Step-by-step explanation:
The first block of information shown in your resume is the heading section. This section is at the very top of your resume and includes your name and contact information. It's critical because this is the first thing a potential employer or admissions officer will see. Following the heading section, you might choose to include a career objective or summary that briefly states your professional goals and what type of position or program you are seeking.
It is important to ensure that your contact information contains a professional email address, as well as current details for how you can be reached. Your resume should be a concise, one-page document that is easy to read and clearly formatted, showcasing your most relevant qualifications and experiences to the reader.
