Proper motivation and commitment:
First of all, you should ask yourself whether you really want this job or not. Is it just the financial benefits or you really want to be a naturalist? You must have a welcoming nature as a lot of interaction is involved in this job. If you are properly motivated and committed then go for it.
Make a CV:
The next thing you need to do is to make an impressive CV. You must follow a regular format of CV to highlight your skills and qualifications tactfully. The most followed pattern is to mention the name at top centre of the page. Then reveal your previous job experience followed by your educational degrees and certificates. Remember to take your time while preparing your CV. Do not forget to put your contact information.
Choose an area:
It is very important to pick an area where you have less competition. Most of the people apply for a naturalist job in cities so it is better to target the small towns as recruitment chances are high there.
Look for the job openings:
Your next step will be to find job openings. The best source of information can be local newspapers, cable channels and recruitment agencies. However, you can contact the management of different schools and ask them for the job. There are also many websites that keep the record of job announcements. It is always better to do some research about your potential employer as this helps you to gain insight into the hiring process.
Send your CV:
After finding a job opening, you should send your CV without delay. Make sure you are dispatching the complete documents otherwise you will get rejected even before the interview.
Prepare for the interview:
You should be well prepared for the interview as this is your best and probably the last chance to get a summer job as a naturalist.
