A CEO and former Googler shares the interview question she's asked every applicant at her 50-person company

At online bra company ThirdLove, curiosity is one of the most important company values ' something every new hire has to display.But flat out asking a job candidate if they're a curious person is hardly the best way to find out whether they really are. (Who would say no')According to Heidi Zak, former Google senior marketing manager and cofounder, along with her husband Dave Spector, of ThirdLove, there's one question she asks every single job candidate to assess their level of curiosity:"One year from now, if you're part of the team at ThirdLove, how will you judge if [your time here] has been a success'"The ideal answer would start off something like, "It's all about learning new things and about growing professionally."Zak and Spector founded ThirdLove in 2013; since then the company has raised over $13 million in funding, according to Crunchbase, and grown to 50 employees.Zak said hiring has been one of the hardest parts of building the company.To make sure they didn't bring on anyone who wasn't a personality fit, ThirdLove's leadership team identified a set of core company values. Beyond curiosity, those values include being positive, responsible, adaptive, and being able to put the customer first.Then they developed specific questions ' like the one mentioned above ' to see whether each candidate "inherently possess those values in their personality," Zak said.Ra'el Cohen, ThirdLove's vice president of design and product development, shared another question the team uses to assess personality fit: "What was the last mistake that you and your last team made and what did you learn from it'"They're looking for the candidate to use the word "I" instead of "we" ' to take ownership and responsibility for the mess-up instead of blaming it on others."That's a real telltale sign," Cohen said."In a startup, you need to own your own world," Zak added. "If they don't do that, then that's very much a red flag."SEE ALSO:19 psychological tricks that will help you ace a job interviewJoin the conversation about this storyNOW WATCH: Google stopped asking these 7 job interview questions because they were so tricky
