Surely. In my extensive career as an employment consultant, I have analyzed thousands of job listings. Here is what I interpret from this job advertisement, and how applicants can use this information to be successful:

5 Tips to be Successful:

1. Highlight your relevant skills: The employer emphasizes the importance of excellent customer service. In my experience, the first section of your CV should have a brief account of your customer service experience.
2. Showcase punctuality: Another important trait in this job is punctuality. In your CV and cover letter, provide instances where your punctuality was pivotal to your job performance.
3. Recognize the importance of safety regulations: Owing to the nature of this job, knowledge in health and safety regulations will be vital. Do not forget to list any relevant certifications or experiences.
4. Emphasizing your qualifications: The requirement is for those with a Zera Certificate and a minimum of 5 O levels. Make sure these qualifications are easily noticed in your CV.
5. Be relevant: The recruiter is interested only in relevant applications (Zera certificates only). Keep your CV focused and specific to the job role and its requirements. Avoid adding unnecessary details.

5 Areas to Note:

1. Prerequisites: The employer has clearly mentioned Zera Certification and a minimum of 5 O levels as prerequisites. Only apply if you meet these criteria.
2. How to apply: The application should be sent via email or WhatsApp on the given number. Follow these instructions.
3. Attach your Zera Certificate: In my experience, failure to attach necessary documents may result in your application being rejected. Ensure your Zera Certificate is attached.
4. Deduce from the contact details: The use of Gmail and a mobile number suggests it’s a small-to-medium enterprise. Tailoring your application with an understanding of the organization's scale and needs, might well position you.
5. Closing date: While it's not directly stated in this job posting, most vacancies in Zimbabwe have a closing date within one to two weeks of advertisement. Ensure you apply promptly to avoid disappointment.

3 Tips to Stand Out:

1. Be relevant to the job: In a pool of job seekers, the most relevant application stands out. Tailor your CV to match the job requirements.
2. Show your readiness: With the contact details provided, you may consult prior to applying. Show your interest, ask relevant questions. This could make you noticeable.
3. Certifications: If you have other relevant certifications besides the required ones, consider sharing them.

In job search in Zimbabwe, I've noticed that three important things most novice applicants will likely either miss or not give enough importance to are:

1. Grammar and Spelling: Simple spelling errors (like "puntual" instead of "punctual") can cause an application to be discarded. Ensure your application is free from such errors.
2. Underestimating Small Organizations: In a job market with various employment opportunities in Zimbabwe, both small and large organizations offer valuable experience. Don't dismiss opportunities from smaller companies.
3. Follow Instructions: The instructions for how to apply are clearly given. Failing to follow these instructions can lead to immediate rejection, regardless of qualifications.

Remember, the key to securing jobs in zw is to observe both obvious and implicit language, and tailor your application accordingly. Do consider reputable recruitment agencies in Zimbabwe which can aid in your job search in Zimbabwe. I wish you the best in your applications for Zimbabwean jobs.
