I wouldn’t worry too much about the early employment details here. I think the important piece for them is that you did not claim social welfare benefits before you left the U.K.
I was vague about my early years of employment after returning to Ireland as I can’t even remember some of it. I know I didn’t find a job for at least four months after my return, maybe even six months. I just said various employments, or something like that on my form. I’ve had my letter and was awarded 17 years at Class 2, which includes years 2023-2024 so I know they didn’t dig too deeply or ask for clarification. I think it’s important that you’re working now as well.
