- Lucas: Luna, I want to talk about something that sounds like a blessing in hiring but might actually be a curse: candidates who can start immediately. Luna: Oh, I know where you're going with this. The empty desk problem. Lucas: Exactly. On the surface, a candidate who says 'I can start next Monday' feels like a gift. No awkward gap, no waiting for a counteroffer, no lost productivity. But a 2024 study from the National Bureau of Economic Research looked at 12,000 hires across 150 firms and found something striking. Luna: What did they find? Lucas: Candidates who started within two weeks of the offer had a 34 percent higher rate of turnover within the first year compared to candidates who gave a standard two-week notice or longer. That's not a small edge — it's a massive signal. Luna: So the very thing hiring managers love — speed — might actually be the thing that costs them later. Lucas: Right. And the study controlled for industry, role seniority, and even salary. The pattern held across the board. Now, there are a few reasons this plays out. First, a candidate who is immediately available often hasn't been fully competed for. If they're that good, why didn't their current employer try to keep them? Why didn't other offers create a start date delay? Luna: Or maybe they're leaving a bad situation — but that desperation can mean they're not being discerning about the next move either. Lucas: Exactly. The NBER data backs that up. In follow-up interviews with a subset of hiring managers, they found that 'immediate start' candidates were more likely to cite 'escape from toxicity' as their primary reason for leaving — and those hires were also more likely to find toxicity in the new role because they hadn't taken time to vet it properly. Luna: So the quick start is a kind of shortcut that bypasses due diligence on both sides. The candidate doesn't investigate the new company deeply, and the hiring manager doesn't probe why someone is so free. Lucas: There's another angle, too: leverage. A candidate who is currently employed and negotiating with you has options. They can say, 'I need two weeks to wrap up projects, and by the way, I have another offer I'm considering.' That creates a healthy tension that often leads to better compensation and better role clarity. The immediate-start candidate often has weak negotiation power. Luna: Which means they might accept a lower salary or a poorly defined role — and that breeds resentment down the line. I've seen it happen. Lucas: So the question becomes: how do you distinguish between a genuinely great candidate who happens to be between roles — maybe they were laid off, maybe they took a sabbatical — versus a red-flag immediate starter? Luna: I think the key is the story behind the availability. If someone says, 'I left my last job three months ago because I wanted to travel and now I'm back,' that's different from 'I'm leaving Friday and I can start Monday.' Lucas: Right. The NBER study actually segmented the data. Among immediate-start hires, those who had been out of work for more than 30 days had a turnover rate closer to the average. The highest risk was the two-day gap — leaving on a Thursday and starting the following Monday. Luna: That's almost like they're running from something. Or running into something without looking. Lucas: So my recommendation — and I've started doing this myself — is to build a deliberate delay into your hiring process. When a candidate says they can start immediately, instead of celebrating, I ask: 'What would you do with two weeks between jobs if you had them?' Their answer tells you a lot. Luna: I love that. And I've got a personal example. I once hired a product manager who told me she couldn't start for six weeks because she was leading a volunteer project she didn't want to abandon. I almost passed because I needed someone fast. That hire ended up being one of the best I ever made. Lucas: That's the perfect counterexample. She had a reason to delay that showed loyalty, commitment, and good judgment. And she had the leverage to ask for a later start because she was confident in her value. Luna: Exactly. So the signal isn't really about the calendar. It's about the story behind the calendar. Lucas: And that's something we can probe in interviews. I ask: 'Walk me through your ideal transition from your current role to this one. What would a perfect handoff look like?' If they say 'I'd like to leave as soon as possible and not look back,' that's a yellow flag. If they say 'I'd want to document my projects, train my replacement, and take a breather before jumping in,' that's green. Luna: So basically, you want the candidate who treats leaving with the same professionalism they'd bring to joining. Lucas: Precisely. And look, I realize this runs counter to the instinct of most hiring managers. We're under pressure to fill seats. But the cost of a bad hire — especially one that leaves within a year — is estimated at three to five times the annual salary. Taking an extra week to find the right candidate is cheap insurance. Luna: And if you're worried about losing the candidate to another offer, you can always make the offer contingent on a start date that works for both sides. I've done that — we agreed on a four-week start and used the time to prep the team. Lucas: That's smart. You're essentially turning a potential weakness into a structured onboarding runway. Luna: You know, this kind of conversation is exactly why I love doing this show. We get to dig into data that challenges conventional wisdom. Lucas: Speaking of which — a quick honest thing. A handful of listeners chip in monthly through buy me a coffee dot com slash fexingo, and that literally funds making these episodes. No ads, no sponsors, just people who find value in what we do. If these conversations have moved your work forward in some small way, that's where you can keep it going. Luna: Yeah, it's a small group already, and it makes a huge difference. Honestly, it's what keeps this ad-free and independent. Lucas: Anyway — back to the empty desk. So we've established that immediate availability is a signal you should interrogate, not celebrate. But there's one more nuance I want to hit. Luna: What's that? Lucas: The counterintuitive flip side: sometimes the best candidate really is free tomorrow. Maybe they were laid off in a restructuring, and they're top-tier talent. The difference is that they have a story that makes sense — they were part of a reduction in force, not a sudden departure. And they've had time to reflect. Luna: So it's not a rule, it's a heuristic. You use the start date as a prompt for deeper questions, not as a filter. Lucas: Exactly. The NBER study didn't say 'never hire someone who starts quickly.' It said 'pay attention.' The same data shows that candidates who started within two weeks but who had been out of work for more than a month — those had average retention. The risk cluster was the 'hot transfer' — leaving one job Friday and starting another Monday. Luna: So the real red flag is the candidate who is running from something rather than running to something. Lucas: That's the headline. And I think it's a useful lens for any hiring manager. Next time a candidate says 'I can start Monday,' don't say 'great.' Say 'tell me about that.' Luna: I'm going to use that line. 'Tell me about that.' It's perfect. Lucas: And if they give you a thoughtful answer, you might have found your person. If they give you a rushed answer, you might have just dodged a bullet.
