How do you understand a company’s culture before you start?

How to Actually Understand a Company’s Culture Before You Join

In this episode of VHTB, Justus Kilian of Space Capital is joined by Seyka Mejeur of AdAstra and Matt Gjertsen of Better Every Day Studios to answer a listener's question: How can you figure out what a company’s culture is really like before accepting a role?

They talk through practical ways to figure that out. what to look for in team backgrounds, how to ask better questions in interviews, and what signals to watch for throughout the hiring process. Seyka shares examples from recruiting and talent advising, where vague or conflicting answers often reflect deeper issues. Matt points out how simple things like whether someone shows up on time or follows through tend to say more than formal mission statements.

They also talk about layoffs, Glassdoor, and how to handle questions about red flags you’ve read about online.

Episode Takeaways

  • Before assessing any company’s culture, be clear on what you’re looking for. Culture fit is personal, not universal.
  • Team patterns, past roles, and interview behavior can reveal more than official messaging.
  • Misalignment across interviews is worth noting. Consistency often signals clarity.
  • A polished values page doesn’t mean much if there’s no real follow-through.
  • Ask direct questions. Also, pay attention to how interviewers behave, not just what they say.
  • Layoffs and negative press can be worth asking about the response often tells you more than the incident itself.
  • Culture exists by default. If it’s not shaped intentionally, it still takes shape just with less clarity.
  • Startups shouldn’t try to appeal to everyone. Strong signals help attract alignment and filter out poor fits.
