In a 2017 Careerbuilder survey of 1,018 users of the job site jobs.de, 35.2 percent rated du in job ads as negative and wenig wertschätzend, showing little respect. 26.2 percent liked it, and 38.6 percent said it made no difference. In 2019 researchers in Osnabrück surveyed 1,306 people aged 15 to 65. The participants did not prefer applicants to be addressed with du, either in the job ad or in the job interview.
