Frequently I will have an interview with a hiring manager that last only for 30 minutes. The person will say they want to discuss: my background, my work, my method of working, a discussion of the company and the role, and then they answer my questions if there's time. Then they begin by either giving a brief explanation of their background or a review of the company, or both.
Often, we seem to run out of time before getting to all the questions. 30 minutes might be too short of a time to get through it, but I didn't set it up.
Obviously, some good advice might be to keep it short and sweet, but I don't want the interviewing thinking I don't know what I'm talking about because I didn't give a more detailed explanation.
