Tell me about a time you failed. How did you deal with the situation
Participating in previous successful initiatives increases your likelihood of performing well in the Google behavioral interview. People view failure differently; they are not drawn to it. Additionally, candidates are hesitant to face up to their errors.
But Google recruiting managers go one step further and look at it differently. They want to know about the times you've failed, taken risks and made blunders. Your goal is to demonstrate to the interviewer that you are conscious of your shortcomings. They're also curious about the lessons you've taken away from these errors. Giving the example of a thoughtful initiative that went wrong because of inadequate preparation or an underestimate of the risks associated is a great way to respond to this question.
This shows the interviewer that you can take ownership of a situation, learn from it, and use those lessons in the future.
