Just saw on the main work experience page under my account it says:
“You will need to enter an end date for all positions including your current work experience. You will be able to update the end date as needed.”
I guess that makes sense, but you’d think they’d have made it possible to say “current”.
I can’t remember what I did for my application, but I didn’t remember this being an issue. I think the ‘end date’ is meant so that you total 4 years experience, so it doesn’t matter whether your ‘end date’ for your current job is actually a real ‘end date’, it’s just a date so that the sum of all your work experiences is more than 4 years.
