How to research a company before an interview

The four things actually worth knowing

Research isn't about memorising the “About” page. It's about four things that change how you show up:

• How they make money. The product, who pays for it, and the business model. This is the one that tells you whether you actually want the job — and it's the backbone of a real “why this company” answer.
• How they work. Culture, pace, autonomy, remote policy, and what they visibly value. This tells you which of your stories to lead with, and whether you'd be happy there.
• The last 90 days. Funding, a launch, a reorg, layoffs, a new exec. Recent change is what makes your questions sound current instead of generic, and it often signals what the team is under pressure to do.
• The interview style. The loop shape and what each round tests for your role — covered for 28 roles in our 2026 Tech Interview Report and each role guide.

Where to look — and how much to trust it

Each source answers a different question, and some need a pinch of salt:

• The company's site and recent news — the business, the direction, what shipped. The most reliable, least filtered signal.
• The job description — what they're prioritising right now, often more honest than the marketing. Read it twice.
• levels.fyi — compensation reality by level, so you walk in with a number.
• Glassdoor and current employees — culture and interview experience, but weighted carefully. Reviews skew to the extremes, so treat strong claims as leads to verify, not facts.

The trick is triangulation. Anything that shows up across the site, the recent news, and a couple of employees is probably true. A single furious Glassdoor review is a data point, not a verdict.

Turn research into interview material

Facts you can't use are trivia. Convert what you find into three things that actually score:

1. A specific “why this company.” Tie one true thing about them to one true thing about you. Specific beats admiring every time.
2. Calibrated stories. If they value speed and scrappiness, lead with the time you shipped fast; if they value rigour, lead with the careful one. Same career, different emphasis.
3. Questions that show you did the work. Ask about the thing that changed last quarter, the trade-off behind a recent launch, how the team is set up for what's next. The questions you ask are part of how you're graded — see what gets you the offer.

The fast way: a company snapshot

You can do this by hand in twenty minutes, and it's worth knowing how. Calibrd just does the first pass for you. Paste a real job description and its Company snapshot returns a short brief on three things — the business (market and scale), the culture (how they work), and the compensation philosophy — drawn from roughly the last 90 days, with a confidence flag so you know how much to lean on it. It even flags that culture claims are hard to verify and worth checking against Glassdoor, because the honest version of research tells you where it's soft.

It's a first pass, not the last word — you still sharpen the “why this company” and decide which stories to lead with. But it gets you from a blank page to something to react to, fast, and it sits next to the predicted questions and comp benchmark for the same role.

So what do you actually do

1. Learn how they make money first — it decides whether you even want this.
2. Read the JD twice, skim the site and the last few months of news, and check levels.fyi for comp.
3. Read culture sources, but verify strong claims instead of taking them at face value.
4. Convert it all into a specific “why this company,” calibrated stories, and two or three sharp questions to ask back.
