Sociolinguistics 5, Exercise 1: overt or covert?

Standard pronunciation in a job interview   overt prestige: standard and
                                            "formal" features expressing
                                            power and status

                                            features expressing solidarity and
                                            identity

The first example is my illustration of the overt-prestige definition; the
other two are the source's own.
