Generic interview preparation doesn’t cut it anymore.
I get it. It’s easy. It’s what you know.
It’s how I used to prep for interviews—and for a long time, these are tactics I recommended to my clients, e.g.
-
Googling sample interview questions
-
Practicing answers in your head
-
Mock interviews with friends
But the tooling to help you nail your interviews have up-leveled 10x in the last 3 months (and they’re free). If you’re not taking advantage, you’re literally leaving money on the table.
You can create a full on AI interview coach with full context on yourself and the roles and companies you’re apply for, in a few minutes. And that coach is there with you 24-7, never getting tired and always ready to tweak your approach.
Let’s jump into it.
🤖 How to build your personal interview coach
Start by creating a dedicated AI project in Claude or ChatGPT. Name it “[Company] Interview Prep.”
✍️ Then give your coach a clear persona with this system prompt:
“You are my interview coach for [Company] [Role]. Challenge my thinking, point out gaps in my answers, and help me structure responses using frameworks. Be direct about weaknesses. I need to be ready, not comfortable.”
👉 How to set up your system prompt:
-
ChatGPT: Create a project (sidebar) → Add custom instructions or paste your system prompt in the project settings.
-
Claude: Create a project (sidebar) → Click “Set custom instructions” → Paste your system prompt in the project knowledge section.
The secret sauce is feeding it all the context it could possibly use. I’m talking about:
-
Your resume
-
Job descriptions
-
Company 10-K filings
-
Research dossiers
-
Recent earnings calls
-
Product screenshots
-
Interview questions (pull from Exponent or Glassdoor)
📝 Put it to work at every phase
Once your AI interview coach is locked in, put it to work every chance you can:
Before applying:
“Review this job description. What skills should I emphasize?”
Before interviews:
“Give me 10 likely questions for a [role] at [company].”
”Role play an interview with me. Ask me 1 question at a time. When we’re done, give me detailed feedback on my answers.”
After each round:
“Here’s how I answered X. How could I improve?”
The AI remembers everything. It knows your background, the company’s priorities, and can spot patterns in your weak answers that you’d miss.
