Designer from Hong Kong

Hi everyone! I recently moved to the UK from Hong Kong and I’m looking for a graphic design job.

Do I need to write a cover letter? If so, how long should it be?
I’ve heard that UK graphic designers use fewer words and more images in their portfolios. Is that true?

I’ve been working as a freelancer in Hong Kong for the past 3 years and I don’t have a year of full-time designer experience. Do you think it’ll be hard for me to find a full-time designer job here?

Also, do most people use Indeed, Reed, and Monster to find designer jobs in the UK?

Feel free to ask me any questions about the design industry in Hong Kong too. :sunglasses:
