In the cover letter I tried not to make a reference to it but yes there's a line that says "in my current position I...".
So claiming ignorance with sending a CV that wasn't updated might not work. I was hoping to use that until I just checked the cover letter and found that line.
I made the mistake to try this out on ONE job application, literally one!
When were you made redundant and when was the job advertised (not when did you apply but when was the job advert first posted)? In the jobs I've appled for they have 2-3 month windows, if you were employed when the first job advert was placed then you can just say you wrote the application but forgot to send it for a couple of months.
Obviously if you applied straight away then you're out of luck...
