Today in my country there were job fair and many multinational companies participated. Like 3000 people attended mostly young and the requisite was to present your resume online for the position you wanted to apply., that was it, just collect information and they tell you "We will call you if you fullfill the requirements", imagine to how many people they tell you that only one company. OTher companies ask for experience, mostly in young people and how come a person have experience if you are not given the opportunity to gain the experience.
In the country I live as I believe in other countries as well, after the pandemic the unemployment was high but now still is and ther are people with years of not finding a job and sometimes your studies are not enough to find a job easily, cause working on your own in a total different thing that you may not even have experience and has to start from scratch and not related to what you studied in college or university may give you more chance than to find a job related to what you studied at college or university.
Our company does it. But its on our location not a bunch of companies together. That sounds really beneficial because you can hit many companies and talk to them directly all in one spot.
I suggest you research any company you are interested in. Then you can ask impressive questions at the interview and they will think "Dam this person needs to work here"
