The most common hiring mistakes aren’t about bad judgment. They’re defaults: an interview process that drags, a search that waits for applicants to show up, a job description built from a wish list, and a pay range set from last year’s budget. Each one quietly narrows your options, but each one is fixable.

Hiring is something most managers do a few times a year. For our recruiters, it’s every day. They’re on the phone with candidates weighing competing offers, working alongside hiring managers through interview debriefs, and watching in real time which approaches land great people and which ones lose them.

We’re sharing the hiring mistakes we see most often, and what the companies that hire well do instead.

Hiring Mistake #1: A Hiring Process That Moves Slower Than the Market

A slow hiring process is the most common reason companies lose top candidates. Strong talent does not stay on the market long, with active candidates often receiving multiple offers within weeks. When interviews are spread out and feedback lags, a competitor with a faster process usually wins. The fix is a shorter process with clear decision criteria.

The most common issues the cause a slow interview process are:

• Four or five interview rounds that involve multiple people’s schedules that do not align
• Interviewers who weren’t on the same page on what “good” looks like causing friction during internal evaluation
• Feedback that sits in someone’s inbox for days
• An offer that needs multiple approvals

“A multi-step interview process is normal, especially for senior positions,” explains Jessica Heilweil, a Managing Director at Top Stack with over a decade of recruiting experience.

“When we anticipate multiple rounds of interviews, there should be an emphasis on candidate experience, which includes setting clear timelines, and providing timely feedback throughout the process. Ideally this means that subsequent interviews are within days of one another, and do not exceed three rounds. This helps keep the process moving, keeps the candidate engaged, and helps avoid losing good people along the way.”

How to speed things up:

• Set the timeline before you post the role. Block interview slots for the full panel in advance so scheduling never becomes the bottleneck.
• Cap the process at three touchpoints for most individual contributor roles: a screen, a skills or technical conversation, and a final meeting with the decision maker.
• Agree on a scorecard up front. When every interviewer knows the three or four things they’re evaluating, feedback takes minutes instead of days.
• Commit to a max 48-hour feedback rule after every interview and tell candidates when they’ll hear back.
• Pre-approve the offer range so you can extend an offer the same day you decide.

Once you’ve developed a speedy process, be sure to set expectations with candidates so they can plan accordingly. Heilweil shares how candidates can feel undervalued when they invest time and energy into an interview process but are left waiting for feedback or clarity on next steps.

“I had a candidate who was the client’s clear first choice after round one, but a second interview was required with a different decision maker. No problem! But feedback on that interview was slow to come, and we were unsure of next steps. Meanwhile, the candidate was wrapping up another interview process with a different company. By the time the client aligned internally and extended an offer, the candidate had accepted another position. My candidate’s response: ‘The other company just made me feel wanted.’”

Outlining the interview process and timeline with candidates and having an established internal feedback loop is essential to creating a respectful and efficient interview process for everyone involved.

Hiring Mistake #2: Relying Only on Job Posting

Job postings mostly reach people who are actively looking – but that doesn’t mean they reach the best people. If you’re recruiting strategy fully relies on talent finding you, you’re missing out on a whole other talent pool of highly skilled candidates who are employed, performing well, but are not scrolling the job boards.

These candidates are often open to new opportunities when the right one presents itself. To reach them, you need direct outreach through networks, referrals, and recruiters.

“Some of the strongest professionals in any market aren’t looking for a job. They’re performing well, they’re respected, and they’re busy. A job board is the last place they’ll spend their time,” offers Sarah Brumbley, Principal at Top Stack who has developed hundreds of custom recruiting strategies for clients over 20 years.

But that doesn’t mean they aren’t open to making a move. Brumbley goes on to say that with the right approach, passive candidates can be engaged and responsive.

“Access to these candidates changes the whole search. Instead of choosing the best of whoever applied, you’re choosing from people who are proven in their current roles and who are considering you on purpose.”

How to reach passive candidates:

• Ask your team for referrals early. Your best people usually know other strong performers in their field.
• Reach out directly. Use LinkedIn and industry groups to contact professionals in similar roles at peer companies.
• Stay visible in your local professional community. CPA societies, tech meetups, and industry associations build a pipeline before you need it.
• Lead outreach with what’s in it for them. Passive candidates respond to growth, impact, and flexibility, not a list of requirements.
  
  

Hiring Mistake #3: Writing Job Descriptions That Screen Out Great Candidates

Job descriptions with unnecessary requirements shrink your talent pool by discouraging qualified people from applying.

