Sure, I'd be happy to assist. Here are the five tips, five areas of note, three standout strategies and three keys areas of the listing to focus on:

Five Tips for Success:

1. Align Your CV: Use your CV to highlight previous experience that's relevant to the duties outlined in the listing such as cleaning, maintenance, or work in a school environment.

2. Demonstrate Your Competencies: Dedicate a section of your CV to outline your competencies particularly attention to detail, ability to work in a child environment and any experience in equipment repairs.

3. Tailor Your Application: Ensure that the job position is clearly stated on the envelope and include a brief cover letter outlining why you're well-suited to the job.

4. Proofread Your Application: Small errors can be seen as a lack of attention to detail, so spend extra time proofreading your application.

5. Sell Yourself: Highlight how your past experiences would make you an asset to the school.

Five Areas of Note:

1. Mailing Procedure: The application must be mailed in to a physical address mentioned. The job applied for should be clearly stated on the envelope.

2. Experience in a child environment: This point suggests that you may be interacting with children on a daily basis, hence, clean records and past interactions with children could work in your favor.

3. Flexible role: Note that the role might include other duties as assigned by the supervisor. Flexibility and open-mindedness are key.

4. Educational & Experience Level: The job requires a minimum of Ordinary levels of education and 2 years’ experience.

5. No Mentioned Deadline: There isn't a specific deadline mentioned to apply for this job, so the sooner you apply, the better.

Three Standout Strategies:

1. Show Passion: Showcase your interest in improving the learning environment can make you stand out in a flooded pool of candidates.

2. Validation: Have solid references who can vouch for your skills and your ability to work in a child environment.

3. Unique Selling Proposition: Identify unique, value-adding aspects about yourself that align with the role's needs. Possibly, experience working at similar such jobs in Zimbabwe or any NGO jobs in Zimbabwe.

Job Listing Analysis:

1. Interaction with Children: The callout to an ability to work in a child environment may be underappreciated. In my experience, personnel who interact well with children are highly valued in a school setting.

2. Flexibility: The mention of "any other duties assigned by the supervisor" hints at a flexible role, potentially requiring multifaceted abilities.

3. School Setting: Over time, I've observed applicants not giving enough emphasis to the context. This applies equally to job vacancies in Zimbabwe or anywhere else. The job is at a school; your contributions will directly impact children's daily environment and learning experience.

Remember, in your job search in Zimbabwe or your pursuit of job vacancies in Zim, always align your skills, values, and experiences with the specific role and the organization.
