It is no longer impossible but as far as entry level positions go for those that need their first ever jobs, not everyone has the privilege of going straight onto college or university after completing high school. And as far as formal job requirements go, not everyone has the right skillsets to begin with. One of the best job opportunities for high school leavers across the world will be that of working as a data center operator or clerk.
But high school never prepared the young school leaver adequately enough. Major companies across the globe recognize such shortfalls while at the same time needing to fill those positions. To this end there are those companies that are more than willing to sponsor or contribute towards the running costs of the required online data center operations training courses. This of course is to the advantage of the potential new recruits.
Because to begin with, where would they have the money to fund their required training in the first instance. Data center operations training is a step by step process. Training is ongoing but need not last longer than a few weeks. The advantage of the online training portal is that recruitment candidates are able to process their training at their leisure. This works well when you consider the circumstances of those who still need to get up every morning to attend to less rewarding but more taxing jobs just to put food on the table.
But both public enterprise and privately run companies may also recognize that many jobseekers do not even have the very basic skills to work a computer. And so to this end more direct interventional training is required and the online convenience really has to take a backseat.
