My final onsite interview ended at 5:45 PM. As I was walking out, I intentionally took the slow route through the open-plan engineering floor. It was 6:00 PM on a Thursday.

Every single desk was occupied. People weren't chatting or playing ping-pong; they were wearing noise-canceling headphones, staring intensely at IDEs, eating sad salads out of plastic containers. The air felt heavy. I realized immediately that "we don't track hours" actually meant "we expect you to work all of them."

The lie of "Unlimited PTO"

Startups love to weaponize flexibility. They offer Unlimited PTO because it removes the financial liability of paying out accrued vacation when you leave. But more insidiously, it relies on peer pressure to keep you at your desk. When there is no baseline expectation of what "normal" time off looks like, nobody wants to be the person who takes the most.

If you want to know the truth about a company's work-life balance, you have to ignore the HR policies and look at the behavioral defaults. You have to apply the 6 PM Test.

How to run the test remotely

In a remote or hybrid world, you can't always walk through the office. But the digital footprints are just as loud. Here is how you run the 6 PM Test during a remote interview process.

1. The Timestamp Audit
Look at the emails you receive from the hiring manager and the team. Are they consistently sending you interview feedback or scheduling requests at 9:30 PM? Are they replying to your follow-ups on Sunday morning? If the manager is working on Sunday, they will eventually expect you to work on Sunday.

2. The "Typical Tuesday" Question
Do not ask, "What is the work-life balance like here?" Everyone lies to that question. They will say, "It's a startup, so we work hard, but we respect boundaries."

Instead, ask this: "Walk me through your exact schedule last Tuesday. When did you log on? When did you log off? Did you check Slack after dinner?"

People are terrible at lying about specific, mundane details. If they stutter, or if they say, "Well, last Tuesday was weird because we had a fire drill..." and then admit they worked until midnight, pay attention. In a toxic startup, every Tuesday is a fire drill.

3. The Vacation Reality Check
When they mention Unlimited PTO, ask the hiring manager directly: "That's great. How many days of PTO did you personally take last year?"

If the leader of the team took four days off in 12 months, that is the actual cap for the team. You will not be allowed to take three weeks to go to Japan, no matter what the employee handbook says.

Hard work vs. Fake work

To be clear: working at a startup requires hard work. There will be late nights before a launch. There will be weekend pages when the database falls over. That is the contract you sign when you take the equity.

But there is a massive difference between episodic hard work driven by real business needs, and a culture of "performative suffering" where leaving at 5:30 PM is viewed as a lack of dedication.

The best startups I've worked for were intense, but the founders logged off at 6 PM to see their kids. The worst ones had catered dinner at 7:30 PM to make sure you never left. Choose wisely.
