Factors

There are many things an employer will want to see when they look at you on paper and in person. You will have more control over some factors than others.

Transferable skills – organisation, communication skills etc and being able to provide clear examples of these.
Interaction – how well you get along with others, your ability to work as part of a team and put people at ease when you interact with them.
Adaptiveness – how well you adapt and apply yourself to different tasks and situations.
Experience – do not underestimate/undervalue your skills, identify all your job related skills i.e. different software you can use, volunteering experience.
Education – academic and on the job and any qualifications relevant to the role.
Attitude – your work ethic and how you display this in writing and face to face.
Confidence and humility – not to be confused with arrogance or martyrdom.
Opportunities – awareness of and taking action to find and take advantage of new opportunities.
Networks – building and making the most out of your networks and contacts.
Economic climate – what jobs are available in what industry.
Appearance – both on paper and in person, making sure you and your work are well presented.
Motivation and resilience – how you maintain your motivation to keep applying for jobs, even after multiple setbacks.
You – knowing what you want to do and identifying multiple routes to achieve this.
Your employer and their perceptions – How your employer will make judgements about you, understanding how you will be perceived and how you wish to be seen.
