It is my first ask in this forum. I am not sure about proper grammar usage, so I want to ask someone who knows it well.
If I want to ask a person for a duration of time he has worked at the specific job and I am not sure if he still works or not, which tense should I use, Past Simple or Present Perfect Continuous?
A. How long did you work in that company?
B. How long have you been working in that company?
As I understand in option "A" I suppose that he doesn't work anymore, and in option "B" he keeps on working.
