Yes, much better to go in and get the job under false pretenses.. that surely will lead to longterm success.
Marketing is making your product shine in a good light, not selling a product you don’t have.. that’s called false advertising and is actually illegal in some countries. Not something I would really advise.
I remember saying "lying is bad".
The rest is a matter of nuances.
I wish you a Happy New Year, Justine!
