I found a company at seven or eight in the evening and wanted to know about their recruitment. Is it appropriate to call so late?

Call them at seven or eight in the morning. They should be busy now. They must make plans for this day. There is no one at noon. Many companies have meetings at four or five in the afternoon. So 9 am to 10 am and 2 pm to 3 pm are more suitable. It doesn't matter much if you contact the person in charge of recruitment. He is in charge of this work and has access to specific information at any time. At seven or eight o'clock in the evening, the general companies are off work. . . The personnel department has less overtime.
