OpenResume is a free, open-source, and powerful resume builder that allows anyone to create a modern professional resume in 3 simple steps. For those who have an existing resume, OpenResume also provides a resume parser to help test and confirm its ATS readability.
There are two ways to create a resume today. One option is to use a resume template, such as an office/google doc, and customize it according to your needs. The other option is to use a resume builder, an online tool that allows you to input your information and automatically generates a resume for you.
Using a resume template requires manual formatting work, like copying and pasting text sections and adjusting spacing, which can be time-consuming and error-prone.
Me just using LaTeX[1] with hundreds of templates[2] with no formatting problems for 18 years now...
I just... make a resume. No template, I just use a word processor to lay out what I want where I want. My basic format is:
quick details on the left - name, contact info, links to portfolio, etc
experience on the right - 3-4 items, newest on top, with 3-5 bullet points per item
skills and certifications on the bottom
I spend 10-15 min making it look a little pretty, then spend about 5 min customizing it for whatever role I'm applying for. If I really want the job, I'll put some effort into a better cover letter and do some research about the company, bringing total time investment to 15 min or so. I can knock out 5-10 customized applications per hour, depending on how onerous their application process is and how many truly interesting roles I find. I keep track of every application in a spreadsheet, and follow up on the ones I care most about once/week.
