Some of what you learn – skills and knowledge – will be of immediate benefit to you in this job and maybe only in this job. Overall, however, you should expect that the skills and knowledge that you acquire in this job should be of benefit to you in future jobs.
Specific skills that are really applicable only to the way your current organization does business or builds products or deals with customers may not be directly transferable. All knowledge, however, should be available to be generalized to other circumstances. As you examine what you learn, consider the following:
Is this specific to this organization, or is this something common to companies in this industry?
If specific to this organization, can I determine how other companies do this and how it can be applied more generally?
What are the most in-demand skills and knowledge in your current job, within your industry?
In what other jobs or industries are the skills and knowledge you are acquiring applicable?
