Having an effective and impressive resume is important if you want to land a data science role. However, many candidates make mistakes that prevent their resume from standing out and landing interview calls.

This guide will walk you through five common resume mistakes that aspiring data scientists often make. No worries, we’ll also go over actionable tips on how to avoid them.

Let’s get started.

1. Not Showcasing Practical and Impressive Projects

A major pitfall in many data science resumes is the absence of useful projects. While having certifications and degrees is important, hiring managers want to see how you apply your skills to real-world problems.

Why this matters

Without strong projects, recruiters are often left guessing if you can apply theoretical knowledge to real problems.
Projects are the best way to show the impact of your skills, such as how you’ve improved business processes or answered business questions.

How to avoid

Include at least 3-5 diverse projects on your resume. Work with real-world datasets. Focus on building and deploying machine learning models. And link to the project in your portfolio.
Be sure to highlight the tools you used (Python, R, and SQL), the libraries you’ve used, the size of the dataset, and specific results or business impacts.
Use metrics wherever possible. For example, “Built a predictive model that reduced customer churn by 15% using random forest algorithms on a dataset of 100K customer records.”

If you’re a beginner with no previous data science experience, start by contributing to open-source projects, participating in Kaggle competitions, and personal projects on weekends.

2. Adding Too Many Buzzwords Instead of Demonstrating Skills

A resume packed with data science jargon like “machine learning,” “deep learning,” or “big data” might seem impressive. But if it’s just a list of buzzwords without evidence, it can backfire.

Why this matters

Recruiters and hiring managers look for evidence of your skills, not just their mention as keywords.
Loading your skills section with all the tools and libraries you’re familiar with can work against you if you don’t have the experience or projects to speak of.

How to avoid

Instead of listing terms like “data cleaning” or “predictive modeling” generically, describe how you applied those skills in a specific project.
For example, instead of writing “proficient in machine learning,” you can say, “Developed a machine learning pipeline that identified high-value customers, leading to a 20% increase in sales conversion.”

In short, you should focus on tangible results and outcomes tied to your skill set rather than purely listing technical terms.

3. Not Customizing Your Resume Enough

One size does not fit all when it comes to data science resumes. Sending the same resume for every position you apply to can significantly decrease your chances of landing an interview.

Why this matters

Data science is a broad field, and each company will have different expectations and requirements depending on the industry.
If your resume is too generic, recruiters can tell that you didn’t take the time to understand their specific needs. A resume submitted to an ML engineer role at a medical imaging startup should not be identical to the one you submit for a data scientist role at a fintech company.

How to avoid

Customize your resume for each job by tailoring your projects, skills, and keywords to match the job description. But be honest and include only projects and skills that you’ve worked on.
Be sure to highlight experiences that directly align with the company’s industry. For example, for a finance-focused role, emphasize projects related to financial data or risk analysis.

This is possible only when you diversify and work on a range of projects depending on which industry you’d like to work as a data scientist in.

4. Not Quantifying Impact and Achievements

A data scientist’s job revolves around numbers and data. So failing to quantify achievements on your resume is a missed opportunity 🙂. Numbers add credibility to your claims and demonstrate the real impact of your work.

Why this matters

Vague descriptions like “improved data accuracy” or “developed predictive models” don’t give the recruiter any sense of scale or success.
Quantifiable metrics are easy to digest and help make your contributions stand out.

How to avoid

Include metrics for every relevant project or job experience. Focus on things like accuracy improvements, cost savings, time reductions, or business impacts.
If you can’t share exact numbers, use approximations such as “approximately 10% improvement” or “reduced processing time by nearly half.”

This is super important; because even if you’ve worked on complex and interesting projects, you should be able to talk of their impact.

5. Neglecting Soft Skills and Business Acumen

While data science is highly technical, companies are increasingly seeking candidates who can also demonstrate soft skills such as communication, teamwork, and most importantly, a good understanding of how businesses work.

Although soft skills mostly fall into the “show don’t tell” category. Focusing only on technical expertise and ignoring these areas can be detrimental.

Why this matters

As a data scientist, you should be able to communicate complex findings to non-technical stakeholders.
Companies want data scientists who can make data-driven decisions that align with business goals and solve business problems.

How to avoid

If needed, dedicate a section of your resume to soft skills. Mention any instances where you’ve presented the project to the team or collaborated across teams.
When possible, link your technical achievements to business outcomes. This shows you understand the broader impact of your work.

Oh, and no worries. There’s a lot of opportunity to demonstrate soft skills during later stages of the interview process. 🙂

Conclusion

Building a strong data science resume is more than just listing technical skills and describing projects. As discussed, it requires showcasing real-world impact of your projects, adding metrics where possible, and customizing your experience to match job roles.

By avoiding these common mistakes and following the outlined tips, you’ll be able to create a resume that stands out in the data science job market.
