Should I ask if I haven't received the notice after one month of interview?

I feel good about myself in the interview, and I have a good chance of getting the job. But the key lies in the employer, which has a standard judgment on talents. They are looking for people who meet the job and can create useful value for the company. To meet this demand, they will inform you of their employment situation. You said you haven't received the offer for a month. You should ask the employer at this time, and you shouldn't wait any longer. And be prepared to continue looking for a job. Don't stick to it, take the initiative. Treat it with a normal heart.
