She turned her internship into a full-time gig and has been climbing the ranks in the out-of-home advertising industry for the past 36 years.
If you want to turn any internship into a full-time position, "treat it like a really long interview," the executive tells CNBC.
"Don't just address an internship as a temporary thing, a transient opportunity that's part of your path to a career somewhere else. Really treat it like an amazing opportunity and delve in.
"Get to understand the business, bring as much value to the organization as possible, and become a valuable member of the team," she says.
Treating an internship like an interview means continually proving your value, Senese says: "Don't ask, What can the company do for me? The question should be, What can I do for the company?"
This not only means "working harder than everyone around you," she says, but "the other piece is to always be thinking. From very early on, I was always iterating new ideas and new ways to do things."
To do this, you have to be aware, interested, and well-read, she says, which is why her go-to advice to interns is to stay up-to-date: "Make sure you read the newspaper, make sure you're up on current events, make sure you know what's going on in the world."
Self-made millionaire Marcus Lemonis agrees on the importance of always being informed. The entrepreneur reads the local and national newspapers on a daily basis, he tells CNBC: "Whether that's The Wall Street Journal, The New York Times or your local paper, I think in order to get in touch with real-time information, you've got to study real-time data."
After all, "if you're going to make business decisions and you're going to make them today, you might as well have the most recent information," says Lemonis.
