- Competitions: Participate in data science competitions. Platforms like Kaggle provide an opportunity to experience a real-life situation competitively. Mention your participation or ranking on your resume.
- Resume Tailoring: Tailor your resume for data science. Emphasise your coursework, projects, and certifications. Use action verbs and ideally quantify your results. For example, “Analysed datasets of over 1 million records to find insights improving business decisions.”
- Networking: Get to know people and enrol in data science societies or groups on LinkedIn. Sometimes the first job offer may depend more on a network than on skills.
