When you arrive at your company, should you call the person who informed you first, or go directly to the personnel department to learn about the new person's first interview?

If the person who informed you tells you the specific location, time, department and other information of the interview, you don't have to call again, just follow the instructions and go to the interview.

If you are not told the specific information, be sure to call the person who told you, ask about the specific interview time, place and department, find the gentleman or lady, or directly find the person who told you. When you receive the notice for the first time, you'd better ask the prepared questions clearly first, which also shows that you attach importance to the interview and can better reflect the characteristics of doing things well.
