Maguire entered British television series The Apprentice in its fourth series as a 27-year-old marketing consultant, who says that when she first ran an office, she made £60,000 in six months with no training. She described herself as "the best saleswoman in Europe at the moment". The media portrayed her as "an ice maiden" and as resembling "someone frozen alive while chewing a wasp". She was fired in week 7 along with Jenny Celerier.
After leaving The Apprentice Maguire returned to Ireland. She has since embarked on a successful television career. In August 2008, she participated in the Raidió Teilifís Éireann (RTÉ) reality television show Fáilte Towers, where she reached the final. During the show she went to Castle Leslie with fellow contestant Don Baker. She has also been on radio with Ray Foley on Today FM.
In March 2009, Maguire was believed to be running a chain(two) of photography studios in Ireland.
She presents the long-running satirical clip show Republic of Telly on RTÉ Two. She was going to leave it to return to the UK in 2011 but decided to stay in Ireland and continue her work on the show. She notably rendered Ryanair chief executive Michael O'Leary speechless on this show when she asked him: "What's it like being the biggest prick in Ireland?" She has also recommended to Marty Whelan that he retire, accused Gerry Ryan of being "too old" for the Meteor Music Awards and queried if Gráinne Seoige cringes while watching The All Ireland Talent Show.
In September 2011, she was subjected to a mix-up when her pictures mistakenly appeared on the website of model agency Assets.
In 2012, she presented online TV show Snug TV.
