Career days may make great opportunities for talented graduates who want to gain valuable experience. In the light of the small number of recruiters, many would suggest that career days for low GPA graduates may limit their opportunities.
I believe, every person has a favorable niche for himself, in this universe. Only thing is, he has to discover it ! And how a person will discover it, differs from person to person. True that there may seem to be less opportunities for low GPA graduates, they nevertheless, have to try their lucks at whatever skills they may possess, so that they stand tall and efficient!
@Mahfuz, Career Days are devoted to all students! Behind marks, there are many other influential factors like @Tiia mentioned, like personality, skills, sociability, friendliness, openness, communication, etc., and the prospective employer would take all into account!
Basically, it is getting to know people who are decision makers. An employer looks at a career day as an event where they can meet a large number of qualified, potential candidates. A job seeker might look at it as an event where they can go develop some relationships that will lead to getting a job. It is important to note that very few people actually leave graduation with a job! Career day is an opportunity for you to do some networking to assist you in getting that great job.
Tiia hit the nail on the head: in business it is the persona that counts (not as much intelligence, fortunately or unfortunately). One of my sons, highly placed in business, does much of his connecting with possible clients in a social club!!! We as academicians may find this style of living antithetical to ours, but we need to accept it as a worldwide reality. Therefore, by all means open career days to all students.
I encourage all of my students to attend Career Days as well as other networking events. Any opportunity to make connections is valuable. As many have said, these are opportunities to explore options, gather information, and make connections. Employers are not only looking for candidates that have stellar GPA's, they are also looking for talented individuals who can meet their organizational needs and can demonstrate energy and enthusiasm, that they are able to adapt their academic learning to the work place, strong communication skills, leadership skills, and a willingness to work as part of the team to accomplish organizational goals. Participating in these kinds of events is excellent experience and exposure. Everyone should attend.
It is important to make contact with reality and the future. Information is a valuable resource worth getting so that later you don't regret choosing a path which does not suit you. So yes, average or below average graduates need to attend career days either to see that they don't like a future in the field (too hard, too unsatisfactory, too boring) and re-specialize for something else, or to see that it is a road worth following and to start building up a proper CV working at smaller companies or institutes, then moving up to the big players.
School is different than industry or research and even top graduates may find the future career opportunities unsuitable for them and change field (like going into the banking system, or IT sector).
The way you graduate only shows your abilities as a student, not as an employee. I personally know a few people which were able to be top graduates in certain fields, but this does not mean that they would have enjoyed careers in those areas, just that they liked being students and had impressive learning abilities. Also, I know average or lower graduates who managed to get jobs in their specialty and then got very good at what they're doing.
Again, information is good both for recruiters and career seekers.
Having spent a year in a U.S. law school, I can see another reason for opening the doors of career days to all students. Law students who earned outstanding grades became law professors. Law students who earned above-average grades became lawyers. Law students who earned mediocre or below-average grades became politicians. It follows that there is a profession for everyone, no matter what his grades.
