How to Research a Company Before an Interview: 30-Minute Plan

Last updated: 21 September 2026 · By the Asuraa Team

How do you research a company before an interview?

Work through a short checklist in a fixed order, and finish by turning what you found into questions and talking points. Thirty focused minutes is usually enough for a first-round interview.

The checklist below covers the official site, products, news, people, reviews and, for India, a legal existence check. A time-boxed plan follows it.

What should you check first?

Start with the source the company controls. Purdue Global's company research guide begins with the company website, including the "About Us" and "Careers" pages, to understand the mission and values.

Read the job posting again alongside it. Note the skills it asks for, the team it mentions and any words that repeat, because those are likely to come up in the interview.

How do you learn what the company actually does?

Look at its products or services and who buys them. A useful test is to explain the business in two sentences to a friend, including who the customers are and how the company earns money.

If the company is small or new, its product pages, blog and social profiles usually show more than its brochure text. Purdue Global also suggests looking at social media to see how a company presents itself.

Which news and leadership details are worth checking?

Search the company name in the news tab for recent launches, funding, layoffs, awards or problems. Purdue Global suggests using Google Search and the news tab to find recent developments or difficulties.

Then look up the leaders and your interviewer on LinkedIn. Note their backgrounds and any common ground, such as a college, a previous employer or a shared interest.

Can you trust employee reviews?

Use them as one signal, not a verdict. Ohio State's engineering career services lists Glassdoor as a place to find company descriptions, employee reviews and past interview questions.

Purdue Global adds a caveat: employees who are unhappy tend to post more often than those who are satisfied. Look for patterns repeated by several people over time, and treat a single dramatic review with caution.

How do you check that an Indian company is registered?

Search for it in the Ministry of Corporate Affairs (MCA) company master data. Tally Solutions' guide to searching a company by CIN explains the steps: open mca.gov.in, go to MCA Services, choose View Company/LLP Master Data, enter the 21-digit CIN and complete the captcha.

The result shows details such as the company name and status, date of incorporation, registered office address and director details. Compare these with what the recruiter and the website say, and be cautious if names, addresses or status do not match.

This check only covers registered companies and LLPs. If you cannot find a CIN on the website or offer letter, ask the recruiter for it. For a fuller checklist, read our guide on how to verify a company before applying in India.

What is a 30-minute plan you can follow?

Use a timer so that research does not turn into scrolling. This is one way to split the time.

If you have more time, talk to someone who works there or a mentor from the same field. Purdue Global also lists tapping your network as a step.

What questions should you ask the interviewer?

Prepare three to five, and pick ones that show you did your research. Ohio State's guide suggests examples such as how the team builds relationships, what the role contributes to team goals, what challenges the team has faced recently and what development opportunities exist.

HBR advises choosing questions relevant to you and the job in advance and writing them down. If time is short, pick the two or three that matter most. It adds that asking questions is both a chance to keep proving yourself and a way to learn whether the job is right for you, as HBR's list of 38 questions explains.

How do you use your research in the interview?

Weave two or three facts into your answers and do not recite them. When asked why you want the job, connect one product or recent development to a skill you have used, and give a short example.

If your research turned up something concerning, such as mismatched registration details or repeated complaints about unpaid salaries, raise it politely or take more time before accepting. Ohio State's guide also stresses that research is about judging your own fit, not only about showing knowledge.

What do most guides on how to research a company before an interview get wrong?

Many guides give a long list and no plan. These are the common gaps.

• They skip the time box. A list of ten places to look is not a plan, and many candidates run out of time before they write any questions.
• They treat reviews as truth. Review sites show only the people who chose to post.
• They ignore India-specific checks. A registered company can still be the wrong employer, but an unregistered one is a warning sign, and MCA master data can be searched online.
• They stop at facts. Research helps most when it turns into questions and a clear reason you fit.

FAQ

How long should I spend researching a company before an interview?

About 30 minutes is enough for a first-round interview if you follow a checklist: website, products, news, people, reviews, registration check and questions. For final rounds or roles you badly want, add time to speak with someone who works there.

Where can I find information about a company?

Start with the official website and careers page, then read recent news, LinkedIn profiles of leaders and your interviewer, and employee reviews. In India, the MCA company master data shows a registered company's status and address. Cross-check what different sources say.

How do I check if a company is registered in India?

Use the MCA website's View Company/LLP Master Data service and enter the company's 21-digit CIN. It shows details such as name, status, incorporation date, registered address and directors. Ask the recruiter for the CIN if you cannot find it.

Are Glassdoor reviews reliable?

They are one signal and not a verdict. Purdue Global notes that disgruntled employees tend to post more often than satisfied ones. Look for repeated themes across many reviews and dates, and combine them with news, the company website and people you know.

What questions should I ask at the end of an interview?

Prepare three to five that fit the role, such as how the team works, what success looks like in the first months, recent team challenges and learning opportunities. HBR suggests choosing them in advance and writing them down.

What should I do if I find red flags?

Slow down and verify further. Check that the CIN, address and names match across the MCA record, website and offer letter, and ask the recruiter to clarify. Never pay a fee or share sensitive documents until you are confident the offer is genuine.

Final thoughts

Good company research is short, structured and useful. Spend thirty minutes on the checklist, write your questions and keep the legal and safety checks in view.
