What a Hiring Manager Scans for in 15 Seconds

Hiring managers quickly assess whether you understand the core responsibilities of a Professional Engineer and can handle the pressure. They look for specific keywords and examples that demonstrate your technical expertise, project management skills, and ability to collaborate effectively. The goal is to quickly assess if you have the foundational requirements to perform the job, and if you have any glaring gaps.

Here’s what they scan for:

• Certifications: PE license, PMP, or other relevant credentials.
• Technical skills: Proficiency in specific software, tools, and engineering methodologies.
• Project experience: Examples of successfully completed projects, including scope, budget, and timeline.
• Problem-solving abilities: Examples of how you’ve overcome challenges and resolved conflicts.
• Communication skills: Ability to clearly and concisely communicate technical information to both technical and non-technical audiences.

The Mistake That Quietly Kills Candidates

Vague statements without quantifiable results are a death knell for Professional Engineer candidates. Saying you “improved efficiency” or “managed projects effectively” is meaningless without concrete evidence. Hiring managers need to see the impact of your work in terms of cost savings, time reduction, or increased productivity. This is lethal because it signals you don’t understand the link between activities and outcomes. You’re perceived as someone who executes tasks without understanding the larger business context.

Do this: Quantify your accomplishments with specific metrics and data. For example, “Reduced project completion time by 15% by implementing a new workflow management system.”

Use this when rewriting your resume bullets.

Instead of: “Managed project budgets effectively.”
Try: “Managed project budgets ranging from $500k to $2M, consistently delivering projects within budget and achieving an average cost savings of 8%.”

Red Flag #1: Lack of Technical Depth

A superficial understanding of engineering principles raises concerns about your ability to solve complex problems. If you can’t articulate the technical details behind your work, hiring managers will question your expertise. This is especially true in specialized fields like structural, electrical, or mechanical engineering.

Do this: Be prepared to discuss the technical aspects of your projects in detail. Explain the engineering principles you applied, the challenges you faced, and the solutions you implemented. If you’re talking about a mechanical system, be able to discuss the materials, loads, and stresses involved.

Red Flag #2: Inability to Quantify Results

Failing to provide concrete metrics to support your claims makes it difficult to assess your impact. Engineering is a data-driven field, and hiring managers want to see that you can measure your success. Without numbers, your accomplishments are just empty words.

Do this: Always quantify your achievements with specific metrics. For example, “Reduced energy consumption by 10%”, “Improved production throughput by 15%”, or “Reduced defect rate by 5%.”

Red Flag #3: Poor Communication Skills

Struggling to communicate technical information clearly and concisely can hinder your ability to collaborate effectively. Professional Engineers often need to explain complex concepts to non-technical audiences, such as clients, stakeholders, and regulators. If you can’t communicate effectively, you’ll struggle to get your ideas across and build consensus.

Do this: Practice explaining technical concepts in simple terms. Use visual aids, such as diagrams and charts, to illustrate your points. Be prepared to answer questions from non-technical audiences.

Red Flag #4: Lack of Project Management Experience

Demonstrating insufficient experience in managing engineering projects signals an inability to oversee complex tasks and deliver results on time and within budget. This doesn’t necessarily mean you need to be a certified project manager, but you should be able to speak to the principles of project management: planning, execution, monitoring, and closure.

Do this: Highlight your experience in managing projects, including your role in planning, executing, monitoring, and closing projects. Explain how you managed risks, resolved conflicts, and ensured that projects were completed on time and within budget.

Red Flag #5: Failure to Take Ownership

Blaming others for project failures or avoiding responsibility for your mistakes suggests a lack of accountability. Hiring managers want to see that you can own your work and learn from your mistakes. This doesn’t mean you have to take the fall for everything, but you should be willing to acknowledge your role in any setbacks.

Do this: Be honest about your mistakes and explain what you learned from them. Focus on the steps you took to correct the problem and prevent it from happening again.

Use this script when discussing a past project failure.

“In [Project Name], we encountered a significant challenge when [briefly describe the issue]. While several factors contributed to this, I recognize that my [specific action or inaction] could have been handled differently. Specifically, [explain what you would do differently now]. To prevent similar issues in the future, I’ve implemented [specific changes to your process or approach]. As a result, in subsequent projects, we’ve seen [positive outcome, e.g., a reduction in errors or improved communication].”

Red Flag #6: Arrogance and Overconfidence

Presenting yourself as a know-it-all or dismissing the opinions of others can alienate potential colleagues. Engineering is a collaborative field, and hiring managers want to see that you can work effectively with others. Arrogance suggests that you’re not open to learning and that you may be difficult to work with.

