Hey guys need some tips on what to do next.

So I had my performance review for my 3 month internship and it was exclusively positive but my company lost a lot of clients (its a software house) and they fired 30 employees. Due to this my contract won't be extended..

They promised to give me a recommendation letter and some tips to work on my cv. They also promised to call me back if they got more projects but that would be until next year most probably.

So what's the standard routine for devs after kind getting "laid off", I'm a full time uni student but since my uni isn't that complex I can pass without studying.
I was thinking of perhaps working at a mcdonalds or helpdesk while applying to more jobs but it honestly sucks that I lost this massive opportunity that took me months to get.

(I live in Poland if that changes anything)
