Indeed. The perfect Pre-sales example would be Conanius above (who has a great job by the sound of it, being the link between the business and IT is a valuable role).
And actually, if you have half a personality and the ability to talk to people AND LISTEN... isn't that difficult.
If you want my honest opinion... Consider the long term plan. I used to work in sales, but it was home electricals. I earned more with commision (by about £6k a year) than my first IT Job. You might need to take a step down.
I started out on an IT Service Desk, answering calls, resetting passwords, changing printer cartridges, cleaning mice for directors, literally the lowest of the low job spec wise.
I kept my head down, worked hard, had a good first line fix rate, didn't mess around between calls, and after 6 months in the job started to get project work improving our services (specing requirements for online forms to request new software and all that sort of jazz).
It got me out into the IT business, and importantly, got my face known. I got a few lucky breaks, got on some really useful training courses, and it just sort of went from there.
I'd strongly recommend an IT Service Desk as a great first IT job. You learn a lot about the good and bad support areas if you want to get technical, and if you are good at your job, some of these will let you have permissions to do their work for them if you prove yourself, further increasing your skills (maybe something basic like a file restore, but its a start). It's all about doing hard graft and getting opportunities.
I'm speaking here like I've made it or something, far from it. I'm 9 years in to my career in IT and I'm not too proud to say its stalled at the moment. I've sort of plateau'd a bit, and I think in part thats because I need to move to a different organisation.
So you get an idea of what I've done:
IT Service Desk Analyst
Problem Manager (3 Months to help improve processes)
IT Service Desk Management Team
*swapped departments*
IT Service Desk Team Leader
Service Delivery Manager (by far my favourite job, amazing amounts of authority to just get the job done)
Technical Operations Manager
and now.. IT Service Manager
They all sound like 'nothingness' jobs really, and to be honest, the last 3 were basically doing the same thing. Managing a team of other people to get a job done and ensure IT does what they need it to do for them.
So... if all that was TLDR, consider starting off on an IT Service Desk. Its a great way to know how a company works, and its a fantastic foot in the door. If I had my way EVERYONE who joined IT would have to do at least 1 month on their new companies IT Service Desk so they can get that overview of IT Health, Customer Demands and generally a good old look at what the IT world looks like.
