The Top 10 Mistakes Data Scientists Make When Job Hunting (And How To Avoid Them)


Job hunting as a data scientist can be a daunting task. With so much competition and confusing job descriptions, it’s easy to make mistakes that can cost you your dream job. Avoid these common pitfalls with some simple tips and tricks.

The Importance of a Focused Data Science Job Search

With the rise in popularity of data science over the last decade, the job market has become saturated with applicants. Companies are inundated with generic resumes from smart people who “like math and computers.” To stand out, you need a focused search based on roles that fit your unique background and interests.

Setting the Stage: Why People Make Mistakes

It’s not entirely job seekers’ fault. Job postings are often vague, requiring experience in every buzzword under the sun. And with no standardization of titles, roles vary wildly between companies. This confusion leads applicants to make preventable mistakes.

The Top 10 Mistakes

Mistake 1: Not Tailoring Your Resume to the Job Description

The Generalist Resume Problem

Don’t lazily submit the same generic resume to every opening. Study the job description and tweak your resume to fit. Highlight relevant skills and experience up top. Grab the hiring manager’s attention.

Importance of ATS (Applicant Tracking Systems)

Many companies use ATS to screen resumes. These programs scan for keywords from the job description. If your resume is tailored, you’re more likely to pass the robot test.

Mistake 2: Neglecting Your Online Presence

Clean Up Your Social Media

Like it or not, hiring managers will Google you. Delete any unprofessional posts and make sure your profiles are polished.

Start a Blog or Contribute to Open Source

Show your skills and thought leadership online. Having a professional presence can give you a big advantage.

Mistake 3: Not Practicing for Interviews

Know Common Questions and Prepare Stories

Expect behavioral questions like “Tell me about a time you overcame a challenge.” Have stories ready to highlight your skills.

Practice on Platforms Like Pramp

Hone your technical interview skills on practice sites. They connect you with peers and provide feedback.

Mistake 4: Typos and Grammatical Errors

These May Seem Like Minor Mistakes

But sloppy typos or bad grammar can immediately disqualify you. Recruiters will doubt your analytical skills if you don’t carefully proofread for errors. Read over your materials several times or have a friend review. Don’t let obvious mistakes torpedo your chances.

Mistake 5: Exaggerated or False Claims

Stretching the Truth Will Backfire

Exaggerating on your resume or in interviews will only come back to haunt you. Data science values rigorous honesty. If you fudge the facts about your skills and experience, you’ll likely fail any technical screens. Be truthful about your background and let your work speak for itself.

Mistake 6: Overusing Technical Jargon

Explain Concepts Clearly

It’s great you understand advanced techniques like Bayesian inference and ensemble modeling. But recruiters may not. Avoid esoteric vocabulary and acronyms when possible. Explain your work clearly without getting overly technical in early conversations. You can dial up the stats talk in later stage interviews.

Mistake 7: Bad Mouthing Past Employers

Stay Positive

Never trash talk or complain about previous jobs or managers. This makes you look unprofessional and negative. Keep things positive when discussing your background and focus on the valuable experience you gained.

Mistake 8: Skipping the Cover Letter

Explain Why You’re a Great Fit

Even if not required, a cover letter allows you to connect your experience directly to the role. It’s a chance to explain why you’re an ideal fit for the job. Not including one means missing a key opportunity to stand out.

Mistake 9: Waiting Too Long to Follow Up

Promptly Send Thank You Notes

After an interview, promptly send a thank you note or email within a few days. Recruiters are busy, so following up shows you’re enthusiastic about the role. If you wait weeks, they may have forgotten you.

Mistake 10: Using Silly Fonts or Colors

Keep it Professional

A data science resume should look professional and sleek. Save the Comic Sans and neon colors for another time. Stick to simple, clean fonts like Arial, Calibri or Times New Roman in black or dark blue.

Tips to Navigate the Job Search Effectively

Searching for a new job can feel overwhelming. With so many potential mistakes and no clear path, it’s easy to get lost along the way. Follow these tips to keep your search focused and dramatically increase your chances of success.

Clarify Your Goals

Before doing anything else, get very clear on what you want. Note your must-haves for roles, like salary, location, and responsibilities. Rank your priorities. This focuses your search on ideal fits. Casting too wide a net makes it hard to tailor your approach.

Optimize Your Resume Strategically

With your goals clarified, tweak your resume for each application. Emphasize different skills and experiences to fit the role. Lead with the most relevant info. You can keep a master resume with all details as your starting point.

Search Job Sites Efficiently

Big boards like Indeed are helpful to cast a wide net. But roles on niche sites like are often a better fit. Follow relevant companies to get job alerts. Let new openings come to you.

Tap Your Network

Don’t just apply cold online. Tell friends, colleagues, and mentors you’re looking. They can connect you directly with hiring managers. Warm introductions help you stand out. Attend industry events and conferences to expand your network.

Customize Your Materials

Go beyond just swapping your resume objective. Personalize cover letters, portfolio samples, and work you highlight. Research the company and role to show why you’re the right solution to their problems.

Prep for Interviews Diligently

Brush up on likely technical and behavioral questions. Practice responses out loud to build confidence. If you have the time and means, do a mock interview with a mentor or coach to sharpen your skills. You want no surprises come interview day.

Send Thank You Notes

Follow up each interview with a thank you email within 24 hours. Thank the interviewer, reiterate your interest, and mention something specific you discussed. This shows appreciation and keeps you fresh in their mind.

Evaluate Offers Carefully

Don’t just take the first offer that comes your way. Compare factors like salary, benefits, growth opportunities, and work culture. Negotiate if the offer is lacking in any area. Make sure the role aligns with your goals before accepting.

Keep Organized Records

Tracking applications is key. Use a spreadsheet to log company, date applied, materials sent, and application status. This keeps you from losing opportunities and helps learn what works.

Avoid Common Pitfalls

Steer clear of mistakes like typos, dishonesty, bad mouthing employers, and using silly fonts. Small oversights can tank your chances. Details matter, so meticulously proofread all materials.

Persist and Stay Positive

The process can get discouraging, especially facing rejection. But keep tweaking your approach and persevering. With dedication, the right fit will come your way. Stay upbeat, learn from any failures, and keep eyes on your dream job.
