What should a software engineer CV focus on most?
Open
It should focus on the systems or products you have helped build, the technical contribution you made, and the outcome of that work. Tools matter, but they are more convincing when attached to shipped work, reliability improvements, or clear implementation ownership.
Should I include every programming language and framework I know?
Open
Usually no. Keep the tools that support your current target role and remove older or low-value items that add noise. A shorter, better-supported stack is often stronger than a long list with no context behind it.
How technical should the bullet points be?
Open
Technical enough to show credibility, but still readable on a quick first pass. Mention architecture, services, testing, or tooling where it explains your work, then add the outcome so a non-engineering recruiter can still follow the value.
Do side projects belong on a software engineer CV?
Open
They can, especially when they show depth in a relevant language, framework, or problem area that your recent commercial work does not. Keep them selective and make sure they add new evidence rather than duplicating your day job.
How do I tailor a general software engineer CV for different jobs?
Open
Keep one balanced baseline, then change the profile, highlighted skills, and first few experience bullets so the most relevant technologies, delivery context, and engineering problems appear earlier for each vacancy.
