A candidate who is fishing for a counteroffer will pass almost every interview you put in front of them. They are polished, available, and agreeable, because they are not interviewing for the job. They are interviewing for ammunition to take back to their current boss. The interview is a two-way read, and most leaders only run it in one direction: they ask whether the candidate is good enough. The sharper question is whether you can read intent at all. That skill, the ability to underwrite a person's actual motivation, is the lever. Candidate quality is not what protects you here. Your own diagnostic discipline is.

In construction, where the people you want are already employed and rarely looking, this miss is expensive. You spend hours finding, interviewing, and negotiating, and the candidate carries your offer back to their boss as bargaining power and stays put. The cost is not just the wasted weeks. It is the better, more committed person you stopped looking for because you thought you had your hire.

So underwrite intent the way you would underwrite a subcontractor's bid: assume the number on paper is the easy part, and go looking for what it is hiding. Five patterns tell you when a candidate is fishing rather than moving.

1. Vague or evasive about why they are leaving

A genuinely motivated candidate has concrete reasons: stalled growth, an unstable company, a culture they have outgrown, a leader they no longer trust. Someone fishing gives you fog instead:

  • "Just exploring what's out there."
  • "I've been thinking about making a move for a while."
  • "I'm not unhappy, but I'd be open to the right opportunity."

Fog usually means they are not dissatisfied. They are curious about their market value, and you are the appraisal.

Pressure test it: "If this doesn't move forward, what's your next step in your search?" If the answer is "I'm not actively looking" or "I haven't thought about it," you are looking at curiosity, not commitment.

2. Fixated on compensation before anything else

Money is real, and a serious person will get to it. But when a candidate leads with pay in the first conversation, before the role, the work, or the people, read it as a signal. They may be assembling a number to carry back to their employer.

  • "What's the absolute highest you'd go?"
  • "I'd consider leaving if you could beat my current salary by at least 20 percent."

Pressure test it: "Beyond pay, what matters most to you in the next role?" If they struggle to answer, the offer letter was the point.

3. Still mentally inside their current company

People ready to leave have already detached. They talk about their current job in the past tense. Someone fishing keeps circling back to their boss, their projects, their place in the plan, because they have not actually left in their head.

  • "I really like my boss, but..."
  • "My company has been great to me, I'm just curious."
  • "I'm central to some major projects, so the timing would have to be right."

Pressure test it: "If your company matched or exceeded this offer, what would you do?" If they hesitate or need to think about it, they are not ready to leave.

4. Reluctant to move at any real speed

Decisive candidates move because they know what they want. A candidate who keeps rescheduling, stalls on simple follow-ups, and dodges questions about timing is usually buying time, waiting to see whether their employer will counter.

  • Rescheduling interviews more than once.
  • Taking days to answer a one-line question.
  • Avoiding anything specific about start dates or availability.

Pressure test it: "On a scale of one to ten, how ready are you to move if this is the right fit?" Anything below an eight deserves a second look.

5. Acts surprised by a counteroffer, then takes it

Some candidates claim they never saw the counter coming, then accept it within a day. The surprise is theater. They were never fully in the room.

  • "I had no idea my company would fight this hard to keep me."
  • "I wasn't expecting this counter, but now I'm torn."
  • "I feel like I owe it to them to stay."

Pressure test it, early: "How will you handle a counteroffer from your current employer?" A serious person says, "I'm ready to move on." Someone fishing says they would have to think about it. Ask this in the first conversation, not the last.

Why this lands on you, not them

When a candidate plays this game and you miss it, the bill goes everywhere. Your team burns weeks interviewing and negotiating. The genuinely committed person you could have hired goes elsewhere. The search drags, and confidence in it erodes.

The candidate did not waste your time. The unasked question did.

None of these patterns are exotic. They are visible in the first two conversations to a leader who is reading for intent instead of reading for likeability. The fishing candidate is not the problem to solve. The mirror is: are you running the interview as a one-way audition, or as an underwrite, where the hardest questions come early and a soft answer is information rather than an inconvenience.

You can spot every one of these in week one if you are willing to ask the question that risks ending the conversation.
