How about IKEA, Home Depot, or Starbucks? I even think working at McDonald's might be worth it since you can work your way up and become a manager eventually.

I applied to Costco but never heard from them.

I think applying to these places is difficult due to the huge number of people applying.

But, if you know someone else working at these places, such as Costco; it might help as a referral.

I wish you the best in finding a job now. I heard many places are seeking workers. It might be a good time to apply!
