There are a few different types of training that most companies offer. The most common type of training is on-the-job training, which is when new employees are trained by being given specific tasks to do under the supervision of an experienced employee. Many times, this type of training is combined with classroom instruction, where new employees learn the theory behind what they will be doing on the job. Some companies also offer off-site training, where employees go to a different location to receive more in-depth instruction from experts in their field.
