our newspaper, Washington, June 30 （ReporterWang Youran) A new American study found，Although the Internet provides more information to bet with bet365 seekers and recruiters，But it has not brought more bet with bet365 opportunities to most workers，On the contrary, it intensifies the differentiation of the bet with bet365 market。

The British Emerald Press will publish a new book "Work and Labor in the Digital Age (Volume 33)" on July 4，It includes the article "Black Holes and Purple Squirrels: A Story of Two Online Labor Markets" co-authored by Steve McDonald, professor of sociology and anthropology at North Carolina State University, and others。The author talks about，The Internet and social media have greatly changed the way individuals find jobs，But people are concerned about how the demand side of the bet with bet365 market uses online tools to post bet with bet365 advertisements、Little knowledge about screening candidates。Theoretically，The Internet enables bet with bet365 seekers to obtain more recruitment information，Enable recruiters to reach more hiring candidates。To understand the real situation，McDonald et al. interviewed 61 human resources professionals in two metropolitan areas in the southern United States，They come from a variety of industries across the public and private sectors，Some of them are looking for new jobs themselves。

Visit results display，Although both supply and demand sides can get more information from the Internet，But the Internet has also polarized the bet with bet365 market，At one end are low-paying positions with low skill requirements，The other end is a high-paying position with high skill requirements。bet with bet365 ads for the former category of positions are usually posted on large bet with bet365 search websites，These ads have high “viewability”，Will attract a large number of bet with bet365 seekers，Making it difficult for individuals to find a bet with bet365，It also puts pressure on human resources workers to read and filter massive application materials。Some respondents referred to these types of bet with bet365 ads as “black holes”，Because bet with bet365 seekers are unlikely to receive feedback after submitting an application。The latter type of position usually requires a specific skill set，Called “purple squirrel” by interviewee，Because there are very few candidates who meet all the requirements，As rare as purple squirrels。Recruitment advertisements for this kind of position will also be posted on large bet with bet365 search websites，But in reality recruiters use professional networking sites to find qualified people，These people often already have a bet with bet365 and are not actively looking for a new one。

McDonald said，This study shows that the abundance of recruitment information on the Internet does not mean that willing people can find jobs。The bet with bet365 market is an unequal competitive field，If you are in the "black hole" market，It’s hard to find a bet with bet365；If you are in the market for "Purple Squirrel"，It is more likely that the employer will proactively contact you。In terms of online bet with bet365 search and recruitment，It’s not just the number of jobs posted that matters，Also recruiting strategies and tools used by employers。
