It depends upon the size of the company that how much seats will be avilable for employees. Some small companies which have capacity for fifty to hundred persons for work they should hire mostly the experienced persons. On other way some large companies who have capacity for more than five hundred person they should hire both experienced and inexperienced persons.
Some companies think about their future they would hire the young persons mostly because they know that young people deal in a good manner with new technologies. Young people work hard than older ones and also new people will work large time for company. They stay in company for large time also get experience from the older one and work hard for the company.
In other ways the older experinced persons have more knowledge about work than the inexperienced people but at one stage when they are upto fifty then they cannot work hard like youngers so some companies can hire mostly the younger people. In other way to give jobs to inexperienced person can less the rate of poverty in the society. It also stop the crime rate in the society because some jobless people do many wrong things to earn money for food and complete their other uses of life.
In my opinion companies should hire both type of workers experinced and inexperienced because when inexperienced persons work with the experienced person they got a knowledge about work from the older ones and being experinced for future coming inexperinced persons.
