Thank you jfim and paxys. We are starting with interview practice but will extend it to other professionals. Paxys when you said "pro" means something different, can you elaborate it a bit?
thanks for the reply, paxys. According to your link, the negative meaning is shown as the third use case, it seems the primary use of the "pro" is to mean "professional".
As with everything it depends on the context and how you use it.
And this definitely made me think of prostitute first.
