what is the proper way to answer to this interview question - How long would you be part of our company before you resign?

my advice is. Do not lie, but do not tell all the truth. I mean in interview sometimes they want to know how long are you going stay with them, because they don't want to train someone who is leaving soon it means to them they losing money and time also information.

also they always ask what can you do for us? or what is the advantage of hiring you? be careful answer as you are not the only provider. it's like exactly, they hiring you because they need an employee, same thing as well you looking for a job because you need the money and live your life... whatever your reasons. but think about everything before you say and take your time

I never heard that one before. I would say, "As long as it is profitable, I would work until I am too old to handle it." lol Good Luck!

i intend to make a career with this company
