Mrs Clinton used a private email server for her government and personal emails rather than the State Department’s email system during her tenure. The FBI has been investigating if sensitive information was mishandled.
The agency interviewed her for more than three hours on Saturday and Mrs Clinton told NBC’s Meet The Press that she was pleased to have the opportunity to assist the department bringing its review to a conclusion.
She described the tone of the FBI session as civil and businesslike.
Mrs Clinton said she had no knowledge of any timeline for the review and would not comment on whether she was given an indication that charges would not be filed.
For Mrs Clinton, the interview indicates that the US Justice Department’s year-long probe is drawing to a close, only four weeks before she is set to be formally nominated as the Democrats’ choice to succeed President Barack Obama.
The interview with NBC’s Chuck Todd will be shown on Sunday.
In a tweet on Saturday, her Republican rival Donald Trump said, “it is impossible for the FBI not to recommend criminal charges against Hillary Clinton. What she did was wrong!”
But Mr Trump also created his own stir on social media by posting online an image of Mrs Clinton with what appeared to be a Star of David and a background of dollar bills.
He took Mrs Clinton’s old Twitter avatar celebrating her status as the first presumptive female presidential nominee and added a background of dollar bills along with the words “Most Corrupt Candidate Ever!” written over a six-point star.
The image quickly drew scrutiny online, raising accusations of anti-Semitism. Mr Trump deleted the tweet later in the day and replaced it with a version that uses a circle in place of the star.
Meanwhile, Bill Clinton sparked controversy by meeting US attorney general Loretta Lynch on an airport tarmac in Phoenix, Arizona, on Monday when their travel schedules coincided.
Ms Lynch said their discussion did not include the Justice Department investigation of Mrs Clinton’s email server.
An aide to Mr Clinton said his conversation with Ms Lynch was unplanned and entirely social in nature.
Clinton and Lynch said they would not speak again during the campaign.

US presidential candidate Donald Trump is a feminist who has “lived” gender equality, his daughter has said.
Ivanka Trump said that the polarising Republican hopeful had “employed women at the highest levels” of his businesses.
Her 70-year-old father has consistently polled badly with women in the US in the recent months of the election campaign, which comes to a head in November’s election.
But Ivanka, 34, who works on his campaign, told the Sunday Times that her father’s feminism was “a big reason I am the woman I am today”.
