I want to work in Computing without a computing degree
This is not a problem: there are many one-year “conversion courses” designed to give graduates from any degree subject an intensive grounding in programming and other IT skills. A few of these are listed below. All kinds of first degree disciplines may be combined with these skills to give you an advantage in career areas such as finance, media, library/information work and law.
If you don't want to do a postgraduate course, there are a few employers who will train you on-the-job, although graduates in business, science, maths and engineering may be most in demand here. There are also opportunities within IT companies in non-technical roles such as sales, marketing and customer service.
Now you wear more computing power on your wrist than NASA had available for the whole Apollo project.
