How to prepare for a job interview, step by step

By CareerFast · Last reviewed 2026-06-16

To prepare for a job interview: (1) research the company and the role, (2) predict the likely questions, (3) prepare specific STAR stories from your experience, (4) rehearse out loud (ideally in scored mock interviews), and (5) prepare smart questions to ask them. Depth of preparation is the single biggest controllable factor in interview success.

1. Research the company and role

Understand why the role exists, what success looks like in the first 90 days, recent company news, and the culture. This lets you tailor every answer and ask sharp questions.

2. Predict the questions

Most interviews mix behavioural (“tell me about a time…”), situational, and role-specific technical questions. Build a list for your exact role and company.

3. Prepare STAR stories

For each likely question, prepare a Situation–Task–Action–Result story with a measurable outcome. See the STAR method guide.

4. Rehearse out loud

Reading answers isn't rehearsing. Practise speaking them — scored mock interviews tell you exactly what to sharpen and when you're ready.

5. Prepare questions to ask

Strong closing questions signal genuine interest: “What does success look like in 90 days?” “How does this team work with…?”
