There are certainly many, not just one revealing interview questions. Let me give you some examples linked to the quality or trait you might be looking for:
Best lead-in questions
Can you tell me about yourself?
This is always a good introductory question. Ask and then don’t say another thing until they are done. What they actually say is not critical, but how they answer this question is.
Do they focus on personal or professional details? How do they see themselves? Does this view fit into the culture of the company?
What circumstance brings you here today?
This is one of the best opening interview questions ever in our opinion. This open-ended question surprises many candidates. If they do not respond quickly, just sit quietly and wait for the response. Some candidates reveal problems with their current employer, potential insubordination, and both positive or negative character traits.
Why do you want to work for our company/organization?
Not having an answer is a good way to cross off the candidate, and is a common pet peeve of interviewers.
How Would You Solve. . .
Test them. In a professional setting, these are typically hypothetical judgment situations or ones that have actually occurred at the company. They should demonstrate job-specific problem-solving skills.
Don’t be afraid to ask them to solve problems they would face in the first month of their job at the actual interview.
What unique experience or qualifications separate you from other candidates?
Some candidates have interesting characteristics and experiences that will not be exposed without asking a question like this.
Team oriented
How would a previous job team member describe you?
In most cases, the response to this question indicates how the candidate wants you to feel they are perceived by team members and friends. Take notes on the response and then ask, “May I call your best friend and see how they describe you?” You may or may not be interested in taking them. However, the response and body language after the follow-up question can indicate if you received a truthful response. Asking this question near the beginning of the interview helps you get truthful responses for the rest of your time with the candidate.
Results-focused
Tell me about your crowning achievement.
That question not only tells you what energizes the applicant but also helps you figure out if their interests and passions align with yours.
Change agent
What was a major obstacle you were able to overcome in the past year?
Problem-solving is the major topic covered by this question. What kind of thinker is this candidate? What do they tell you about change? Can they do projects on their own or does their manager need to hold their hand? It also confirms how determined they can be toward a project.
Creative spirit
Describe yourself in one word?
The best candidates are the ones who know exactly who they are. That’s why it’s good to ask candidates to describe themselves in just one word.
Don’t judge people on the word they choose, but consider the insight the answer gives into their creative spirit. Pay attention to whether the candidates ponder the question to answer most thoughtfully.

Not afraid to fail
Tell me about your failures.
A good answer to this question is important because it means that the candidate isn’t afraid of taking risks and will admit when things don’t work out.
People always like to tell you about their successes, but they don’t always want to tell you what didn’t work out well.
Take initiative
How will you contribute to the company?
This will highlight their goals for the specific job and which of their skills would be most beneficial for the company. It also will tell you how they see themselves as part of a team. It will also give you insights into their ability to take initiative.
Remember, their goals should match the company. When they deviate, employees leave.
Passionate
What is your ideal job?
This question will help you determine whether or not the person is suitable for the open job.
It also reveals what their passions and strengths are.
Motivated by continuous learning
Tell me about two memorable projects, one success, and one failure.
