What a hiring manager scans for in 15 seconds

Hiring managers quickly scan for practical experience and a deep understanding of machining principles, not just buzzwords. They are looking for evidence that the candidate can handle the demands of the job and avoid costly mistakes. Here’s what they’re looking for:

• Experience with specific materials: Can they work with aluminum, steel, titanium, or other materials required for the job?
• Proficiency with different types of lathes: Are they familiar with CNC, manual, or other types of lathes relevant to the role?
• Knowledge of tooling and setups: Do they understand how to select the right tools and set up machines for different operations?
• Ability to read and interpret blueprints: Can they accurately translate technical drawings into machined parts?
• Understanding of tolerances and precision: Do they know how to achieve tight tolerances and maintain consistent quality?
• Commitment to safety protocols: Are they aware of and adhere to safety guidelines to prevent accidents and injuries?
• Problem-solving skills: Can they troubleshoot issues and find solutions to machining challenges?
• Attention to detail: Do they pay close attention to details to ensure accuracy and prevent errors?

The mistake that quietly kills candidates

The biggest mistake is failing to provide specific examples of machining work and quantifiable results. Candidates who only talk about their responsibilities without showing tangible outcomes are often hiding a lack of experience. The fix is to ask for specific examples and probe deeper into their accomplishments.

Use this when you want to assess a candidate’s experience with a specific type of machining operation.

Interviewer: “Tell me about a time when you had to perform a complex turning operation. What challenges did you face, and how did you overcome them?”

Strong Answer: “I was working on a project involving a stainless steel component with very tight tolerances. The material was prone to work hardening, which made it difficult to achieve the required surface finish. To overcome this, I experimented with different cutting speeds and feeds, and eventually found a combination that minimized work hardening and produced a high-quality part. We reduced scrap rate by 15% on that project.”

Red Flag #1: Vague Answers About Machining Experience

A candidate who can’t provide specific examples of their work is a major red flag. They might be exaggerating their experience or lacking the practical skills needed for the job. Don’t let them get away with generalities; ask for details.

Use this question to probe for specifics when a candidate gives a vague answer.

Interviewer: “You mentioned experience with CNC lathes. Can you describe a specific project where you used a CNC lathe and the results you achieved?”

Red Flag #2: Lack of Understanding of Machining Principles

A skilled Lathe Operator has a solid understanding of machining principles, including cutting speeds, feeds, and tool selection. If a candidate struggles to explain these concepts, they might be lacking the technical knowledge needed to perform the job effectively. Use a simple scorecard to assess their understanding.

Use this scorecard to evaluate a candidate’s understanding of machining principles.

Scorecard: Machining Principles

• Cutting Speeds and Feeds (Weight: 30%): Does the candidate understand how to select appropriate cutting speeds and feeds for different materials and operations?
• Tool Selection (Weight: 30%): Can the candidate choose the right tools for different machining tasks?
• Tolerances and Precision (Weight: 20%): Does the candidate understand how to achieve tight tolerances and maintain consistent quality?
• Troubleshooting (Weight: 20%): Can the candidate identify and resolve common machining problems?

Red Flag #3: Disregard for Safety Protocols

Safety is paramount in a machining environment. A candidate who dismisses safety protocols or demonstrates a lack of awareness is a liability. Prioritize candidates who prioritize safety.

Here’s the tradeoff: Cutting corners on safety might save time in the short run, but it can lead to accidents, injuries, and costly downtime. I choose safety every time because it protects my team and ensures long-term productivity.

Red Flag #4: Inability to Read and Interpret Blueprints

Accurate blueprint reading is essential for producing parts that meet specifications. A candidate who struggles to interpret blueprints or relies on others for guidance is not ready for the job. Here’s a script to address concerns:

Use this when you need to address concerns about a candidate’s blueprint reading skills.

Interviewer: “I noticed that you didn’t mention blueprint reading in your previous role. Can you walk me through how you would interpret a complex blueprint and identify the critical dimensions and tolerances?”

Red Flag #5: Lack of Experience with Specific Materials or Machines

If the job requires experience with specific materials or machines, a candidate who lacks this experience might not be the right fit. While some skills can be learned on the job, a lack of fundamental knowledge can be a major obstacle.

Here’s what I’d do on Monday morning: I would create a skills matrix that lists the required materials and machines, and then assess each candidate’s experience level. This helps me identify any gaps and determine if the candidate is a good fit for the job.
