They're wanting to hear you speak, to see how well you communicate.
Usually there is less concern about what you say and more of an interest in how well you are able to explain something that you understand.
Tell them about your experience, where you went to school, what you studied in college, talk about your hobby, how you believe that you can help the company. But be careful on that last one, you don't want to be perceived as someone who is trying to draw the conversation away from their topic.

Just introduce yourself the same way you would do a regular interview: state your name and talk about how you could be a future asset to a company.
Answering "How do you talk about your experiences in your previous company at a job interview?"
When this is in a job interview, answer honestly. But try to put a positive spin on your answers. Don't talk badly about yourself.
There are many ways to introduce yourself in a job interview. You could start by saying your name and reason for applying.
Talk about why you want the job.
Tell something about yourself.
The main thing in an interview is to come across as confident and friendly. So you can anticipate as part of any interview you will be asked to talk about you, your prior experience, how you fit the job. On the basis you can anticipate this you can also prepare for this type of question. Make sure you practice your answers so that at the interview you can focu on presenting yourself well rather than worrying about what to say.

bold and polite
There is not a difference between describing yourself and telling about yourself in a job interview. This is a time when you want to try and sell yourself so the employer will want to hire you.
just be yourself
