Going to other cities for an interview and staying in a hotel is too expensive. Is there any good way to spend the night temporarily?

If you are a girl, I suggest you go to a hotel. It's not safe to make do outside. It's best to go to a chain store, because it's better for girls to pay attention.

If it's a man, make do with going to more places. I think I came to Beijing alone and left my footprints on the chairs in the park, on the stations, in the small tents and in the Internet cafes. This is the result of my strong graduation, and it is also a kind of survival.

Let me concentrate on building a tent.

Tent. Every time I get off work, I start to go to the suburbs dozens of kilometers away by car, find my hidden tent, start to set up a tent, set up a tent to eat cakes or instant noodles bought on the way, and start to sleep tonight. I lived in a tent for over 1 month. At that time, it was summer and autumn communication time, and it was great to have more mosquitoes.

Actually, your question is very simple. In order to save money, the best way is to use local materials as long as it doesn't cost money, so there are many ways.
