I’m currently 7 months into my career as a software developer. Before my current job I worked in marketing for 4 or so years. I have a degree in English Literature, and I don’t have a specific computer science qualification nor a bootcamp under my belt.
In the context of the wider industry – where job specifications often ask for a computer science (or at least STEM) qualification – I’m not a totally ‘typical’ engineer, but from personal experience I’ve encountered lots of people in a similar position to me.
How did I get my current job?
My biggest stroke of luck was already working at The Guardian. The engineering team here is very special - there’s a shared ethos which really values learning and sharing our understanding with each other, and we have a yearly Fellowship which aims to help people into their first software engineering gig. We also have occasional Associate Software Developer roles which ask for a similar type of candidate - this was the role I ended up landing.
When I first became interested in programming, I sought the advice of engineers here at The Guardian, doing my best to follow it. One engineer in particular spent many hours pairing with me, which gave me invaluable insights into professional code, IDEs, testing, React, best practices and much more - she was also a great inspiration to me as she had worked in publishing for years before making her career change, which made me feel like my ambitions were genuinely achievable with some hard work. Without her and others who helped me along, I can confidently say I wouldn’t have the job I do now.
There are really two sets of skills that you’ll want to improve before you go for your dream job:
- The craft of programming itself
- The associated skills and concepts that professional programmers grow through their day-to-day work
Bootcamps will try to teach their students both of these things, but bootcamps are expensive and time-consuming, and many of us can’t afford to take time out of work to attend a bootcamp, nor money out of our paychecks to pay for one. One of the biggest barriers for the self-taught programmer is figuring out what is really useful to learn - especially since programming and computer science are essentially fractal in their complexity, and have far more depth than any one person can master. On the plus side, there is a colossal amount of free knowledge available online.
Knowing what is most useful to learn is really tough - I will do my best to outline what I’ve found particularly useful further down this post.
I do have a few pieces of general advice that on reflection I think are especially important.
Lean on your connections, or make new ones
An especially useful thing I would recommend doing is talking to people who work in programming already, especially those who came from outside of the traditional STEM gamut. The advice given to me by those people was totally invaluable. I have found that people are often really open to sharing their experiences and advice to those who are genuinely interested in what they do. I talked to people where I work, to former colleagues, and people I’d known from school. They recommended things worth learning, books worth reading, and useful advice for interviews.
I’ve found that pairing (i.e. simultaneously coding with others) is an incredibly useful learning experience. Usually this will involve one person driving (physically typing on a keyboard), while the other makes suggestions and observations. If you can find opportunities to do this regularly, it can really help your development.
Write code whenever you can
My long commute into work was very helpful for my personal development. I spent 3 hours a day commuting to and from work, with an additional hour at lunch. That totalled 4 hours of dead time every day, time that could be used to move me towards my goal.
The best way to learn coding is to do coding. If you practise regularly alongside reading books, blog posts and documentation, and think independently about how you can use code to solve problems: your quality of learning will be much improved.
I would also advise learning one language deeply rather than lots of languages at a shallow level, as you will find that most modern languages have a lot in common at a fundamental level.
Create a personal passion project
A piece of advice I feel very strongly about is to work on a personal project yourself. Build it from the ground up, make choices about the programming languages and libraries you use. Solve problems, encounter bugs, improve things, and note what you’d like to do better. Ideally, start with a problem that you’d like to solve, or an opportunity that you think is waiting to be solved.
It doesn’t have to be a totally original idea - maybe you want to work on something like a digital calculator, or process the output of an API in an interesting way. Use version control like Github and make it open source. Perhaps think about a build/deploy process, or testing.
I’d recommend using technologies that you want to learn about: that way it will also be a great and purposeful learning experience.
Why? Beyond learning, many interview questions are related this: tell us about something good (and relevant) you have achieved. Tell us how you fixed a problem, how you made a decision. Tell us about a project you’ve worked on, and how you’d like to make it better.
You’ll know your own projects inside out and be able to answer questions like these with confidence, while boosting your own understanding of the technologies that companies would like you to have.
I made a chrome extension using NASA’s Astronomy Photos of the Day API - and I ended up talking about it in my interviews.
Find good resources
I paid for almost none of the resources I used, other than a couple of second-hand books.
Harvard’s CS50x - Introduction to Computer Science is also available online for free and gives an incredible overview of core computer science concepts - I highly recommend it, though it will take up a chunk of your spare time.
Codecademy is a fun and gamified representation of coding and doesn’t seem to burn you out as quickly as a scholarly book, but I think it can hand-hold a bit too much to get you thinking as independently as you will need to. Nonetheless, it offers a friendly introduction to programming concepts.
As I have written above, programming is a very deep and wide set of knowledge, and early on I struggled to know which topics were worth prioritising. I’ve tried to compile a long and detailed list of concepts that I have found personally useful. There are useful fundamental skills that you’ll definitely want to know, and beyond that - things that are worth understanding in order to stand out from the crowd but which are probably beyond the scope of entry-level software developer skills (I’ve highlighted these in green).
Really, this list is much more than an entry level role should expect you to know - but I think all of it is worthwhile knowledge. I’m far from mastering a lot of these items myself, but how I differ from myself two year ago is that I’m aware these things are worth knowing, and know that being able to talk about them will come across well in an interview.
It’s worth noting that this list is quite specific to a full stack web developer role.

Entry level schemes open to people outside of a traditional computer science background are something of a rare beast - I’ve only applied at The Guardian but I asked around my colleagues and found a couple of similar opportunities.
- The Guardian Digital Fellowship generally takes place every year. It offers a fantastic learning experience with fellows rotating around different teams in the department. We also have occasional ‘Associate Software Developer’ roles that are open to people with similar experience.
- The Made Tech Academy offers a 12 week coding course leading into a paid role, open to those with a little coding experience.
- The Sky Software Engineering Academy is open to those with any degree plus applied knowledge of programming.
- ITV have an academy, though it’s aimed specifically at technology graduates.
Plenty of brilliant software engineers come from outside of the traditional Computer Science background. Ultimately a company will want you for the value you bring: your work ethic, expertise and personality - and for an entry level role, the right company will overlook specific qualifications if you’ve gone the distance of learning under your own steam. Don’t let self-doubt stop you from pursuing a career that feels like the right fit for you.