Do this: Be confident in your abilities, but also be humble and respectful of others’ opinions. Acknowledge that you don’t have all the answers and that you’re always willing to learn.

Red Flag #7: Lack of Enthusiasm

Appearing uninterested in the role or the company raises questions about your motivation. Hiring managers want to see that you’re passionate about engineering and that you’re genuinely excited about the opportunity to work for their company. Lack of enthusiasm can signal that you’re just looking for a paycheck or that you’re not truly committed to the field.

Do this: Research the company and the role thoroughly. Be prepared to discuss why you’re interested in the opportunity and what you hope to accomplish. Show genuine enthusiasm for the work.

Red Flag #8: Poor Research on the Company

Failing to demonstrate knowledge of the company’s projects, values, or challenges suggests a lack of preparation. Hiring managers expect you to have done your homework and to understand the company’s mission and goals. Without this knowledge, you’ll struggle to articulate why you’re a good fit for the organization.

Do this: Research the company’s website, social media channels, and news articles. Identify the company’s key projects, values, and challenges. Be prepared to discuss how your skills and experience can contribute to the company’s success.

Red Flag #9: Inability to Discuss Past Failures

Avoiding discussing past failures or providing generic answers suggests a lack of self-awareness. Every engineer experiences setbacks, and hiring managers want to see that you can learn from your mistakes. Avoiding the topic or blaming others raises concerns about your accountability and your ability to grow.

Do this: Be prepared to discuss a past failure in detail. Explain the situation, your role in the failure, what you learned from it, and how you’ve applied those lessons to future projects.

Red Flag #10: Not Asking Questions

Failing to ask thoughtful questions at the end of the interview suggests a lack of curiosity and engagement. Asking questions demonstrates that you’re genuinely interested in the role and the company, and that you’re thinking critically about the opportunity. Not asking questions can signal that you’re simply going through the motions.

Do this: Prepare a list of thoughtful questions to ask at the end of the interview. Focus on questions that demonstrate your understanding of the role and the company’s challenges. For example, “What are the biggest challenges facing the engineering team right now?” or “How does the company measure the success of its engineering projects?”

Red Flag #11: Presenting Solutions Without Understanding the Problem

Jumping to solutions without thoroughly understanding the problem demonstrates a lack of analytical skills. Professional Engineers are problem-solvers, and hiring managers want to see that you can approach challenges in a systematic and logical way. Offering solutions without understanding the underlying issues suggests that you’re not thinking critically.

Do this: Before offering solutions, take the time to understand the problem thoroughly. Ask clarifying questions, gather data, and analyze the situation. Demonstrate that you can approach challenges in a systematic and logical way.

Red Flag #12: Over-Reliance on Jargon

Using excessive technical jargon without explaining it demonstrates a lack of communication skills and can alienate non-technical audiences. While technical expertise is important, it’s equally important to be able to communicate complex concepts in simple terms. Over-reliance on jargon can suggest that you’re trying to impress the interviewer or that you’re not comfortable explaining your work to others.

Do this: Use technical jargon sparingly and always explain it in simple terms. Remember that your goal is to communicate effectively, not to impress the interviewer with your vocabulary.

Red Flag #13: Inconsistent Resume and Interview Narrative

Discrepancies between your resume and your interview answers raise red flags about your honesty and attention to detail. Hiring managers want to see that your resume accurately reflects your skills and experience, and that your interview answers align with your written claims. Inconsistencies can suggest that you’re exaggerating your accomplishments or that you’re not being truthful.

Do this: Review your resume carefully before the interview and ensure that your interview answers are consistent with your written claims. Be prepared to explain any discrepancies or inconsistencies.

Red Flag #14: Ignoring Safety Protocols

Failing to prioritize safety or demonstrating a lack of knowledge of safety protocols raises serious concerns about your ethics and risk management skills. Safety is paramount in engineering, and hiring managers want to see that you’re committed to creating a safe working environment. Ignoring safety protocols can suggest that you’re reckless or that you’re not taking your responsibilities seriously.

Do this: Emphasize your commitment to safety and your knowledge of relevant safety protocols. Be prepared to discuss how you’ve implemented safety measures in past projects and how you’ve addressed safety concerns.

Red Flag #15: Not Knowing Your Worth

Inability to articulate your value and negotiate a fair salary can signal a lack of confidence and business acumen. Hiring managers want to see that you understand your worth and that you’re willing to advocate for yourself. Not knowing your worth can suggest that you’re not confident in your abilities or that you’re not taking your career seriously.

Do this: Research industry salary benchmarks and be prepared to discuss your salary expectations. Articulate your value proposition and explain why you deserve a fair salary.
