Let’s talk about mistakes. We’ve all made them, especially during something as stressful and uncertain as a job search. What matters most, though, is how we learn from them and use that knowledge to move forward. 

This article breaks down some of the biggest missteps we see job seekers make, from résumé concerns to interview slip-ups. These mistakes come up regularly in our work as job coaches and are validated by the hiring managers we partner with.

5. Résumé Mistakes That Cost You Interviews

You’ve probably heard it before: “Tailor your résumé.” Each job you apply for must have a résumé that highlights skills and experiences to match that specific role. A one-size-fits-all résumé doesn’t cut it. Hiring managers aren’t going to spend time searching for the qualifications—if your fit for the position isn’t obvious within seconds, they’re moving on. Studies show hiring managers only view résumés for six to seven seconds. Make it easy on the HR professional to move you forward. 

But not tailoring isn’t the only résumé mistake job seekers make. Sloppy formatting, inconsistent fonts, and typos send the wrong message. If your résumé looks rushed, employers will assume your work will be, too. Chances are, the person reading your résumé is not a résumé expert, so don’t overthink the process. A simple and easy-to-read layout is what matters most. 

Another growing concern? Over-reliance on AI. Tools like ChatGPT can help you get started, but if you submit a résumé that reads like a generic prompt response, hiring managers can tell. Prath Krishnamoorthy, pharma consultant and Hire Heroes USA volunteer, shares, “AI assistance should be used to help with job searches and skills refinement, but the candidate needs to do the work to make it personal to them. Good stories about their accomplishments and leadership are going to be differentiating.”

4. Entering Interviews Unprepared 

3. Unclear Goals and Unknown Skills

One of the biggest slowdowns in a job search? Not knowing what you’re looking for. This starts with a thorough assessment of your skills and qualifications. What are you bringing to the table, and what is the market asking for? If you aren’t clear on the type of role you want, what industries interest you, and how your skills align with those industries, you’ll likely hit a wall in your search or wind up somewhere you don’t enjoy. Skills assessments build your job search trajectory. Even if you feel confident in your skill set, taking time to complete skills assessments can uncover strengths and career paths you may not have considered. 

In the past year, Krishnamoorthy has observed a noticeable shift in job search behavior, with people, “using AI as a crutch for not doing the hard work of defining their skills, the purpose they seek, and why they want a position.” A successful job search starts with clarity. That means understanding your strengths, researching industries and roles, and figuring out where your experience overlaps with what employers need. The time spent before hitting “submit”  can bring you the most return on investment in your job search. 

4. Skipping Out on Networking

“Networking” often feels like a buzzword. It’s not asking people for a job—it’s about having conversations and learning from those who are doing what you want to do. LinkedIn is one of the most impactful places to build these relationships. 

Informational interviews are key to understanding company culture, identifying skills for certain roles, uncovering potential training gaps, and leading to referrals, in some cases. Don’t rush past this step. Submitting applications is important, but building relationships is the precursor to doing so.

Mistakes Happen

Let’s be honest. At some point, everyone has made a mistake during a job search. The good news? Most of them aren’t deal-breakers.

Did you have a typo on your résumé? Not great, but fixable. Did you forget to send a thank-you note after an interview until the next day? Still better late than never. Even stumbling through an interview answer can be followed up with a thoughtful clarification. Krishnamoorthy adds, “I will forgive a badly answered question if the interviewee comes forward and admits they made a mistake. Vulnerability wins for me every time.” 

Own it, learn from it, and keep going. Employers don’t expect perfection, but they do respect self-awareness and follow-through. Demonstrating the confidence to address a mistake head-on shows integrity, transparency, and adaptability. Whether it strengthens your chances with the current employer or better prepares you for the next opportunity, every step brings you closer to the right “yes.”
