No you should not. You should say:
If I were you, I wouldn’t listen to people who say bad things about me.
If I could interview Angelina, I would ask her where she currently lives.
You should think of the past tense, in a second conditional clause, as a non temporal tense, its purpose is to convey the hypotetical nature of the sentence.
Indeed many languages, such as my native language, italian, do have separated tenses for hypotetical use only and english used to possess it as well: "were" is actually a trace of a now gone conditional tense.
Consider this example:
If I had known you were going out with the same guys that had bullied you, I wouldn't have let you out.
If we had to conjugate a verb that is expressing an action that takes place in the same time of the hypothesis according to the tense that you are using in the hypothesis, we wouldn't be able to express the fact that the bullies had already bullied you at the time you went out with them.
