Updating and Enhancing Your Resume for Software Engineering

When you’re moving into software engineering, your resume isn’t just a list of past jobs - it’s your first proof of potential. Recruiters and hiring managers want to see not only your work experience but also how your skills, projects, and problem-solving ability align with the job description.

Tailor your resume to software engineering roles

Generic resumes rarely work. A hiring manager can spot a copy-paste application in seconds. To stand out:

• Mirror the job description → If the role asks for “experience with Python and APIs,” make sure those exact keywords appear under your skills and project descriptions.

• Highlight measurable outcomes → Instead of “built a website,” write: “Developed a web application using React and Node.js that handled 1,000+ monthly users.”

• Show adaptability → As a career changer, position yourself as someone who can connect past expertise with engineering.

Highlight transferable skills

Many non-tech roles provide skills that are valuable in software engineering. The key is reframing them:

• “Managed complex spreadsheets” → “Automated workflows using Python scripts to reduce manual data entry by 40%.”

• “Led project teams” → “Collaborated with developers and designers to deliver software solutions under tight deadlines.”

• “Analysed business data” → “Applied SQL and Python for data analysis to generate insights that informed product improvements.”

Add proof of new skills

Employers want evidence you’re already building technical expertise. Include:

• Certifications (freeCodeCamp, AWS Certified Developer, Google Cloud, Coursera).

• Projects → Web apps, mobile apps, or automation tools that show you can ship real code.

• Portfolio or GitHub → Share links to your repositories and highlight your best work.

Use a modern, ATS-friendly format

Recruiters and applicant tracking systems (ATS) scan hundreds of applications. Make sure your resume is clean and easy to read:

• Clear sections: Professional Summary, Technical Skills, Projects, Experience, Education.

• Bullet points starting with action verbs and ending with measurable results.

• No design-heavy templates that confuse ATS scanners.

👉 Pro tip: Pair your resume with an updated LinkedIn profile and, if you want to stand out further, create a short video pitch with Reslink. This shows your communication style and enthusiasm - things a traditional resume can’t capture.

And if you’re not sure where to start, you can download free CV templates from TechTalk to build a strong foundation before tailoring it to each job search.

Networking: Building Connections and a Personal Brand

In tech, networking is just as important as coding skills. While you need the technical foundation, most jobs - especially for career changers - are landed through referrals, communities, and visibility rather than cold applications. In fact, studies show that up to 85% of jobs are filled through networking (HubSpot).

Why networking matters in a career change

Breaking into software engineering can feel intimidating if you don’t have years of experience. Networking changes that. It helps you:

• Get past ATS and land referrals straight to hiring managers.

• Learn what different companies expect from entry-level or career-switching engineers.

• Build confidence by surrounding yourself with peers and mentors who’ve made the same transition.

Effective networking strategies for engineers

• Join online communities → Platforms like freeCodeCamp Forum and Reddit’s r/cscareerquestions connect you with engineers and mentors who share advice, opportunities, and interview prep tips.

• Attend local meetups & hackathons → These events are fantastic for meeting engineers face-to-face, building your portfolio, and showcasing your problem-solving in real time.

• Leverage LinkedIn → Connect with software engineers, recruiters, and engineering managers. Send thoughtful messages — not just “Can you get me a job?” but “I’m exploring backend engineering and would love your perspective on the best projects to build.”

• Ask for informational interviews → A 15-minute call with an engineer at your dream company can give you insider insight into their interview process, tech stack, and work culture.

Building your personal brand

Networking gets you into the room. Your personal brand makes you memorable:

• Post about your projects → Share GitHub repos, blog about what you’re learning, or post quick problem-solving breakdowns.

• Document your learning journey → “I just built my first REST API in Node.js - here’s what I learned.” Posts like this show growth and persistence.

• Stay consistent → Make sure your CV, GitHub, and LinkedIn tell the same story. Hiring managers often check all three.

👉 The takeaway: Don’t wait until you’re job hunting to start networking. Building relationships in the engineering community early will give you access to opportunities you’ll never find on job boards.

The good news? Tech companies often value diverse experience if you can connect your past skills to the job description and show you’ve put in the work to build your technical foundation.

Common interview questions for career changers

You’ll likely face a mix of standard interview questions and ones that specifically probe your transition. Examples include:

• “Why are you making this career change into software engineering?”

• “What steps have you taken to build your technical skills?”

• “Tell me about a project you’ve built - what was the problem, how did you solve it, and what was the outcome?”

• “How does your past career prepare you for working as a software developer?”

How to demonstrate industry knowledge

You don’t need to know everything, but you should be able to show curiosity and up-to-date awareness. To prepare:

• Research the company’s tech stack (languages, frameworks, tools they use). Mention them in your answers.
  Reference trends like AI, cloud computing, or agile methodologies to show you understand the industry.

• Follow engineering blogs and podcasts (e.g., freeCodeCamp, The Pragmatic Engineer) to speak confidently about where the field is heading.

Framing your past experience

Instead of apologising for not having a CS degree, reframe your background as an asset:

• From teaching → “I know how to break down complex problems - a skill I now use when writing and documenting code.”
  From finance → “My analytical mindset helps me debug faster and optimise algorithms.”

• From marketing → “I’m used to testing, iterating, and using data to improve — the same approach I apply in software development.”

Practice with mock interviews

Nothing builds confidence like practice. Try:

• AI tools like Google Interview Warmup to simulate questions.

• ChatGPT prompts → Paste your CV and a job description, then ask it to act as the interviewer. Example:
  “You are an interviewer for a junior software engineer role. Based on this CV and job description, ask me 10 technical and behavioural questions. After each response, give feedback on how I can improve.”

• Communities like TechTalk → Join live mock interview workshops with peers and coaches to refine both your technical and behavioural answers.

👉 The takeaway: Interviews are your chance to connect the dots between your past career and your new skills. Show that you’re motivated, adaptable, and capable of contributing as an engineer from day one.
