This is a common first question in job interviews in English. An interviewer asks this to get general information from the job applicant.
If an interviewer says this to you in an interview, you should answer by telling them:
- your name (if they haven't already heard or read it)
- a short history of your most recent jobs
- why you want to work at this company
...and so on.
This is always a tough question to answer, even for native English speakers!
