During my first three years of college I landed three internships. This is how I prepared for every single one of them.

I used to prepare for interviews the way most students do. Read the company website. Skim the job description. Prepare a few generic answers about my strengths and weaknesses. Hope for the best.2

The results were predictable. I could answer the questions but I never said anything that made the interviewer lean forward. I was giving the same answers they had heard fifty times that week.

Then I started using ChatGPT to prepare and everything changed. Not because it wrote my answers for me, but because it helped me walk into every interview knowing more about the company, the industry, and the role than most candidates who had been preparing for weeks. This post covers exactly how I do it.

Most students prepare for generic interview questions. "Tell me about yourself." "What is your greatest weakness." These matter but they are not what separates candidates at competitive internships and graduate roles.

The first thing I do is ask ChatGPT for the specific questions that come up in interviews for the exact field and company type I am applying to.

The prompt I use:

"I am interviewing for an internship at a [type of company] in the [field] industry. What are the most common interview questions companies in this field ask, including both behavioral and technical questions? Give me the ten most important ones and explain briefly why each one gets asked."

What comes back is a focused list of questions tailored to that specific context. Not generic interview prep. Actual questions that reflect how that industry thinks and what they are really testing for when they ask each one.

Practice every question on that list before your interview. You will walk in having already thought through scenarios that most candidates encounter for the first time in the room.

This is the part of my preparation that made the biggest difference.

I would draft a rough answer to each interview question based on my actual experiences. Then I would paste it into ChatGPT and use this prompt:

"Here is my rough answer to this interview question: [paste your answer]. Please restructure this into a clear, compelling response that highlights the key points. Then give me a three point summary of the main things I need to remember so I can deliver this naturally without memorizing the entire script word for word."

What comes back is a polished version of your answer with a short three point summary at the bottom. You practice until the three points are in your head. In the interview you recall the points and build your answer naturally around them. It sounds genuine because it is genuine. It is your experience, just structured better.

This approach works significantly better than memorizing a full scripted answer which always sounds robotic under pressure.

This is where most candidates stop and where you can immediately stand out.

Reading a company's About page tells you what they want you to know. Understanding the industry they operate in tells the interviewer that you think like someone who is already in the field.

I use two prompts for this. The first is for industry level research:

"Give me a comprehensive overview of the [industry] industry in 2026. Include the current market size, the CAGR, the key trends shaping the industry right now, the major competitors and what they have been doing recently, and the biggest challenges companies in this space are facing."

The second is for company specific research:

"I have an interview at [company name]. They operate in [industry]. Tell me everything I should know about this company before my interview. Include their business model, recent news, key products or services, their main competitors, and any recent strategic moves or announcements."

In my own interviews I have used the industry overview prompt to find specific data points like the CAGR of the market and what key competitors had done in the past year. When I brought those numbers up naturally in conversation, the interviewers visibly took notice. Most candidates show up knowing the company. Almost none show up knowing the industry.

That gap is where you win.

Once you have your questions and your answers prepared, use ChatGPT to run a full mock interview before the real one.

Use this prompt to set it up:

"I want to do a mock interview for a [role] position at a [type of company] in the [industry] field. You are the interviewer. Ask me one question at a time, wait for my answer, then give me brief feedback on what was strong and what I should improve before asking the next question. Start with the first question now."

Run through the full interview at least once. The feedback after each answer tells you specifically what is landing and what needs more work. Doing this the night before an interview is the closest thing to a cheat code for interview performance that I have found.

Every interview ends with "do you have any questions for us?" Most candidates ask something generic. A few ask something that makes the interviewer think.

Use this prompt to prepare:

"I am interviewing for a [role] at [company] in the [industry] industry. Generate five thoughtful questions I could ask my interviewer that would demonstrate genuine curiosity about the role, the company's direction, and the industry. Avoid generic questions that every candidate asks."

Pick two or three of the best ones and make them yours. Add a specific detail from your research to one of them and it becomes a question that signals serious preparation.

If you have an interview coming up in the next two weeks, open ChatGPT tonight and run the industry research prompt for the company you are interviewing at. Spend thirty minutes reading what comes back and identifying two or three specific data points you can bring up naturally in conversation.

That one step alone will put you ahead of most candidates walking into the same room.
