finding jobs during the year?

i’m sure other people have posted about this but i didn’t find any answers that helped me. i’m trying to find a part time job for my 2nd year at LSE and it seems impossible.

i tried applying for 30-40 barista, retail, team member, etc roles and heard back from maybe 3-4 of them, all of whom did not hire me. campus jobs are barely available; there’s usually 8-9 advertised positions for the entire year, which a lot of people must be applying for.

does anyone have any tips on this? i’m an international student so i can’t work more than 20 hours, but i don’t mind any amount of hours atp lmfao.
