It depends on one thing: whether you create your resume from scratch or use an existing document. In the latter case creating a new resume takes only a few minutes as you just have to update the content, choose the layout and you are ready. When you create something from scratch you still have to enter the content in the resume – unless the software provides pre-written phrases and/or sample resumes – but it is guaranteed that you will be ready with your document within 15 minutes.
