Work-search log: how detailed does it need to be? after 4 years as a nurse's aide

I am keeping a spreadsheet of applications, but I worry it is not what the agency expects. This is my first time dealing with any of this. I also did a résumé workshop at the library. Do interviews and workshops count?

Screenshots of the submitted application are handy backup when a posting disappears.

Thanks for writing this out. I went through something close to it 3 months ago, and it settled down once I kept a simple log of every call and form.
