Here are some points to consider:

Tips to Be Successful in Applying:

1. CV Structuring: In my experience dealing with numerous jobs in Zimbabwe, the most critical aspect is your CV. Tailor your CV to highlight any previous experience in a commercial or financial setting, even if it's not directly related to loans. Doing so will show your aptitude for understanding the financial landscape, which is crucial for a loans officer.
2. Job Description Attention: When engaging with vacancies in Zimbabwe, especially in this job offer in Zimbabwe, the job description is a critical area. In this case, it's subtly implied that the job might require extensive interaction with clients and possibly sales or relational skills given the reference to 'marketing'. An applicant needs to bring out any people skills or prior marketing experience they might possess.
3. Education Credentials: Good A-level passes in commercial subjects suggest that the employer values education. Highlight your academic accomplishments especially in the commercial subject sector.
4. Be Prompt to Apply: From my vast experience with job vacancies in Zim, being quick to apply may give you an advantage. No closing date is specified in this listing. Reach out as early as you can.
5. Applying Methodically: While it may not immediately strike the naked eye, the organization has provided two platforms for submissions: email and WhatsApp. Utilize both avenues if possible to increase your chances of your CV being reviewed.

Standing Out in a Flooded Pool:

1. Skills Highlight: To effectively navigate job offers in Zim, going beyond the requirements can set you apart. Showcase financial literacy, loans knowledge, laws and regulations expertise, or customer service experiences. This can increase your visibility in a flood of CVs.
2. Volunteering and Non-Profit Work: Most ngo jobs in Zimbabwe highly value this. Indicating any voluntary work done, especially in financial literacy projects, can give you an advantage in this listing as well.
3. Follow Up: One approach I've noticed over time to make you stand out in a caravan of job search in Zimbabwe is following up. A friendly, professional reminder can put your name at the top of the pile, especially in zimbabwean jobs.

Things Novices Might Overlook:

1. Unspoken Requirements: 'Young energetic people' may suggest they want workers who can handle pressure, have a drive, and are flexible. Evidentially in many jobs in zw I have managed, soft skills are key.
2. Contact Formatting: Novice applicants often forget how important it is to format their CVs. When applying via WhatsApp, ensure your CV is mobile friendly and isn’t distorted when shared on this platform.
3. Company Knowledge: Subtle as it may seem, I've observed, particularly with employment opportunities in Zimbabwe, that doing your homework on the company history, mission, and goals matters. Mention how your skills can contribute to their goals in your application.

Leverage on recruitment agencies in Zimbabwe, as they could guide and help mold your CV and applications to gain a competitive edge. The Zimbabwean job market is always buzzing with opportunities, keep engaging, learning, and applying.
