The 26-year-old starred in the MTV reality show between 2006 and 2009 following her breakout stint on Laguna Beach.
"I think the story they told wasn't a dishonest one, [but] the way they did it sometimes was," Conrad told Allure magazine.
"They aren't going to be there for everything. Sometimes two of their main characters will get into a fight, and that's important to the story line. The [producers] need that re-enacted."
Giving an example, she explained: "Brody [Jenner] and I did date. It was pretty brief. There was definitely editing to drag it out."
Speaking of finding fame on reality TV, she added: "I think anyone in the public eye is going to be hated, and a lesson that I needed to learn quickly is that it is impossible to please everybody. One person will call you classy, and another will call you boring.
"People felt that a lot of the things I had were undeserved, maybe because I didn't have a specific talent. I was more of a regular girl and maybe didn't deserve the attention."
Conrad previously admitted that she "didn't love" being in reality TV as it made her feel "uncomfortable".
