How to explain your job or project simply

“So what do you actually do?”

You’ve heard it at family weddings, from new colleagues, from interviewers. And many of us answer with a job title and a cloud of jargon: “I’m an associate in the data engineering team, working on ETL pipelines for a BFSI client.” The other person nods politely and changes the subject.

Explaining your work simply is one of the most useful skills you can build. It helps in interviews, in client meetings, in performance reviews, and yes, with relatives. It is also a sign that you really understand what you do.

Why it’s harder than it sounds

When you work on something every day, you forget what it looks like from outside. The acronyms, tools and team names become normal to you. You stop noticing that other people don’t know them.

This is sometimes called the “curse of knowledge”: once you know something, it’s hard to imagine not knowing it. The fix is a simple method that forces you to start from the listener’s side.

The method: Who, Problem, What you do, Why it matters

1. Who it’s for

Start with the people who benefit, in plain words. Not your client’s name or industry code. People.

• “Banks” instead of “BFSI clients”.
• “Small shop owners” instead of “MSME merchants”.
• “People who order food online” instead of “end users”.

2. The problem

What problem do they have? Say it in one sentence a twelve-year-old could follow.

• “Banks need to know quickly if a transaction might be fraud.”
• “Shop owners spend hours every week doing their accounts by hand.”

3. What you do

Now say your part, in plain verbs. Build, fix, check, design, explain, sell. Not “leverage”, “facilitate” or “drive”.

• “I build the systems that move transaction data from the bank’s branches to the team that checks for fraud.”
• “I test the app before every release, to catch bugs before shop owners see them.”

4. Why it matters

Finish with the result. What gets better because of your work?

• “If the data is late, fraud gets through. My job is to make sure it arrives within a minute.”
• “Every bug I catch is one less angry phone call to our support team.”

Before and after

Before:

“I work in the data engineering team on ETL pipelines for a BFSI client, mainly using Spark and Airflow on AWS.”

After:

“I work for a bank. When someone makes a payment, the bank needs to check quickly whether it might be fraud. I build the systems that get that payment data to the fraud team within a minute. If it’s late, fraud gets through.”

Same job. The second one makes sense to anyone, and it makes you sound more senior, not less.

Before (a final-year project):

“We implemented a CNN-based classification model with transfer learning on a custom dataset for agricultural applications.”

After:

“Farmers often can’t tell which disease is affecting their crop until it’s too late. We built an app where they take a photo of a leaf, and it tells them the most likely disease. It got about 85 percent right on our test photos.”

Adjusting for your listener

The method stays the same; the level of detail changes.

• A relative or friend: Stop after “Why it matters”. That’s enough.
• An HR interviewer: Add one result or number.
• A technical interviewer: Start simple, then add one layer of detail: “We used Spark because the volume is around ten million transactions a day.” Let them ask for more.
• A client: Focus on “Why it matters” for them specifically.

A good test: explain it simply first, then ask “Do you want the technical version?” Most people will say no. The ones who say yes will appreciate that you could do both.

Common mistakes

• Starting with your title. “I’m a Senior Associate…” tells people your rank, not your work.
• Starting with tools. “I use Python and SQL…” Tools are how, not what.
• Using company or team names. “I’m in the Phoenix pod under CXO.” Nobody outside knows what that means.
• Going too long. The simple version should take 20–30 seconds.
• Being vague to sound important. “I drive strategic initiatives.” What do you actually do on a Tuesday?

Practise it out loud

Write your job or project using the four steps. Then say it out loud to three people with different backgrounds, say a family member, a friend from another field, and a colleague. Watch their faces. Where they look confused, simplify.

Then record your 30-second version and listen back. If you hear jargon, cut it. Repeat until it sounds like something you’d say to a friend.

This is exactly the skill behind interview questions like “Tell me about yourself” and “Walk me through your resume”. Get it right once and you’ll use it for years.
