looking for a job as an international student

Hello, I’m an international student in Brno from a non-EU country, and I’ve been struggling to find a job. I have around five years of experience in customer service, so I didn’t expect the process to be this difficult - especially for entry-level or low-skilled positions.

I’ve applied to places like McDonald’s and KFC and still got rejected. When I do manage to get interviews with larger companies (for example, Zebra), I often end up being ghosted for months, with no response to my follow-up emails.

What makes this even more frustrating is that I’ve had my CV reviewed by HR consultants, and they’ve confirmed that it looks solid. Despite that, it’s been almost six months, and I haven’t received a single job offer.

I’ve never been unemployed since I turned 18, so this situation is really affecting me. It’s starting to take a toll on my mental health, and I genuinely don’t understand what I might be doing wrong. Has anyone been in a similar situation or have any advice on what I could do differently?
