In Australia, it's generally accepted that resumes should be around two pages in length, and this is considered normal across many industries. However, when it comes to management consulting, the one-page rule is often followed, as consultants typically need to be concise and to the point in their communications.
If you're applying for a management consulting position, it's a good idea to adhere to the one-page rule and focus on presenting your most relevant and impactful experiences and achievements. Use any online resume maker to manage your resumes one for each job. You can also consider using a visually appealing best resume format to help your resume stand out.
Ultimately, the length of your resume should depend on your specific circumstances and the requirements of the job you're applying for. If you're unsure, it's always a good idea to consult with a career advisor or recruiter who can provide more personalized guidance.
