Ms Siew Ling Tan

Head of Analytics

Harbour Mart Group

Subject: Application for Data Analyst

Dear Ms Tan,

Six hours of copying became one hour at Lion City Retail Group once I automated the weekly sales report in SQL and Python. I am applying to be the Data Analyst at Harbour Mart Group so your store and finance teams get that time back too.

The same job taught me that a report only helps when people open it. I built a weekly Power BI sales dashboard for 24 outlets, and area managers now open it for their Monday review. First I had to clean and merge data from three systems, which brought mismatched product codes down from about 300 to under 20. I also found 60 slow-moving products holding a fifth of stock value, and the buying team used my list to plan markdowns.

Harbour Mart's move from spreadsheets to one Power BI workspace is the part of this role I want most, because I have already lived through a smaller version with three systems that disagreed. The advert also asks me to present findings to non-technical managers. In a personal project on store footfall, I compared door counts with sales for 24 stores and wrote a one-page summary recommending new opening hours for six of them. As an intern at Marina Bay Research, I drew the charts for a loyalty study based on survey data from 1,200 customers.

A sample task on a messy extract from two of your systems would show how I work better than an interview answer can. Before that, I could send the footfall summary with the store names removed.

Kind regards,

Rahul Menon

A made-up letter. The person, the employers and every number are invented, and any resemblance to a real one is chance. Sending it by email? Put the subject line in the email’s subject box, add your name to it, and attach the letter as a PDF.

Paragraph by paragraph

  1. The opening

    Starts: “Six hours of copying became one hour…”

    Opens on time saved, a result any manager understands, and names the role and company in the next sentence.

  2. Your strongest evidence

    Starts: “The same job taught me that a…”

    Each result names who used it, which shows the analysis changed a decision rather than sitting in a folder.

  3. Why this employer

    Starts: “Harbour Mart's move from spreadsheets to one…”

    Gives a real reason for this employer, its reporting move, and says plainly that the footfall study was a personal project so the reader is not misled.

  4. The close

    Starts: “A sample task on a messy extract…”

    Offers a practical test and a work sample, both suited to a junior analyst with two years of experience.

Why this letter works

  • Hours saved and product codes cleaned are results a manager can check.
  • The reason for applying is the employer's own project, not a compliment about its stores.
  • The personal project is labeled as one, which keeps a short career honest.
  • The close invites a practical test, which suits analysts who are often hired on a task.

How to write your own data analyst cover letter

  1. Lead with hours saved by automation; it is the fastest result for a hiring manager to grasp.
  2. Say how often managers open your dashboard and in which meeting, not only that you built it.
  3. Label a personal or study project as one, so nobody mistakes it for paid work.
  4. Offer to take a short data task on a messy extract; many analytics teams hire that way.
  5. Name the reporting tool the employer is moving to if you already use it.

Common questions

Is a data internship worth a sentence once you have a full-time analyst job?

Yes, when it shows a skill the advert names that your current job does not, such as preparing survey data or charting for a senior manager.

How do I describe a dashboard without screenshots?

Say who opens it, how often and what decision it supports. That tells the reader more than a picture of the charts.

Can a personal project count as experience?

It can show a skill, as long as you call it a personal project and state the question it answered and the change you suggested.
