One difference that comes to mind is that while in advertising / marketing you'd need to get what your clients offer, what they'd like to be offering, and how to work with them, in tech you'd also need to understand how it is currently done. The fact is, it's often a mess, with lost, fragmented and conflicting knowledge.
And while both need to deal with unclear goals, figuring out what it is the client and truly needs, in one case you're selling what they have, or what they are, in the other you have to make something they want and will be able to use, support and sell.
That's very often a tremendous amount of uncertainty to work through.
