领导力法则

围绕亚麻14条principle准备,最好明显说出来符合哪条principle。每一条原则用心揣摩理解,准备约两个故事,通过约15-20个故事覆盖,把故事的技术细节准备得极详细

Customer Obsession 顾客至上

giving the customer what they want before they know they want it

Leaders start with the customer and work backwards. They work vigorously to earn and keep customer trust. Although leaders pay attention to competitors, they obsess over customers.

  • Who was your most difficult customer?

  • Give me an example of a time when you did not meet a client’s expectation. What happened, and how did you attempt to rectify the situation?.

  • When you’re working with a large number of customers, it’s tricky to deliver excellent service to them all. How do you go about prioritizing your customers’ needs?

  • Tell the story of the last time you had to apologize to someone.

Ownership 主人翁精神

Leaders are owners. They think long term and don't sacrifice long-term value for short-term results. They act on behalf of the entire company, beyond just their own team. They never say "that's not my job."

  • Tell me about a time when you had to leave a task unfinished.

  • Tell me about a time when you had to work on a project with unclear responsibilities.

Invent and Simplify 创新简化

Leaders expect and require innovation and invention from their teams and always find ways to simplify. They are externally aware, look for new ideas from everywhere, and are not limited by "not invented here." As we do new things, we accept that we may be misunderstood for long periods of time.

  • Tell me about a time when you gave a simple solution to a complex problem.

  • Tell me about a time when you invented something.

Are Right, A Lot 决策正确

Leaders are right a lot. They have strong business judgment and good instincts. They seek diverse perspectives and work to disconfirm their beliefs.

  • Tell me about a time when you were wrong.

  • Tell me about a time when you had to work with incomplete data or information..

Learn and Be Curious 好奇求知

Leaders are never done learning and always seek to improve themselves. They are curious about new possibilities and act to explore them.

  • Tell me about a time when you influenced a change by only asking questions.

  • Tell me about a time when you solved a problem through just superior knowledge or observation.

Hire and Develop the Best 选贤育能

Leaders raise the performance bar with every hire and promotion. They recognize exceptional talent, and willingly move them throughout the organization. Leaders develop leaders and take seriously their role in coaching others. We work on behalf of our people to invent mechanisms for development like Career Choice.

Insist on the Highest Standards 最高标准

Leaders have relentlessly high standards—many people may think these standards are unreasonably high. Leaders are continually raising the bar and driving their teams to deliver high-quality products, services, and processes. Leaders ensure that defects do not get sent down the line and that problems are fixed so they stay fixed.

  • Tell me about a time when you couldn’t meet your own expectations on a project.

  • Tell me about a time when a team member didn’t meet your expectations on a project.

Think Big 远见卓识

Thinking small is a self-fulfilling prophecy. Leaders create and communicate a bold direction that inspires results. They think differently and look around corners for ways to serve customers.

  • Tell me about your proudest professional achievement.

  • Tell me about a time when you went way beyond the scope of the project and delivered.

Bias for Action 崇尚行动

You might have the best idea to refactor the codebase in your head, but if it never moves towards implementation, it’s worthless

Speed matters in business. Many decisions and actions are reversible and do not need extensive study. We value calculated risk taking.

  • Describe a time when you saw some problem and took the initiative to correct it rather than waiting for someone else to do it.

  • Tell me about a time when you took a calculated risk.

  • Tell me about a time you needed to get information from someone who wasn’t very responsive. What did you do?

Frugality 勤俭节约

Accomplish more with less. Constraints breed resourcefulness, self-sufficiency and invention. There are no extra points for growing headcount, budget size, or fixed expense.

Earn Trust 赢得信任

Leaders listen attentively, speak candidly, and treat others respectfully. They are vocally self-critical, even when doing so is awkward or embarrassing. Leaders do not believe their or their team’s body odor smells of perfume. They benchmark themselves and their teams against the best.

  • What would you do if you found out that your closest friend at work was stealing?

  • Tell me about a time when you had to tell someone a harsh truth.

Dive Deep 刨根问底

Leaders operate at all levels, stay connected to the details, audit frequently, and are skeptical when metrics and anecdote differ. No task is beneath them.

  • Give me two examples of when you did more than what was required in any job experience.

  • Create elastalert rules, not only the rules, but also automate them.

  • Create a vis timeline to visual the tickets.

Have Backbone; Disagree and Commit 敢于谏言,服从大局

I verbalize the things I disagree on. Then I commit to taking action. Whether it was the action you or I proposed doesn’t matter

Leaders are obligated to respectfully challenge decisions when they disagree, even when doing so is uncomfortable or exhausting. Leaders have conviction and are tenacious. They do not compromise for the sake of social cohesion. Once a decision is determined, they commit wholly.

  • Tell me about a time when you did not accept the status quo.

  • Tell me about an unpopular decision of yours.

  • Tell me about a time when you had to step up and disagree with a team members approach.

  • If your direct manager was instructing you to do something you disagreed with, how would you handle it?

Deliver Results 达成业绩

Leaders focus on the key inputs for their business and deliver them with the right quality and in a timely fashion. Despite setbacks, they rise to the occasion and never settle.

  • By providing an example, tell me when you have had to handle a variety of assignments. Describe the results.

  • What is the most difficult situation you have ever faced in your life? How did you handle it?

  • Give me an example of a time when you were 75% of the way through a project, and you had to pivot strategy–how were you able to make that into a success story?
