1. Conditional structure: "what you wear should depend on the company's culture" uses a modal verb "should" to express advice or recommendation, which is appropriate for IELTS Speaking.
2. Present simple tense: Used throughout the answer (e.g., "tech startups...have a more casual dress code," "you show that you understand...") to state general truths and habits.
3. Infinitive of purpose: "to match your outfit" and "to research the company" use the infinitive form to express purpose, which adds clarity and fluency.
4. Modal verbs: "might seem out of place," "should depend," "you'll probably feel"—these modals express possibility, advice, and likelihood, making the answer sound natural and nuanced.
