Field Notes / Interview Prep
How to Prepare for a Job Interview, Ranked by What Decides It
From the hiring chair, you see it in two questions. Most candidates prepare the lowest-value thing first, because it feels like work.
I sat on hiring panels for nearly ten years. You learn to spot the shape of someone's preparation inside two questions. Not whether they prepared. What they prepared.
The common failure is not laziness. It is a candidate who worked hard on the wrong layer.
Research feels like preparation
Reading about a company is comfortable. It is finite, it is quiet, and you finish with pages of notes. So people do it first, then run out of evening.
Then the interview starts and nobody asks about the funding round. They ask you to tell them about a time. And the notes do not help, because the thing being tested is not what you know about them. It is what you did, and whether you can say it.
What decides it
Two things carry most of the weight, and both live in your own history rather than theirs.
- Your stories, said out loud. Eight achievements, each written as a situation, an action, and a result. Then spoken. Not reviewed in your head. Spoken, so the sentences exist before the room asks for them. This is the single highest-return hour of preparation you will spend.
- Why this role. One honest answer to why this job, at this company, now. Panels ask it constantly and hear filler almost every time. A real answer separates you from the field faster than any fact you memorized.
What earns its place next
Below those two sit the layers worth real time.
- Your resume, defensible line by line. Every claim on the page is fair game. Read your own resume as an interviewer would and mark anything you would probe. A number you cannot explain is worse than no number.
- Questions you ask them. Not to seem engaged. To learn whether you want the job. Ask what success looks like at six months. Ask what the last person in the role found hard. The answers tell you more than the posting.
- The technical themes. Read the posting for what it keeps circling back to. Prepare depth on those. Skip broad revision of everything you have ever touched.
What matters least
Company facts sit at the bottom. Know what the company does, know its main products, know roughly how it makes money. Fifteen minutes covers it. Beyond that, extra research pays almost nothing, because a panel scores your judgment rather than your recall.
The trap is that this layer feels the most productive while you are doing it.
A week that works
Turn the stack into a schedule and the effort lands in the right place.
- A week out. Write the eight stories. Say each one out loud once.
- Midweek. Drill the weak ones. Fix your weakness answer while you are there, since it comes up more than any other single question.
- Two days out. Reread your resume as an interviewer. Draft the questions you will ask.
- The day before. Fifteen minutes on the company. Then stop.
- Ten minutes before. Warm up. Say your opener, run one story, close the notes.
Preparation is not one pile of work. It is a ranked list, and the order matters more than the hours. Start with your own stories. Finish with their funding round, if there is time left.
