I recommend that you look for vacancies on company websites, on social networks, on forums about work and employment, etc.
I was recently looking for a job as a bank teller. I found a vacancy on the bank's website. The requirements were high, but the working conditions and stable salary attracted me.
After you have found a vacancy, you will need to send a resume and a cover letter. This must be mega cool! Believe me. There are many candidates, but few vacancies.
I turned to an online resume writing service and a teller resume
was prepared for me. It worked! I was invited for an interview and then I got the job.
