Frequently asked questions

Should I include personal projects on my Software Engineer resume?

Yes, especially if you are early career or changing tech stacks, since personal or open-source projects demonstrate initiative and real coding ability. Link to a GitHub repo or live demo so employers can verify the work directly.

How technical should my resume summary be?

Keep it concise and specific, naming your core stack and the type of systems you build rather than generic phrases like 'passionate developer.' A recruiter should immediately know your specialization and seniority level.

Do I need a cover letter for a Software Engineer role?

Many companies do not require one, but a short, targeted cover letter can help when you are pivoting industries or explaining a gap. If the job posting does not ask for one, prioritize a strong resume and portfolio instead.

How do I list programming languages if I know many but am expert in few?

Group them by proficiency, such as 'Proficient: Python, SQL' and 'Familiar: Go, Rust,' so interviewers calibrate expectations accurately. Avoid listing a language you cannot discuss in technical depth during an interview.
