The question tell me what you know about us shows up in some form in almost every interview. Most candidates give a generic answer pulled from the company's About page. The candidates who get offers give specific answers that show they understand the business, the product, and the challenges the team is actually working through.
The difference is not intelligence. It is preparation. And preparation is something you can control completely.
What to Research
Start with the product. Use it if you can. Sign up for a free trial. Download the app. Go through the core user flow and pay attention to what works well and what does not. Interviewers notice when you have actually used what they built. It comes through in how you talk about it.
Read recent news about the company. Search the company name in Google News and filter to the last three to six months. Look for funding announcements, product launches, leadership changes, and any public statements from the founders or executives. These give you real material to reference in the conversation that signals you are paying attention to more than their Wikipedia page.
Look at their engineering blog if they have one. Many tech companies publish technical posts about the problems they are solving, the architecture decisions they have made, and the challenges they are working through. Reading two or three of these gives you more genuine insight into the work than anything else you will find publicly.
Research the People You Are Meeting With
If you know who is interviewing you, spend ten minutes on their LinkedIn and look for anything they have written, presented, or worked on publicly. You do not need to memorize their career history. You need one or two specific things you can reference naturally in the conversation to show that this is not your first time hearing their name.
People remember when you have taken the time to learn something about them. It is one of the clearest signals you can send that you are genuinely interested in the opportunity rather than sending the same application to fifty companies.
How to Use What You Find
The goal is not to perform your research in the interview. Nobody wants to hear a recitation of their own press releases. The goal is to have the research inform your questions and your answers in ways that feel natural.
When they ask why you want to work here, your answer should reference something specific. When they ask what challenges you think the company faces, you should have a real opinion based on what you read. When you ask your questions at the end, at least one of them should come from something you found during your research.
The Questions You Ask Matter
The questions you ask at the end of an interview reveal more about you than you might expect. Generic questions like what does the day-to-day look like signal that you have not thought hard about the role. Specific questions like I noticed you recently expanded into enterprise accounts, how has that changed the engineering priorities for your team signal that you were paying attention before you walked in.
Prepare three to four questions. You will probably only get to ask two, but having extras means you can adapt based on what comes up during the conversation.
The Bottom Line
Research takes an hour. It changes the entire quality of the interview. Most candidates skip it or do the minimum. Showing up with specific knowledge about the product, the company, and the people you are meeting is one of the simplest ways to separate yourself from everyone else who is interviewing for the same role.
