Sure, I'll be glad to assist you with this. Here's my advice, bearing in mind the wealth of experience I've gained while working with various industries over the years.

Tips for Applying

1. The Right Qualifications: Ensure your CV clearly shows your degree or HND in Sales & Marketing or a related field. In my experience, firms appreciate candidates who tailor their CVs to match the job requirements.
2. Relevant Work Experience: Highlight at least three years of suitable work experience on your CV, preferably in an engineering or manufacturing setup.
3. Essential Skills: Highlight in your CV your ability to work with minimal supervision, your good communication and interpersonal skills. In the world of marketing and sales, these soft skills are just as crucial as hard skills.
4. Achievements: Underscore your past successes in meeting sales targets or generating revenue for past employers. These paint a picture of what you're capable of achieving for potential employers.
5. Driving Licence: A clean Class Four Driver's License is required. Make sure this detail is included in your CV if applicable.

Areas of Greater Note

1. Application Date: Please note that all applications must be submitted by the 15th of December 2023.
2. Application Procedure: Send all applications to the provided email and clearly mark 'Sales Representative' in the subject line. What I have noticed overtime is that many candidates lose job opportunities simply because they do not follow the set submission procedure.
3. Limited Communication: The job listing indicates that only shortlisted candidates will be contacted. This could take time, so patience is key.
4. Don’t Ignore Peripheral Requirements: Experience in an engineering and/or manufacturing setup gives you an added advantage. Even if you don't possess this, make a case for how your specific experience will complement the job.
5. Look for Zimbabwean Job Platforms: Seek employment opportunities in Zimbabwe on platforms which post jobs in Zimbabwe frequently.

How to Stand Out

1. Industry Understanding: Show an acute understanding of the manufacturing and engineering industry as it is a distinct advantage. Demonstrate an ability to quickly learn and adapt to industry changes.
2. Superior Communication Skills: Your CV, and later your interview, should demonstrate excellent communication and interpersonal skills.
3. Targeted Cover Letter: Create a detailed cover letter explaining why you're uniquely qualified for the job, budget for time on this as most candidates neglect cover letters thereby missing the opportunity to stand out from the crowd.

Things Novice Applicants May Miss

1. Keyword Usage: Many novice applicants ignore keyword usage in their CVs. The relevant keywords here include 'Sales Representative', 'engineering setup', 'manufacturing setup', and so on.
2. Soft Skills: Many underestimate the importance of soft skills. This job listing emphasises the need for a self-starter and someone who can work with minimum supervision; it's crucial to not gloss over these.
3. The Email Subject Line Requirement: Novice applicants often overlook little details in job listings like including the job title in the subject line of the email.

Remember, the job market, especially for job vacancies in Zimbabwe, is getting increasingly competitive. Stand out by observing the above-mentioned points. Recruiters and recruitment agencies in Zimbabwe heartily welcome well-prepared candidates. Best of luck with your job search in Zimbabwe!
