Team Lead interview question · Most asked
What is psychological safety, and how do you build it?
Summary
The belief that you can take interpersonal risks — admit mistakes, ask questions, challenge ideas — without being punished or embarrassed. You build it mostly through how you react: modelling fallibility, thanking people for bad news, inviting input structurally and addressing behaviour that undermines it.
Longer Answer
Google's Project Aristotle studied 180 teams and found how a team works together matters more than who is on it, with psychological safety the most important of five dynamics (then dependability, structure and clarity, meaning and impact). Practical moves: ask juniors first, silent writing before discussion, blameless postmortems, a quarterly pulse question like "if I make a mistake on this team, it is not held against me". Safety doesn't mean comfort — safe teams disagree more openly.
