The complete checklist — phase by phase

14+ days before
Research phase

Read the full job description 3 times. Highlight keywords and required competencies.

Research the company: mission, product, recent news, business model, competitors.

Find recent interviews or talks by the CEO/founder — what's the strategic focus?

Research your interviewers on LinkedIn if you know their names.

Join relevant communities (LinkedIn, Reddit, Glassdoor) to find recent interview reports.

Map the company's interview process — number of rounds, format, known frameworks.

7–14 days before
Story preparation

Write out 8–10 behavioral stories using the STAR framework (Situation, Task, Action, Result).

For each story, tag which competencies it covers (leadership, conflict, failure, innovation, etc.).

Prepare your 'Tell me about yourself' answer — 90-second career arc with forward hook.

Prepare 3 'Why this company?' points that are specific and research-backed.

Prepare 3 'Why this role?' points connected to your career trajectory.

Prepare your salary expectation range using real market data.

3–7 days before
Practice & mock sessions

Run at least 2 mock behavioral interview sessions out loud — not just in your head.

For technical roles: complete 10–15 relevant practice problems or case studies.

Record yourself answering the top 5 questions for your role. Watch it back.

Time your STAR answers — they should be 90–120 seconds each, no longer.

Prepare 5 intelligent questions to ask interviewers (not HR questions — strategic ones).

Get feedback on a practice session from Zari's mock interview coach.

1–2 days before
Logistics & final prep

Confirm the interview time and time zone with the recruiter.

Test your video/audio setup if it's a remote interview.

Print or have your resume open on a separate screen.

Prepare a notepad for taking notes during the interview.

Skim your top 5 behavioral stories one last time.

Read recent company news or product updates — something to reference.

Interview day
On the day

Log in or arrive 5 minutes early, not 30.

Have your resume and key notes visible (for virtual: on a second screen, not printout).

Drink water before — you'll need it during long loops.

Listen fully before answering. A 2-second pause is fine. Rushing looks nervous.

Ask your prepared questions. Interviewers remember candidates who ask smart questions.

Note any names and details mentioned — useful for follow-up.

Within 24h after
Follow-up

Send a personalised thank-you email to each interviewer within 24 hours.

Reference a specific conversation topic from the interview — not a generic template.

If you felt a question went poorly, a brief follow-up via email can address it.

Reflect on what went well and what you'd improve. Document it.

Follow up with the recruiter if you haven't heard within the stated timeline.

The 5 most underrated interview prep tasks

1
Record yourself answering questions

Nobody knows how they sound until they hear themselves. Filler words, rushed delivery, and vague answers are invisible until recorded. Watch 2 recordings and your self-awareness jumps immediately.

2
Research your interviewers, not just the company

Check each interviewer's LinkedIn. What did they work on before? What articles have they written? A question like 'I noticed you worked on the payments rewrite in 2022 — what was the most surprising challenge?' signals preparation that generic candidates don't do.

3
Prepare smart questions — not HR questions

Not 'what does success look like in this role?' That's an HR question. Instead: 'What's the biggest open problem the team is trying to solve right now that I'd be working on?' Specific, substantive, shows genuine interest.

4
Know your salary range before the first call

Salary questions come early, sometimes in the first screening call. Know your number, range, and the market data backing it before you pick up the phone. Being unprepared here costs you thousands.

5
Practise STAR answers out loud, not in writing

Writing your stories is step 1. Speaking them fluently is step 2. The gap is larger than you expect. Run at least 3 spoken practice sessions — with a partner, Zari, or into a recording.

FAQ

How many days before an interview should I start preparing?

Ideally 7–14 days for a senior role. For an initial screen, 2–3 days of targeted prep is enough. For a full loop or assessment centre, 2 weeks gives you enough time to complete company research, prepare 8–10 behavioral stories, practise technical questions (if applicable), and run mock interview sessions. Cramming the night before is the most common interview mistake.

What's the most important thing to research before an interview?

The company's current strategic priorities and how your target role connects to them. Most candidates research what the company does but not where it's going. Find a recent earnings call, a founder interview, or a recent product announcement and understand what the company is trying to achieve in the next 12–18 months. Then frame your answers as someone who helps achieve that mission.

How many behavioral stories do I need?

8–10 versatile stories is enough to cover all major competency areas. Each story should cover multiple frameworks: a good 'conflict' story can also serve as a 'leadership' or 'decision-making' story. Tag each story against the frameworks it demonstrates, and practise adapting them to different question formats. Don't memorise word-for-word — know the arc.

What should I do the night before an interview?

Light review, not cramming. Re-read your 5 strongest behavioral stories. Skim the company's LinkedIn page for recent news. Confirm logistics: time zone, dial-in link, recruiter contact. Lay out your clothes or test your tech. Sleep 7–8 hours. The night before is not the time to learn new material — it's the time to let what you know settle.

Reading is prep. Practicing is readiness.

Zari runs full mock interview simulations — behavioral, technical, and panel formats — with STAR scoring and specific language feedback. Practice until your answers feel automatic.
