Looking for a part-time retail job in Central London – any advice or referrals?

Hi everyone,
I’m a Computer Science student at Goldsmiths, University of London, and I’m currently looking for a part-time retail job in Central London or the City of London to fit around my studies.

I’m particularly interested in roles at Apple, Virgin Media O2, EE, Vodafone, John Lewis, or similar customer-facing retailers. I’ve applied online to quite a few positions but haven’t had much luck so far.

If anyone knows of stores that are hiring, has any advice, or is able to provide a referral, I’d be incredibly grateful. I’m happy to travel across London for the right opportunity.

Thanks in advance for any help!
