It's less about steps, but having the skills and passion to be successful in the industry. When I'm hiring Computer Science majors, to become Presales Solutions Architects here are the skills I look for:
1. Proven technology skills, outstanding interpersonal abilities, strong written and verbal communication skills.
2. Attention to detail and problem-solving capabilities.
3. Being an innovative thinker and a self-starter with a desire-to-win type mindset.
With those skills, your employer should be able to teach you the rest!
Chrissy recommends the following next steps:
I don't think there are clear-cut steps to take, but I'd recommend developing a personal project! Find a language that you enjoy, think of a project that excites you, and go for it. You'll sharpen your programming skills, have a project to show off at the end (and possibly add to your resume down the road), and have fun working on something you're passionate about.
Plus, depending on project, you might pick up some knowledge on algorithms, data structures, etc. which will give you a head start as you head off to college and further explore those areas of computer science.
