Over the past few weeks, a surprising number of people have argued about a cup of iced coffee. Specifically, whether a candidate should carry one into a job interview. The debate over Gen Z job interviews went viral, pulled in every generation and landed in HR newsrooms.

It is easy to laugh at. I think it is worth taking seriously.

Not because of the coffee. Because of what the argument reveals about how we decide who is ready to be trusted with work.

Key takeaways

  • The iced coffee debate is a disagreement about signals, not standards. It is about what a cup communicates, not whether a candidate can do the job.
  • Hiring has become a two-way exercise in reading signals, and new research suggests job seekers are worn out by it.
  • Candidates are evaluating employers from the first touchpoint. The application process itself is a signal they read.
  • Leaders who name the standards they actually hire for make interviews fairer and more useful for candidates of every generation.

What’s happening

The debate started with a TikTok video. As Brian Phillips explains in his September 30 piece for The Ringer, how the iced coffee question became a litmus test, a recruiter named Caitlin Wehniainen posted on September 16 that candidates arriving with iced coffee look “a little too casual.” Her description: “It looks like you went to Target, then you went to Starbucks, now you’re stopping by your interview.” Phillips notes that the conversation grew large enough that The New York Times put two reporters on it, and he places it against a tightening job market, citing July Labor Department data that showed 200,000 fewer openings than economists had forecast.

HR Dive picked up the thread the same day. In its look at how the iced coffee debate exposed generational differences, Caroline Colvin describes the argument spreading across TikTok, Instagram, Facebook and LinkedIn, with Gen Z, Millennials, Gen X and Baby Boomers all weighing in. The piece cites Boston University facilitator and researcher Jeff LeBlanc, who points to COVID-19 lockdowns, remote work and masks as part of the context young workers learned in. His conclusion is not that Gen Z communicates better or worse than earlier generations. In his words, “they have simply learned to do so in a very different environment.”

A day earlier, HR Dive’s Kathryn Moody reported on Indeed’s survey of exhausted job seekers. Indeed surveyed more than 1,500 U.S. job seekers. More than half of Gen Z and Millennial applicants said they stopped mid-application, often because of length and redundancy. About half of all job seekers said they spend more time trying to make an employer think they are right for the job than considering whether the employer is right for them. Among Gen Z respondents, 60% agreed. Indeed’s advice to hiring managers was to “streamline the way they gather information about candidates.”

Put those stories side by side. On one side of the table, an interviewer reading a cup as a sign of seriousness. On the other, candidates spending their energy performing fit instead of assessing it.

Both sides are managing impressions. Neither side is learning very much.

Why Gen Z job interviews have become a standards vs. signals problem

In Chapter 13 of The Next Turn, “Building a Shared Definition of Good Work,” I draw a distinction that I think explains this entire debate.

Standards and signals are not the same thing.

The Next Turn

Standards are what the organization actually needs: quality, reliability, accountability, sound judgment, follow-through, care and contribution. Signals are the visible cues we use to infer those standards: time, presence, responsiveness, polish, visible effort.

An interview is almost entirely signals. We have thirty or sixty minutes to guess whether someone will be reliable, thoughtful and accountable for years. So we lean on cues. A firm handshake. A pressed shirt. Arriving early. Empty hands.

Some of those cues once carried real information, because almost everyone was working from the same unwritten rulebook. When everyone knew the rule, breaking it told you something.

That is what has changed. Ask the recruiter what the cup signals, and the answer is a lack of seriousness. Ask many candidates, and the answer may be nothing at all. Same object. Two different definitions of what professional looks like.

This is what I call the first turn. In the book I describe two changes happening at once. The first is the definition of work: what people believe work is for, what it should provide and what it should look like. The second is the structure of work: how work actually flows, increasingly reshaped by AI. The iced coffee debate sits squarely in the first. It is a disagreement about belief, not capability.

