Actually, I didn't say employers won't be sympathetic to your past. What I said is that
they are likely to think that accomplishments are irrelevant if they aren't from a very similar job title and industry as theirs.
That said, I think most employers WOULD be sympathetic to what you did, depending on how you explain it. I don't know enough about you to advise you any further about how to explain it so it's seen in the most favorable light to you, nor do I know enough to advise you if you would be better off
waiting until an interview before you bring it up.
And, remember, EXPERIENCE is where you find it. It's the BENEFITS, ADVANTAGES, AND CAPABILITIES you have gained as the RESULT of your experience that, if marketed effectively, can help you get your foot in the door.
