on the job application. You can save this for the interview and only if asked for the reason why.
Put not negotiable.
You need to put on the application that you left job to be at home with your children. No employer would down upon this.