In Chapter 3, “What Each Generation Believes Work Is,” I make the case that generational friction is rarely about style. It is about different beliefs about work, and none of those beliefs are irrational. I also borrow a caution from Pew Research Center: generational labels are broad reference points, not precise boxes. Plenty of Gen Z candidates would never carry a drink into an interview. Plenty of experienced professionals carry coffee into every meeting they attend. The question is not which generation is right.

Hiring is where the collision shows up first

In Chapter 11, “Where It Breaks,” I name hiring as one of four pressure points where the double transition becomes operational. Candidates are evaluating the exchange the role offers, and the meaning of the role often goes untranslated.

The Indeed findings show what that feels like from the candidate’s side. Long, repetitive applications. Pressure to look right rather than to find the right fit. In Chapter 4, “Why Does This Feel Different?”, I put it this way:

Organizations do not get loyalty upfront. They get scrutiny upfront.

The Next Turn

That scrutiny is not only about pay. It is about process. A redundant application is a signal. An interviewer who fixates on a cup instead of the answers is a signal. Candidates read those cues as clues about what it will be like to work there.

So the signal-reading cuts both ways. A candidate who walks in with an iced coffee may be telling you very little about their judgment. An employer who asks for the same information three times may be telling the candidate a great deal.

This is not about lowering the bar

I want to be careful here. Separating standards from signals does not mean that anything goes.

The standards remain. The proof system changes.

The Next Turn

If presentation matters for a role, because it is client-facing or the setting is formal, say so. That is a standard you can name, explain and hold. What erodes trust is the unspoken rule that quietly screens out people who never knew it existed. Making the expectation explicit is fairer to the candidate and more useful to you, because you stop measuring who knew the rulebook and start measuring who can do the work.

That is the broader burden I write about throughout the book. Leaders now have to make explicit what used to be assumed. Hiring is one of the first places that burden shows up, because it is the first conversation an organization has with someone about what work means there.

Your next turn

Here are five moves to try with your hiring team this week:

  1. List your interview signals. Write down the cues your interviewers actually react to: dress, punctuality, eye contact, small talk, thank-you notes. Next to each, name the standard it is supposed to represent. Ask whether there is a more direct way to see that standard.
  2. Say the non-negotiables out loud. If something matters in your setting, put it in the interview invitation. An expectation candidates know about is a standard. One they have to guess is a trap.
  3. Take your own application. Time it. Count how often you ask for the same information. The process is the first signal candidates receive about how you value their time.
  4. Ask for reasoning, not just polish. Have candidates walk you through a real decision they made, what they weighed and what they would change. Judgment is the standard most roles need, and it rarely shows up in a first impression.
  5. Calibrate across generations. In your next debrief, ask each interviewer which cue influenced them most, and whether it predicts anything about the work. You will often find you are weighing different signals without realizing it.

Frequently asked questions

Is it unprofessional for Gen Z candidates to bring coffee to a job interview?

It depends on the norms of the organization, and those norms are no longer shared by default. Some recruiters read it as too casual, while many candidates see it as meaningless. If it matters in your setting, tell candidates in advance. Otherwise, focus your evaluation on evidence of the standards the role actually requires.

What is the difference between standards and signals in hiring?

Standards are what the job truly requires, such as reliability, sound judgment, accountability and quality. Signals are the visible cues we use to guess at those standards, like dress, punctuality rituals or polish. A signal is only useful when it reliably points to the standard behind it.

How can managers interview candidates across generations more fairly?

Define the standards for the role before interviews begin, use the same structured questions for every candidate and ask people to explain the reasoning behind past decisions. Then talk as a panel about which cues you may be over-weighting. Generational labels are broad reference points, not predictions about any individual.

The coffee will be forgotten in a month. The question underneath it will not.

Every hiring process runs on a definition of good work, whether anyone has written it down or not. The organizations that hire well in this era will be the ones that know the difference between what they need and what they are used to seeing.

So here is my question for you: which of your hiring signals would still hold up if you had to explain them to the candidate sitting across the table?
