"I am very angry. I'm going to sue Deutsche Telekom and I will force them to pay for everything," the woman was quoted as saying in Croatia's Jutarnji List daily, which only identified her as "Maja."
German daily Handelsblatt reported last week that according to documents it obtained, a woman seeking a job at Telekom's Croatian subsidiary was screened and described as a "very experienced and imaginative sexual partner."
The woman was "known by her friends as a female predator with a seriously elevated sex-drive" and "preferred older men," according to the report.
Maja, who works for the subsidiary Hrvatski Telekom, said she first became aware the case involved her when it was reported in a German newspaper, and later had it confirmed to her from "many people in Germany."
She told Jutarnji List that she would seek possession of the files on her from Deutsche Telekom before pursuing the telecommunications giant in German and probably Croatian courts.
Deutsche Telekom said last week it did not routinely commission reports on the private lives of potential staff, although the allegations are the latest in a series of scandals to have rocked the company.
