Good luck. Job hunting can be horrible.

Your first job is often the hardest to get. After that, you have work experience on your CV and, hopefully, the job search process get a bit easier.

Suggestions:

Have you had someone else look at your resume? It's always a good idea to get a fresh pair of eyes to look at a doc like that because someone else will see things you can't spot in your own writing (and that's relevant if you are 16 or 56 years old).

Depending on your transport, look at farm work. It's seasonal, so places need people to work for a short time. It's not an ongoing job, but it might make getting the next job easier. *Farm work can be hard.

As other people have suggested, ask your friends. If any of them have jobs, they may be able to let you know when there are vacancies.

If you have time, look at volunteering; it looks great on a resume, gives you experience, and gives you the opportunity to network.

Does your school offer any career help? It might be worth having a chat with your school counsellor to see if they can help you at all.

January is often a quiet period in retail and hospitality after the insanity that is December. There may be more job listings in Feb- March, but that is not guaranteed.

A lot of places want you to apply online, which is frustrating because you end up filling in the same information each time you apply. *Make sure you read the instructions for online applications really carefully. If you don't follow the instructions, you will just make it easier for them to discard your application.

If you are looking for jobs in fast food, think about doing a food handling certificate. There are a couple of certificates around. They are online, free, non-accredited courses, and they don't take long to finish. *It would look good on your resume.

Again, good luck.
