Sales Engineering seems like a pretty good gig. You get to come in and do proof of concepts. Make things look like they work. Tell the customer anything is possible and everyone loves you. Then I, the consultant, have to come in and break it to them that no, not everything is possible. Also as the sales person you get a commission but I actually have to deliver results to get us paid and I get no additional compensation for that. To top that off my take home pay is about 1/10 of what the customer pays for my time.
