A common occupation is not automatically the best career for every person. Consider these factors before choosing a direction:
Researching several occupations can help you compare realistic options. Informational interviews, job shadowing, volunteer work and short-term courses can also provide useful firsthand experience.
Start by reviewing several job descriptions for the position you want. Identify recurring qualifications, software tools, certifications and responsibilities. You can then prioritize the skills employers mention most often.
Create a targeted resume that emphasizes relevant accomplishments instead of listing duties alone. For example, describe the number of customers you assisted, the value of inventory you managed or the percentage by which you improved a process.
Practice explaining your experience through brief stories. Employers often ask for examples of teamwork, problem-solving, reliability and customer service, even when a position has limited formal education requirements.
