You finally found her. The perfect controls engineer. Ten years of experience with Rockwell Automation systems. Background in automotive and pharmaceutical manufacturing. Strong references. Enthusiastic about your project. She was genuinely excited after the initial phone screen.

Then she vanished. Stopped responding to emails. Didn't return calls. A week later, you see her LinkedIn updated with a new position at your competitor.

What happened? You just experienced what's happening to manufacturing companies across the country every single day: accidentally repelling great candidates through well-intentioned but deeply flawed hiring processes.

Here's the frustrating truth: most manufacturing companies don't lose candidates because of salary or benefits. They lose them because of how they treat people during the recruiting process. Slow timelines, chaotic interviews, mismatched expectations, and radio silence create experiences so poor that qualified candidates actively choose to work elsewhere—often for less money.

This article is for HR professionals and hiring managers who are tired of losing good people and don't understand why it keeps happening. We're going to walk through the four most common ways manufacturing companies accidentally sabotage their own recruiting, and more importantly, how to fix each one.

The Death by Delay: How Slow Interview Cycles Kill Your Pipeline

The single biggest way manufacturing companies lose strong candidates is through glacially slow hiring processes. And most hiring managers don't even realize they're moving slowly because they're comparing their timeline to other positions in their company, not to what candidates are experiencing in the broader market.

Here's what commonly happens: A great candidate applies or is sourced. HR takes a week to review the resume and another week to schedule a phone screen. The phone screen goes well, but the hiring manager is traveling for the next week, so scheduling the first interview takes another 10 days. That interview goes great, but now you need to schedule the second interview with the engineering director who's booked solid, so that's another two weeks. Finally, you're ready for the on-site panel interview, but coordinating four people's calendars takes another week. You're now 7-8 weeks into the process and you haven't even made a decision yet, much less extended an offer.

Meanwhile, from the candidate's perspective: they interviewed with your competitor two weeks ago and received an offer last Friday. They've been waiting for some signal from you about timeline, next steps, anything. They've heard nothing. They're not going to wait indefinitely while you leisurely move through your process.

The best automation and controls candidates are typically fielding multiple opportunities simultaneously. They're interviewing with 2-3 companies at once. The company that moves decisively wins. The company that takes two months to make a decision loses, even if they eventually come back with a better offer, because the candidate has already committed elsewhere.

Speed matters more than perfection. It's better to move quickly with a streamlined three-interview process than to move slowly with a comprehensive five-interview process. Yes, you want to assess candidates thoroughly, but every additional week in your timeline dramatically increases the probability you'll lose them.

How to fix this: Establish a target timeline and work backward. For a mid-level controls engineer, you should be able to move from initial contact to offer in 2-3 weeks. This means: phone screen within 48 hours of application, first interview within a week, second interview within a week after that, decision and offer within 2-3 days of final interview. Block time on key stakeholders' calendars in advance for hiring. Treat candidate interviews with the same urgency you'd treat customer meetings. When you find someone strong, accelerate—don't wait for your "normal" process to unfold at its leisurely pace.

The Bait and Switch: When Job Descriptions Don't Match Reality

The second major way companies scare off candidates is through misleading or poorly written job descriptions that create expectations the role can't meet. Candidates get excited about what they read, go through interviews, and then discover the actual job is completely different from what was advertised.

Common disconnects include job descriptions that promise cutting-edge automation work when the reality is maintaining 20-year-old legacy equipment. Postings that emphasize project work and design when 80% of the job is actually troubleshooting and firefighting. Descriptions highlighting modern technology stacks when you're actually running obsolete systems with no modernization budget.

Another version of this problem is the "everything including the kitchen sink" job description. You list every technology, skill, certification, and experience you could possibly want, creating an impossible standard that scares away qualified candidates who don't check every box. Or you write descriptions so vague and generic that they say nothing: "Seeking an experienced automation engineer to support our manufacturing operations. Must have strong communication skills and attention to detail." This tells candidates absolutely nothing about what they'd actually be doing.

The misalignment often happens because the job description was written by HR from a template without meaningful input from the hiring manager, or because the hiring manager listed their fantasy candidate rather than describing the actual role. Either way, when candidates discover the disconnect during interviews, they immediately lose trust. If you weren't honest about the basics of the job, what else aren't you being honest about?

