After reviewing the company values and job description, it’s useful to create a list of stories from past experience which exhibits the listed behaviour.
Let’s assume you are applying for a Senior Software Engineer role at Meta, we know that they want people who move fast, focus on long term impact, are direct and respectful to colleagues. So, you can search for examples from your past about a high priority/impactful project that you completed in time, gave direct feedback to colleagues/manager that was well received and helpful or how you showed empathy towards your teammates, helped resolve conflicts, showed leadership skills, etc.
For Amazon, customer obsession, ownership, high standards, frugality, delivering results are vital. So you could talk about past experiences where you went beyond the expectation to help a customer, looked at the bigger picture and not just focussed on you/your team, didn’t shy away from your responsibilities, projects that show how you maintained high standards in terms or your work and people around you, how you have achieved more with less and delivered results time after time.
