Sure, here's my input:

Tips to Apply Successfully:

1. Structure your CV: In my experience, the first chance to make an impression is your CV. Ensure your CV is tailor-made to fit this role. Highlight your experience in the 'ECD A' and 'ECD B' teaching positions, specifically focusing on tasks and achievements related to this.
2. Emphasise on Location: It seems important to this organization that you reside in the Ruwa/Zimra area. If you do, make sure this is clearly mentioned in your CV.
3. Mention your License: A clean class 4 license is a requirement, remember to mention it in the skills or qualifications section of your CV.
4. Proven Experience: Clearly present your at least '2 years of proven experience' in the relevant field in your CV and cover letter.
5. Highlights of Job Posting: The job posting specifically instructs to mention the role you're applying in the subject line of email. Adherence to such small yet significant instructions subtly demonstrates your attention to detail.

Important things to Note for Applicants:

1. Deadline: Take a note of the deadline, i.e, 'the 30th of November 2023'. Missed deadlines are one of the most common mistakes I've seen over time. Always double-check these details, as jobs in Zimbabwe have very strict deadlines.
2. Requirements: Even if you don't meet all the criteria, you can still apply, but be ready to justify and demonstrate your willingness to learn and adapt during the interview.
3. Application via Email: The job listing specifies the email to send the CV, and it requires the position to be stated in the subject line. This is a common aspect that job vacancies in Zimbabwe take seriously.

Ways to Stand Out:

1. Specificity of Skills: Be specific about what your skills are and how these would directly benefit the organization.
2. Include relevant Certifications: In this competitive world, job offers in Zimbabwe don't just want experience, they want updated knowledge in the field. Showcase any ECD-centric certifications or trainings to stand out.
3. Tailor-make your Cover Letter: A cover letter is your ticket to standing out. Tailor yours specifically to this role addressing how you can fulfill the 'duties and responsibilities' mentioned in the post.

What the Organisation is looking for:

1. Local Candidates: The organisation's preference for candidates from Ruwa/Zimra area clearly indicates they probably want someone who knows the local dynamics, is easily available and will have reasonable commutes. Often overlooked, this is a key point to note in the job vacancies in Zim.
2. Proven Experience: A demand for 'proven experience' depicts their need for a candidate who can hit the ground running without needing initial hands-on training. This is evidence of the competitive nature of the vacancies in Zimbabwe.
3. Class 4 License: A clean class 4 license requirement shows that there might be some driving involved in the job. Candidates who can't fulfill this requirement should consider this point seriously before applying.

Generally speaking, jobs in zw are competitive and thus, require keen and careful applicants who are ready to go beyond the ordinary to stand out. All the best!
