To get a new job you often need a new set of skills.
In a nutshell you need to know the skills you need and you need to know the skills and experience you have. The difference between the two is where you should focus your learning.
As simple as that sounds, it’s very rare that people act upon it and hence they have skills gaps which need filling. Once you know what the gap is you can start to put plans in place and a schedule of learning.
The earlier you become aware of the skills you need, the more chance you have of obtaining these skills ready for when you’re job hunting.
