There are many benefits to using ChatGPT on your resume: It can help with grammar and spelling. It can help optimize your existing resume for a role you're applying for. And if you're starting from scratch, it can be a good way to get a first draft of your resume going.

"If you have writer's block," says Amanda Augustine, career expert at TopResume, if writing your resume "seems like the most overwhelming, daunting project," ChatGPT can give you some material to start with. Augustine spoke with CNBC Make It at the Fast Company Innovation Festival, where she gave a presentation.

ChatGPT "gets the creative juices flowing," she says. Still, there's one major problem with using it: You never know if what it spits out after a prompt is going to be true.

'It is going to hallucinate information'

ChatGPT is "the ultimate people pleaser," says Augustine. Whatever prompt or task you give it, it will always give you some sort of response.

"It is going to hallucinate information and it is going to take leaps of faith," she says. "It's going to attempt to fill in the blanks," even if it fills in those blanks incorrectly. If you ask ChatGPT to write out your resume without giving too many details, it could invent bullet points and accomplishments under some of your previous roles, for example.

"The more blanks you fill for it," she says, "the less likely it's going to give you inaccurate information."

'If you don't know the answer, say you don't know'

Beyond just feeding it very specific information to ensure accuracy, there are also certain commands you can give ChatGPT to ensure it doesn't "hallucinate" an answer. Here are three prompts Augustine suggests using:

• If you don't know the answer, say you don't know.
• If you don't have that data, say you don't know.
• If you don't have that statistic, say you don't have it.

For instance, you can prompt ChatGPT to get some resume help by saying, "give me a list of the most common responsibilities of blank person at this type of company," says Augustine, then add, "if you don't know the answer, say you don't know." Some of those responsibilities may be relevant to your previous experience and give you fodder to work with — but not if they're not true.

Remember, when it comes to ChatGPT and your resume, "you're never relying on this alone," says Augustine. "It's one of many tools."
