Situation is usually already done if you have the right header (employer, role, dates, location). Sometimes additional context is necessary to explain one of these items, in which case you should include more situational information in your first bullet point. For example, maybe you were a web developer for a small startup. It might help the reader to know which industry.
Task is easy too – it should closely resemble your original job description. Use the phrase “responsible for…” if you get stuck, but remember to lead with your best action verbs instead.
Actions are what take the resume to the next level. Instead of simply reading like the job description, actions prove how you accomplished those tasks. Again, think of specific action verbs that explain your process. Integrate as many of your relevant skills as possible to show proficiency.
Results are often overlooked, but help create the best resume content. Think about who you benefited and how. It could be a customer, your manager, or another team. If possible, quantify your results. Use items from your honors and awards. Explain your value. Don’t assume that the reader will know you were successful just by reading what you did – prove it and they will want it too!
Your bullet points should contain combinations of these elements, not each one sequentially. For example, you could lead with a Task and a Result. Next you could have two Actions and another Result. Organize them in a way that provides enough context (S and T), while prioritizing your value (A and R).
Remember, successful job searching is all about storytelling. We can help!
