What exactly did you do in your internship?

Separate what you observed from what you actually did yourself.

Model answer.

What the interviewer wants. Many resumes describe internships vaguely or overstate them. The interviewer wants to know what you actually did, what you learned, and whether you can explain it technically.

Structure

1. Where and how long: organisation, department, duration.
2. What you did yourself: tasks, tools, deliverables.
3. What you observed: processes or equipment you saw but did not handle. It is fine to say so.
4. What you learned: one technical and one professional lesson.

Sample answer (replace with your real internship details)
"I did a [duration] internship in the [department] of [organisation].

Most of the first week was safety induction and plant orientation. After that, I was attached to [team]. My main task was [specific task, e.g. collecting daily feeder load readings and preparing a comparison with transformer ratings in Excel]. I also [second task, if any].

I also observed [e.g. relay testing and a transformer oil sample test], though I didn't perform those myself.

Technically, I learned [e.g. how protection relays are coordinated in a real substation, which I had only seen in theory]. Professionally, I learned [e.g. how important documentation and permits are before any work on live equipment]."

Being honest about short or observational internships. Many internships, especially in PSUs and plants, are mostly observational because of safety rules. That is normal. Saying so clearly is better than claiming you "designed" or "commissioned" something. Interviewers know what interns are allowed to do.

Preparation

• Revise the theory behind what you saw (for example, the working of the equipment).
• Keep your internship report and certificate handy, and make sure the dates match your resume.

Common mistakes

• Using big words like "managed" or "designed" for tasks you only assisted with.
• Being unable to explain basic questions about the equipment you mention.

Likely follow-up. "What was one problem you saw there, and how would you solve it?" Prepare one observation and a sensible suggestion.
