Use the job's output to choose a function
Supply-chain work spans purchasing, inventory, transportation and warehousing. For an internship, narrow that down to the assignment you would support. Use this table to decide what to ask about and which example from your coursework or employment to discuss.
| Search terms | Question the work addresses | A sample worth preparing |
|---|---|---|
| Demand planning; inventory | What is likely to be needed, and when? | A forecast with its time period and a comparison against actual demand |
| Purchasing; procurement; sourcing | Which offer meets cost and delivery needs? | A supplier comparison with freight and missing terms included |
| Logistics; transportation; distribution | Which orders need action? | A delivery report with exceptions and a named next step |
| Manufacturing; operations | What prevents the process from meeting its target? | A process map with a measured or explicitly fictional bottleneck |

The higher unit price can be the cheaper offer
Here is a fictional purchase of 1,000 units. Compare the same quantity delivered to the same destination before choosing a supplier.
| Cost item | Supplier A | Supplier B |
|---|---|---|
| Unit price | $4.00 | $4.20 |
| Cost of 1,000 units | $4,000 | $4,200 |
| Freight | $300 | $50 |
| Total | $4,300 | $4,250 |
What the comparison supports
On time is not the same as complete
Suppose a fictional order is for 100 units and 60 arrive by the promised date. It passes an arrival-date check but still has a 40-unit shortfall. A report that calls it successful without defining success could send the team in the wrong direction.
Include promised date, actual delivery, ordered quantity, received quantity and the next action in an exception report. The delivery exercise below shows a second problem: missing delivery dates. It calculates the rate among known outcomes separately from the share of all orders confirmed on time.
The next action should identify what to resolve, such as checking a missing delivery confirmation or asking the order owner about the remaining quantity. A red cell alone does not tell anyone what to do.
Two employer routes with different schedules
GE Aerospace's U.S. program describes paid, 10–12-week opportunities, including materials, planning, logistics and sourcing. Caterpillar's separate paid part-time student program includes supply chain, logistics and purchasing and requires a workable commute to the facility.
Use these as routes to current requisitions, not interchangeable offers. A full-time summer placement and a local part-time role solve different scheduling needs. Check the relevant academic conditions, site and hours before preparing an application.
Show one operational problem you understood
A stock-count discrepancy, a delayed event shipment or a course purchasing case can provide relevant application evidence. Explain what you checked and what decision followed. Do not rename every spreadsheet a supply-chain optimization project.
Before accepting, get the facility address and required shift or meeting hours. Ask who reviews your work and who can authorize changes to orders or suppliers. A good internship lets you understand a decision without assuming authority you have not been given.
