Start with the decision
A useful place to start is Wells Fargo's New York Commercial Banking Summer Internship, requisition R-555736. Its description combines client research and financial analysis with work alongside relationship managers, product specialists and credit underwriters. That tells you more about the assignment than a broad promise to work in finance.

A concrete Summer 2027 application to inspect
The reviewed Wells Fargo posting describes a ten-week program in June–August 2027, with exact dates not yet stated. Its desired candidate profile includes bachelor's students graduating December 2027–June 2028, with all majors welcome. The listed required experience can be demonstrated through a combination that includes education.
The New York-specific narrative states $43.27 an hour, while the general pay field displays $37.50–$51.92. Keep both statements visible and confirm the applicable offer rate rather than choosing the largest number. The posting lists September 30, 2026 as its end date but warns it may be removed earlier. It also states a restriction on needing employer visa sponsorship now or in the future. These terms belong to this requisition, not every commercial-banking program.
This is a dated application example, not a guarantee that the form remains open when you read it. Use the official page for the current state.

Understand the three working relationships
For preparation, separate the questions asked by the client relationship, credit and product sides of a banking team. Their responsibilities interact, but each gives you a different way to read a role.
Client relationship: What does the business need, what has changed and which conversations should the team have? Preparing a meeting may require understanding the customer's business model, recent performance and funding plans.
Credit analysis: What supports repayment, which assumptions could fail and what information is missing? A profitable company can still face a cash shortfall if customers pay slowly or a large obligation arrives before receipts.
Product collaboration: Which available service might address the identified need, and what terms or specialist review are required? An intern should understand the question and support the process, not assume authority to approve a product or credit decision.
This framework follows the relationships named in the employer example, but the specific division of responsibilities varies. Ask which team would employ you and which deliverable a manager would expect from you.

How this differs from investment banking
A useful recruiting distinction is the decision being supported. In an acquisition-advisory discussion, you might investigate how a transaction could be structured and valued. In a commercial-banking discussion, you might investigate how a business funds operations and whether it can meet obligations under plausible conditions. These are preparation lenses, not a claim that banking divisions have identical boundaries at every firm.
Do not say you want commercial banking only because you heard it offers better hours. Actual hours depend on the employer, role and period, and the posting is the right starting point. More importantly, that answer says nothing about why you would enjoy the work.
Instead, explain a business question you find interesting. For example: why can a growing distributor be short of cash even while reporting a profit? You can reason about inventory, collection timing and supplier payments without pretending to have made a real credit decision.
Read the borrower before memorizing ratios
Choose a public company's annual report or an authorized course case. Begin with how the business earns money, who pays it, what it must spend before collecting and which obligations are fixed.
Then connect the financial statements. Rising sales may require more inventory or receivables. Debt-service capacity cannot be inferred from revenue growth alone. A large cash balance might be needed for operating commitments rather than freely available for repayment.
The useful output is a short business note with three parts: operating model, financing question and evidence still needed. You do not need a complex lending model for your first internship application. You need to be able to explain which numbers you trust, which are forecasts and how a change in one assumption affects the rest.
When discussing ratios, define both sides. Do not use cash flow, EBITDA and cash balance as interchangeable terms. An accurate explanation of one ratio is better than a list of ten you cannot connect to the business.
Show a service mindset without becoming vague
The role can require explaining information and responding reliably, not just calculating. Use a real example where you had to clarify what someone needed, organize incomplete material or communicate a delay before it became a problem.
A campus job, volunteer role or group project can supply that evidence. Explain your individual actions. “Coordinated a five-person project's submissions and resolved conflicting figures before the final presentation” is more useful than “worked well in a team.”
For analytical evidence, describe a specific reconciliation, research memo or model. Avoid dressing ordinary work in banking language you do not understand. You can be a strong student applicant without claiming transaction experience.
Prepare a defensible answer to “Why this bank?”
Look for an answer tied to the advertised business rather than an award or reputation list. The Wells Fargo example identifies a specific office and says interns learn their business placement before the program starts. A reasonable follow-up is how those placements are determined and what preparation is useful for the available teams.
For another bank, read its own program. Bank of America's student directory separates career areas and routes to specific programs; do not transfer the Wells Fargo deadline, pay or candidate window to those listings.
Compare the customer segment, office, training described and assignment structure. Your answer should demonstrate that you know what you applied for. If you cannot identify the difference between two banks' programs, research the actual roles before writing another generic cover letter.
Application details that deserve a second look
Read the qualifications in their original categories. A desired graduation window, a mandatory authorization condition and an example of relevant experience are different statements. Record them accurately and ask about an ambiguity rather than changing the heading in your notes.
Keep the requisition number, official link, submission date and any requested assessment separate. A completed application does not imply that the bank has reviewed it, and an invitation to an assessment does not mean an offer is likely.
Complete any assessment under the employer's rules. Use preparation materials to learn concepts beforehand, not to outsource a live test or misrepresent your experience.
When a posting has both a stated end date and an early-removal warning, treat the published date as a limit, not a reason to wait. Submit once your materials are accurate and ready.
What a strong initial shortlist looks like
Aim for a set of roles where you can answer four questions: which customers the team serves, what analytical work you might support, why your academic timeline fits and how you could attend the worksite.
Then prepare one business note and two experience examples. One should demonstrate analytical care; the other should demonstrate dependable communication. The objective is not to imitate an experienced banker. It is to show that you can learn the work, ask useful questions and make your analysis easy to review.