There's also the problem of burying the most important information. You list 15 different responsibilities but don't clarify which are primary focus areas and which are occasional tasks. You mention "competitive salary" but don't give any range, forcing candidates to invest time in multiple interviews before discovering you're $20,000 below market. You talk about the company but say almost nothing about the specific automation projects or technology stack they'd work with.

How to fix this: Have the actual hiring manager write or heavily edit job descriptions based on the real day-to-day work, not some idealized version. Be specific about technology ("You'll program Allen-Bradley ControlLogix PLCs and integrate Fanuc robots") rather than generic ("PLC programming required"). Differentiate must-haves from nice-to-haves clearly. Include realistic salary ranges. Most importantly, be honest about the split between new project work and maintenance/support. Candidates appreciate honesty far more than they appreciate exaggerated promises that don't match reality.

The Technical Interview Disaster: Assessing the Wrong Things the Wrong Way

The third way manufacturing companies lose great candidates is through poorly designed technical interviews that either fail to assess what matters or create unnecessarily adversarial experiences.

On one end of the spectrum are interviews that don't assess technical ability at all. You meet the candidate, ask generic behavioral questions ("Tell me about a time you faced a challenge"), discuss their resume at a high level, and make a hiring decision without ever validating that they can actually do the technical work. Then you're surprised when they struggle after starting.

On the other end are interviews that feel like hazing rituals. You throw obscure technical trivia at candidates ("What's the exact scan time of a CompactLogix 5380 controller?"), give them pop quizzes on things they could easily look up, or design tests that have nothing to do with the actual work they'd be doing. You create an adversarial dynamic where the interviewer is trying to catch the candidate not knowing something rather than genuinely assessing their practical problem-solving ability.

Another common mistake is having the wrong people conduct technical interviews. You have your plant manager or HR director ask technical questions they don't understand, reading from a script someone else wrote. Candidates can immediately tell when interviewers don't actually comprehend the subject matter, and it signals either lack of technical depth in your organization or lack of respect for the role.

There's also the issue of unrealistic assessments. You ask candidates to complete a multi-hour technical project on their own time before you'll even consider them. Or you bring them on-site and expect them to troubleshoot live equipment with zero context or documentation as some kind of test. These approaches might seem rigorous, but they mostly test candidates' willingness to jump through hoops, not their actual competence.

Poor technical interviews also damage candidate experience through unprofessionalism: interviewers who haven't reviewed the resume, who don't have a plan for what they want to assess, who spend the entire time talking at the candidate instead of having a conversation, or who make the interview feel like an interrogation rather than a mutual evaluation.

How to fix this: Design technical assessments that mirror the actual work. For a controls engineer, have them walk through how they'd approach a real automation challenge you've faced: "We need to retrofit this packaging line with vision inspection. Walk me through how you'd approach this project." Listen to their thought process, not just their answers. Have your actual technical people conduct technical interviews—your senior controls engineer or automation manager, not your HR director. Make it conversational: you're assessing their expertise, but you're also selling them on the interesting technical problems they'd get to solve. If you use practical assessments, keep them reasonable (30-60 minutes maximum), make them paid, and ensure they're directly relevant to the role. The goal is mutual evaluation, not torture.

The Black Hole: Poor Communication and Feedback

The fourth way companies lose candidates is through communication failures that make people feel ignored, disrespected, or uncertain about their status.

The most common version is the black hole: candidates interview and then hear nothing for weeks. They don't know if you're still interested, if you've moved forward with other candidates, or if their application somehow got lost. They send follow-up emails that go unanswered. They're left in limbo, which is incredibly frustrating and signals organizational dysfunction.

Another version is the inconsistent communicator: sometimes you respond quickly, other times there's radio silence. Candidates never know what to expect, so they're constantly anxious and checking email. Or different people at your company give conflicting information—HR says one timeline, the hiring manager says something different, creating confusion and concern.

