is that it is preventing you from finding one now

One of the areas in which the use of AI has had the greatest impact has been in the ATS automatic filtering systems of candidates (Applicant Tracking System) of the personnel selection processes, and in general throughout the process including interviews. When AI began to be integrated into these processes, it was done thinking that this technology would streamline screening and selection of the best candidates. However, the use of this technology has led to the collapse of the entire process: neither those selected are the most suitable, nor should those discarded be. As technology journalist Tim Rogers laments in an article published in Slate: the hiring system “is broken.” Sending resume is a waste of time. Rogers said that looking for a job is no longer just a matter of updating your resume and sending it to companies looking to fill their vacancies: automatic systems and artificial intelligence have created an invisible wall that makes it even more difficult to get a real opportunity. The problem is that ATS systems, which in theory should make the selection of candidates easier, now filter and discard hundreds of resumes with rules so strict that many candidates never get to be reviewed by a real person and, therefore, a factor that many CEOs of large companies are missing they are claiming as priorities: attitude and commitment. A system blocked by saturation. According to data According to the World Economic Forum, 80% of companies use some AI system in their recruitment processes. The direct consequence of this automation, which occurs both from the human resources departments and from the candidates themselves, is the saturation of applications and the opposite effect that was expected to be obtained: the selection processes are becoming increasingly longer and recruiters can’t cope to review so many profiles. According to report figures ‘Huntr Q2 2025’, the average time elapsed from the beginning of a job search to receiving the first offer has increased by 22% in just three months, going from 56 days to 68.5 days. The data indicates that the main employment platforms, such as LinkedIn or Indeed, concentrate around 80% of the applications and, even so, their response rate is around 3.3%, which shows that the vast majority of applications do not even manage to attract the attention of a human recruiter. AI plays both sides. Faced with the use of AI in their application filtering systems by recruitment platforms, job seekers have not stood idly by and have also They have used AI to optimize your requests. So they told it from Manfred, who published on their blog that, until recently, they received between 20 and 50 applications for each vacancy they opened. Currently, the same job posting can return 500 applications in the first 24 hours, with most of them generated by AI. As they point out, this avalanche of requests is not due to the fact that there has suddenly been a fivefold increase the talent availableit has only been automated. You hire a profile, not a person. Rogers lamented that automated candidate filtering left out of the process profiles that, in human hands, could be a perfect fit and provide value. “Quality is lost among thousands of documents generated by machines,” the journalist wrote. “We are sold the idea that AI can fix the mess it has created,” warning that this strategy only intensifies the problem and further triggers the digital noise that makes it difficult to really be seen by an employer. Amid frustration over the lack of human treatment, the journalist maintains that “in-person contact continues to be the most effective way to get an interview. The few opportunities I have gotten did not come from algorithms, but from people,” a literal statement based on his own experience. The data proves him right. According to the data collected According to the INE in the 2nd quarter of 2023, 57.5% of people search for employment through their network of contacts. According to Eurostat data As of 2020, Spain does so in 72.6% of cases and Italy in 77.5%. Our neighbors in France use their network of contacts in 63.5% of cases and Portugal in 65.7%. An infinite circle that leads nowhere. Rogers points out that the reliance on AI-automated processes has led to a vicious cycle where “machines write resumes and other machines evaluate them,” reducing the job search to a kind of profile puzzle in which the best fit does not necessarily have to be the most suitable for the position or the team with which you will work. The last experiences with hiring of this type have shown that one of the few reliable avenues for recruitment remains the face to face interview between the candidate and the recruiters. In fact, companies like Google and Amazon are already demanding that their new candidates have a face to face interview to prevent AI distort real capabilities of the candidates.

How to improve Chatgpt’s privacy preventing what you write is used to train artificial intelligence

Let’s explain How to improve Chatgpt’s privacydeactivating the option with which you allow OpenAi to use all the content you write or believe to continue training its artificial intelligence models. It is an option that is activated by default in your profile, but it is easy to disconnect. When you are using chatgpt, if you don’t change anything you are giving the company permission to collect your interactions. Then, these questions that you have asked the AI ​​and the answers generated for you will be used in the future to continue training and improving the models. But if you don’t want this information to be used because it is private, we will tell you how to deactivate it. Disable data sending to chatgpt The first thing you have to do is enter the configuration of Chatgpt. For that, on the mobile click on the side options button and click on your username.

In the desktop versionwithin the configuration click on the section of Data controls. Once inside, click on Model improvementwhere you will be able Disable the option Improve the model for all That will appear in the first place.

clothing that instead of preventing you from cooling, heats up

Few things are comparable to sunbathing to warm up. Solar energy is directly or indirectly, the source of all the energy we use on Earth but, perhaps above all, it is a source of heat. Now a team of researchers has developed a fabric capable of taking advantage of solar energy in a different way but with a very conventional purpose: to warm up. Up to 30º. It is an “intelligent fabric” capable of heating up to 30º Celsius. For this, it is only necessary to let this material exposed to sunlight for about 10 minutes. Its developers point out that the new invention could serve to create ideal clothes to resist very low temperatures. Clothing, 2.0. Conventional clothes, as we can intuit, do not heat. At least not in the sense of emanating heat that our body absorbs. What he does is rather help us not lose heat that, naturally, emanates our body. It could be said that it keeps us hot instead of warming us. In 2025 there are clothes that are able to warm us: gloves, coatsblankets and to accessories. However, these types of designs require energy sources such as batteries or plugs, which limits their “autonomy.” Resistant and flexible. The new system allows to avoid the fattening and risks associated with this type of garments by heating ourselves with surprising efficacy. But in addition to this ability to warm us, the developers of this material highlights its durability and elasticity. As they explain, the new material is able to stretch up to 500% and support 25 washing cycles without losing its heat property or its appearance. Nanoparticles The “magic” behind this material “(is in nanoparticles that) are activated by sunlight, allowing the fabric to absorb heat and transform it into warmth,” Explain in a press release Yuning Li, one of the developers of the new material. The new fiber, their creators point out, is created through a wet spinning process, combining polypamine and polyianylin nanoparticles. This facilitates the absorption of light and improves photothermal conversion. The team responsible for ingenuity presented the new material With an article In the magazine Advanced Composites and Hybrid Materials in which he offered some details about this. Is it loaded? Another unique characteristic of this fabric is that it changes color depending on its state, that is, when it is “loaded” of energy acquires a different color. This is also due to the nanoparticles responsible for storing and releasing energy in the fabric. A feature that is also useful as an indicator of the “load status” of the garment in question. Of course, the question of when and how we can see this finding implemented in our locker room is one that remains to be answered.
