I got a graduate position earlier this year in an ad-tech company, coming from 10 years in a completely unrelated industry and without a degree (I'm 33 and in the UK).
I worked through some Codecademy courses, developed my own site and blog and got to grips with things like Ad-Sense to get a feel for the ad-tech side of things. I pushed my self-taught achievements and motivation in my CV as well as my 10 years prior in a stable corporate environment.
I had to take a pay cut to get my foot in the door, but within 6 months I was picked for another team and was back up to my old salary. I'm now in tech support, but not IT specific (it's more APIs, datafeeds, SQL and site debugging). I get plenty of exposure to the underlying company tech and there are a lot of avenues for advancement in the future so I'm really happy I made the career jump.