There's also the non-feedback problem. Candidates invest hours in your process, and when you ultimately decide not to move forward, you send a generic rejection email with zero specifics. "We've decided to pursue other candidates. Good luck in your search." They have no idea what went wrong, what they could have done better, or whether they were close or not even in consideration. This is particularly frustrating for candidates who made it to final rounds.

Poor communication also happens during the offer stage. You finally extend an offer but then become non-responsive when the candidate has questions or wants to negotiate. You give them a deadline to respond but don't answer their attempts to discuss details. Or you make the offer verbally but then take forever to produce the written version, leaving the candidate in limbo and making them question whether the offer is real.

The communication failures signal deeper problems to candidates.

If you're this disorganized during recruiting—when you're supposedly trying to impress them—what will it be like to actually work here? If you don't respect their time enough to send a simple status update, how will you treat them as employees? Candidates draw conclusions about company culture from how you treat them during hiring, and those conclusions are often correct.

How to fix this: Establish communication norms and stick to them religiously. Tell candidates upfront what your process looks like and what timeline to expect. Send a quick update even when there's no update: "We're still in process with other interviews. I'll have a concrete update for you by Friday." Assign clear ownership—one person is responsible for keeping each candidate informed. When you reject candidates who've invested significant time (anyone who made it past phone screens), provide brief, honest feedback when possible: "Your technical background was strong, but we ultimately went with someone with more direct experience in pharmaceutical validation."

Close the loop quickly—don't leave people hanging for weeks. When you extend offers, be responsive and collaborative about questions and reasonable negotiation. Treat candidates like valued professional peers, because that's what they are.

The Compounding Effect: How These Issues Reinforce Each Other

Here's what makes these problems particularly damaging: they compound. When you combine slow timelines with poor communication, candidates not only have to wait, they have to wait without knowing what's happening. When you pair misaligned job descriptions with bad technical interviews, candidates feel like they've been baited into wasting their time. When all four issues are present, you've created a candidate experience so poor that people actively warn their networks away from your company.

Manufacturing and automation is a small world. Controls engineers know other controls engineers. Word spreads quickly about which companies have their act together and which ones waste candidates' time. Your reputation in the talent market is being shaped by every candidate experience, not just the people you hire. Every candidate you mishandle is potentially influencing 10-20 people in their network.

The companies that consistently win recruiting battles aren't necessarily those with the best compensation or the coolest projects (though those help). They're the companies that treat candidates professionally, move efficiently, set clear expectations, assess fairly, and communicate transparently. These companies have figured out that candidate experience isn't a nice-to-have; it's a competitive weapon.

Making the Changes Stick

Understanding these problems is the first step. Actually fixing them requires commitment and accountability.

Start by mapping your current hiring process from candidate perspective. How long does each step actually take? Where do communication gaps exist? Who owns what? Identify the bottlenecks and failure points. Get honest feedback from recent candidates—both hired and not hired—about their experience.

Then establish clear standards: maximum time between application and phone screen, maximum time between interviews, communication checkpoints, who's responsible for what. Make these standards visible and track compliance. When you fall behind, course-correct immediately rather than letting delays compound.

Involve your best technical people in designing interview processes and conducting technical assessments. They know what actually matters and they'll create more credible, effective evaluations.

Finally, assign executive sponsorship. When the VP of Operations or VP of Engineering makes it clear that candidate experience matters and asks about it in staff meetings, behavior changes. When it's just HR asking people to move faster, it's easy to ignore. When senior leadership signals this is a priority, people find time.

The Bottom Line

Manufacturing companies are losing great candidates not because of salary or benefits, but because of self-inflicted process problems that are entirely fixable. Slow timelines, misaligned expectations, poor technical assessment, and communication failures combine to create experiences so bad that qualified candidates actively choose to work elsewhere.

The good news is that you can differentiate yourself significantly just by being professionally competent. Move efficiently, set honest expectations, assess fairly, and communicate consistently. These aren't revolutionary ideas; they're basic professional standards. But in a market where most companies fail at these basics, doing them well gives you a massive competitive advantage in attracting the manufacturing and automation talent you need.

Your competitors are making these mistakes right now. The question is whether you'll keep making them too, or whether you'll fix your process and start winning the recruiting battles that matter.
