A tip I give any newbies, from someone who has been employing pilots for around 30 years, is to understand the importance of showing that you will get on with everyone else in the team and clients, suppliers etc. and that the customers will feel comfortable with.
This can be demonstrated by things other than your flying experience in the CV. eg previous work history, travel, volunteering etc, or just having some hobby or skill that really makes you stand out as an interesting, innovative person that you'd like to spend time chatting with on a slow day.
There are some who come out of certain training environments who have a superiority complex. Having them constantly saying how their inner city sausage factory did things SO much better will end the career very quickly.
"That guy is a ********" is mud that will stick for the rest of your flying life! Be professional but also be good company and remember that good communication skills are essential in any type of employment. This doesn't come naturally to everyone and is a skill many need to work on.
Good luck!
