How to apply Email your CV and a cover letter to
info@stackdatastrategy.com
by 30 January 2026 with the subject line: Data Science Role.
Your cover letter should include:
Why you’re applying, and how you think you can help Stack succeed.
In no more than two paragraphs, your answer to the following: How do you view the role of AI in data science and data analysis?
In no more than three paragraphs, your response to the following scenario: Pick any political party in a democratic nation, preferably one that is not currently leading in public polls. Imagine that you have been commissioned by the party to run a large sample poll of their country, with the goal of producing a one‑page briefing to direct decision making. Outline briefly (at most 1 paragraph) the challenges faced by the party, then outline (in the remaining space) how you would approach this research, which should include what you would collect in the poll, the analyses you would expect to run on the results, and how you would use those results and that analysis to advise the party.
These exercises are designed to test your own thinking and writing, so please make sure that your answers reflect original work. We understand that tools such as ChatGPT can be useful in the writing process but we encourage you to avoid submitting answers that are fully AI‑generated. Submissions that rely too heavily on LLMs/AI are often easy to recognise and will negatively affect your application.
