After the interview, I said I was waiting for an appointment for a second interview. Why haven't you called?

If you like this job very much, call again to express your wishes and ask how soon you can get a reply. Just say that several others are also interested in you, but you are still partial to this company and feel the tone of the other party. If I really want to hire you, I will definitely reply soon. If not, there is basically no hope. You should find another opportunity, don't seize it. Now is the recruitment peak, don't lose it easily.
