1. Chronological Resume.

This format is common, and it’s identified with a listing of employment history starting with the recent position listed on top. The other positions held before that are listed in reverse order. Most employers prefer to use this kind of resume as it provides an easy way to retrieve information on employment history of a prospective employee. Also, it enables them to fast track what kind of jobs one has done and the flow of time concurrently. This resume format is considered the best for job seekers with a wide range of employment (Bennett, 2014).

2. Functional Resume.

This type of resume is skills and experience-oriented. Contrary to a chronological resume, which starts with work history, the functional resume starts with professional experience and skills acquired over a while. It also has a resume summary composed of details and information on personal achievements and skills. According to Doyle (2020), this type of resume does not contain sections regarding employment history at all, or sometimes the work history is provided at the bottom of the resume. Again, it is preferred by people who have gaps in employment history or changing careers. More often, it suits those who are yet to be employed and those who have low experience, and therefore by just considering their skills, they meet the qualification.

3. Combination Resume

According to Doyle (2020), a combination resume is a hybrid of functional and chronological styles with skills listed on the top of the resume and employment history, which is not relevant. This type of resume is skills-oriented, even though it also allows employers to evaluate one's employment background. Therefore, it helps the employer know the necessary skills from the prospective employee through extensive information (Schramn & Dortch, 1991).

Walmart is the Leading Supply Chain Retail

Walmart's supremacy in the supply chain began in 1962, and ever since, the giant store has been known for its low consumer prices. Over the years, it has become the best retail worldwide, having numerous outlets with different names. According to Wal-Mart (2012), effective packaging and branding mechanisms have ensured low prices to customers since suppliers adopt a universal packaging system. Consequently, the retailer has been able to cut costs, thereby influencing the best prices for customers. Similarly, the packaging strategy has been considered to be effective in reducing the cost of supply. The reduction in packaging size and increasing reusable packaging ensures many goods are shipped while reducing the number of carriers, thus cutting costs on energy or fuel (Kamal, Sharif & Love, 2017).

The retailer has a large and epic inventory with various goods and has innovated their supply chain through technology investment, which ensures planning, forecasting, and replenishing system is in place to run their operations effectively. The use of Universal Product Code for barcodes for products and use of Bentonville database displays real-time sales data across their stores. The use of technology has enabled them to work perfectly by reducing human error; therefore, proper forecasting and planning enabled them to execute their programs promptly. Through collaboration and data sharing, Walmart has campaigned to promote data sharing across the stores, distribution centers, and manufacturers to enhance forecasting (Ali, 2012).
