Well yes obviously that is a very sound piece of advice!
I wish you the best of good luck but you may not get offered either job or, as someone else said, you may get offered the one you probably didn't want.
I think you will have the chance at the interviews, to find out a little more about the company, the conditions, the rosters, and then if you were fortunate enough to be offered both, you would find it easier to make a decision. Go along armed with relevant questions to ask, either during the presentation or during your 1 to 1 interview. Remember: you are interviewing them as well!!!!
Good luck and let us know how it goes.