This may look like:

• Degree or certification requirements that are nice to have, where practical skills matter more
• Unnecessary experience requirements, such as 3+ years in a specific tool for a role that a strong one-year professional could grow into
• A list of ten “required” skills when the job really depends on only three or four

“I ask every hiring manager the same question: if a candidate had everything on this list except one or two items, would you still interview them? The answer is almost always yes,” says Heilweil.

“That tells me that some items are a preference, not a requirement. I’ll help the client refine their job description to reach a better audience.”

How to loosen requirements while still attracting top talent:

• Start with outcomes, not credentials. Write down what success looks like at 90 days and one year, then list only the skills needed to get there.
• Separate “must have” from “nice to have” and keep the must-have list short.
• Make degrees and certifications optional unless the role legally or practically requires them.
• Read the job description like a candidate: would a strong professional in this field see themselves in this description, or see a reason not to apply?

In Heilweil’s experience, many of the skills listed as “required” can be learned in the first few months with the right mentorship.

“For instance, in a finance or accounting role, if someone knows one ERP system, they can learn another. The same goes for a specific reporting tool or the nuances of your industry. What’s much harder to teach is judgment, strong fundamentals, and the ability to explain analysis to someone outside of finance. I’ve heard from many hiring managers that finding the right person for the role often outweighs having every technical skill on day one.”

Hiring Mistake #4: Setting Pay Without Current Market Data

Pay ranges based on last year’s budget or a predecessor’s salary often fall below what candidates expect today. That leads to declined offers and restarted searches. Benchmarking each role against current local data before posting keeps searches on track.

“Salary surveys tell you what the market looked like when the data was collected. I’m seeing offers, counteroffers, and acceptances every week,” reports Brumbley.

“When a client’s range is off, I’m up front with them about that so we can consider reworking the role by adjusting a combination of compensation, flexibility, seniority, or skill requirements.”

How to create a competitive offer:

• Benchmark every role at the start of the search, not after the first offer is declined.
• Look at the whole package. Hybrid flexibility, growth paths, bonus structure, and benefits often weigh as heavily as base pay, especially for experienced candidates.
• Build a range you can defend. With pay transparency expanding, a posted range needs to reflect what you’re actually prepared to pay.
• Revisit bands for hard-to-fill roles at least once a year. Finance and technology markets can shift faster than annual budget cycles.

Knowing the market before you start hiring saves weeks of effort and protects your credibility with candidates.

How a Staffing Agency Can Enhance Your Recruiting Strategy

A staffing agency gives hiring managers three things that are hard to build in-house: access to candidates who aren’t actively looking, current local market data, and the flexibility to match the hiring model to the work. The right partner doesn’t replace your judgment – they’ll give you better options, faster, so your team can focus on choosing the right person.

Access to talent you won’t find through a job posting

Recruiters build relationships with professionals long before a role opens, including people who are thriving in their current jobs and not searching. These personal relationships provide context that create strong matches: career goals, job preferences, compensation parameters, soft skills, etc.

Most importantly, these passive candidates will pick up the phone when their trusted recruiter calls because they know the opportunity is worth their while.

A faster path to a strong shortlist

Because a recruiter starts with an existing network of vetted professionals, you can see qualified candidates within days instead of weeks.

Recruiters screen for skills, dig into past work, and verify preferences before presenting anyone. That means instead of sifting through hundreds of applications, you only see a list of the best candidates that are already aligned with your expectations.

A good partner also keeps candidates engaged between interview rounds and tells you plainly when your timeline is putting a top choice at risk.

Local compensation insight

Regional recruiters see real compensation packages every week. That insight gives you a current read on what it takes to land a candidate, plus early warning when a range is likely to stall your search.

Job descriptions that attract the right people

Recruiters know which requirements are shrinking your candidate pool. A good partner will challenge requirements that don’t hold up, help you separate what can be taught on the job from what can’t, and present strong candidates who fit the work even if they don’t match the posting word for word.

The best staffing partners work like an extension of your hiring team. They widen your candidate pool, sharpen your process, and give you the market insight to make confident decisions.

Turn the Question Into a Competitive Advantage

Each of these fixes compound to earn you something no job posting can buy: a reputation as the kind of employer top professionals want to work for.

A faster process keeps strong candidates engaged. A wider search brings better people into that process. A sharper job description attracts the right applicants, and an informed offer closes them.
