There are a few basic rules when putting together a resume. I highly recommend Googling other articles/posts/etc about how to put together a great resume so you have a few perspectives on best practices. Take all things I say with a grain of salt.
Let's get started~!
Similarly to cover letters, I recommend keeping things pretty traditional for the sake of predictability for the reader. According to a variety of surveys and sources, a hiring manager or recruiter only spends an average of 6-10 seconds looking at your resume. That means it's REALLY important to be efficient, clear, and concise with the most important information that you need to include! The reader needs to immediately find what they're looking for.
The other reason that I recommend keeping things predictable is that you want to avoid leaving things open to interpretation. Funky graphics or confusing descriptions can be interpreted in SO many different ways, and you never know how the viewer is going to take them. You can read the room. Your resume can't. So get the core message across, keep things clean and straightforward.
In case you haven't read my Cover Letter 101 post, here's an important relevant paragraph:
When you are applying against hundreds or thousands of other artists, you want as many factors in your favor as possible. Even the tiny ones. They add up! When you write a funny or "artsy" cover letter, you're leaving a lot of up to interpretation. Sure, the reader might love it and there's a slim chance it'll work in your favor. But a lot of folks will toss that funny cover letter away because they really just want to know why you're qualified for the job and that's it.
On top of this, remember: your resume and your cover letter are not the place to stand out, especially when applying to junior jobs...
The way to stand out is to have badass art. No time spent on your skills is wasted. Stay focused on improving and making awesome work in order to really grab their attention.
What you absolutely MUST include:
What you *might* want to include:
What you do NOT want to include:
Do's:
Don'ts:
I have no professional experience... what can I do to fill out my resume if I've never worked in a studio?
This is THE question. But- I have potential answers!
Anything that demonstrates you are collaborative, proactive, engaged in your community and/or industry, growth-focused, and/or resourceful can be a great point on your resume. When getting into games, my "community involvement" section was bigger than my "experience" section.
Here are some things you can do to boost a slim resume:
You can include day jobs to round it out, but I recommend using no more than one or two on your resume. Try to keep things as relevant as possible.
Should I include social media on my resume?
I do not ever recommend putting any social media on your resume of which you would not want to explain the posts to your interviewer. Assume they will always check whatever is on your resume, as well as anything else they can find. I know of situations in which the interviewer literally had printed out some of the candidate's tweets to ask them what they meant. Always be aware of the impression you send out to the world, especially alongside your professional work and in public channels.
Social media sends a first impression about what is important to you and how you communicate with others in a public place. It CAN help- we work in a very social culture-focused industry- but make sure that it's working for instead of against you.
When in doubt, it's okay to choose to just not include your social media links.
Why shouldn't I use skill bars/ratings/pie graphs/fun graphics?
A variety of reasons. Although I am not a recruiter, I've talked about this specifically on social media with fellow professionals that I know backing me up.
A summary:
Sure, maybe you'll get into an interview with skill bars on your resume and the interviewers will comment on how they like them. But how many recruiters zoomed past your application after seeing or misinterpreting them? How do you know they're sending the intended message? Literally no one will hire you instead of the other applicant because you included a fun graphic on your resume. Just...please...skip them.
How do I make my resume stand out?
By having badass art and a traditional, simple, consistent, spellchecked resume. That's it.
Will recruiters judge me if I just use Microsoft Word to write my resume?
Nope. Extremely basic and extremely consistent and extremely spellchecked is perfect. I'd much rather have that than a resume that looks like it's overcompensating.
Any other important things to keep in mind?
Yes: you absolutely MUST have a downloadable PDF version of your resume on your website. NOT just a .JPG or image file. The recruiters need to be able to Ctrl+F text to find keywords on your resume, and they can't do that with a .PNG or .JPG or whatever.
I use Adobe Illustrator to write my resume. You can also use Photoshop/comparable software, Microsoft Word, Google Docs, or whatever fits your preferences.
To help visualize different styles of resumes, this is what the evolution of my resume looks like:

Student resume:
To-be graduate resume:
Professional resume:
***I do not recommend literally just copying the layout of the middle resume because a LOT of people do this when I post it and then recruiters get repeats of this layout. It's offputting. Put a spin on it or come up with something new.***
Whew, okay! Now that we've covered all of that, let's start writing.
Let's break this down into the essentials.
Header

Includes the absolute most important information. Your name, contact information, and the URL to your website. If you're going to break up the information (like I did in the grad and pro resumes, make sure all pieces are extremely easy to find. If you're going to state a title, put it near your name.
Experience

Arguably more important than education (but I might be biased because I think the educational system is a flaming dumpster fire and any job in game art ~ReQuIrInG~ a degree is unnecessary, avoidable bullshit.)
All you REALLY need to include for each bulletpoint is your title, the client/subject, and time period. You can also include task descriptions (remember: no paragraphs!!) and project titles here.
In any section that requires a timestamped list (Experience, Education, Community Involvement), make sure to use the EXACT same format for each bullet point in all sections. This is traditional resume formatting 101. Like this:

As you can see, in each section, I keep things REALLY consistent in formatting. This includes punctuation and spacing. These little details make the difference between sloppy and fantastic resumes. If you move things around in one section, adjust everything else to match it.
Education

Include any degrees or certificate programs if applicable here. If you don't have secondary education experience, you can just include your high school information or skip this section.
You DO NOT need to include your GPA. No one cares about it tbh. Do include minors. I included my time studying Industrial Design because I've found that it's super appealing to recruiters.
Same with experience- make sure to use a really consistent format, especially if you have multiple bulletpoints like I do.
Community involvement/volunteering/"other"

THIS is where you can build a resume with no job experience. This is where that shit IS AT for students. If you don't have a local community...
1. Start something! It can just be 5 people showing up with their laptops once a month at a cafe to work on/share their games/art and get feedback. That's literally all it needs to be.
2. Get involved online! Itch.io game jams, starting a community (with intentional moderation and healthy rules), doing a digital meetup, etc.
Skills/proficiencies/software

Like I mentioned before, DO NOT overcompensate here. Just tell me what you can do. Don't pad this section with unnecessary points. This shouldn't take up a huge section of your resume, it should just inform the reader of what roles you're able to fill, especially if the rest of your resume doesn't clearly state it.
One last thing on layouts:

Make sure to use consistent spacing between sections AND make sure there is ample breathing room between the information and the edge of the page.
WHEW. That was a lot of information.
Use high contrast fonts.
Use OBSESSIVELY consistent formatting.
Don't include social media that you don't want your grandma to see.
Make sure your name, contact info, and portfolio URL are *super* easy to find.
SPELLCHECK, SPELLCHECK, SPELLCHECK.
When in doubt, err on the side of simplicity.
Thanks everyone! Feel free to leave comments/questions/concerns/anything for the good of the cause below. :)
