Amazon SQL Interview Questions — Big Tech Interviews

Amazon is a company that needs no introduction. From what started out as a small e-commerce store that sold books in 1994 to becoming one of the largest employers in the world with over 41 different subsidiaries and brands.

Amazon has experienced tremendous growth since its inception and has continued to hire roles such as Amazon business analyst, data analyst, and data scientist.

Fun fact: Every two years, Amazon employees from C-suite to recent graduates spend two days working in the customer department.

The Amazon Analyst Interview Process

Whether you’re interviewing for a business analyst, data analyst, data engineer, or data scientist role, you’re probably going to have a similar interview format.

  • Leetcode, Big Tech Interviews, or Stratascratch are going to help you pass your technical screening.
  • 1 Leadership Principle = 1 Relevant SMART example.

The Amazon Tech Interview Format

Round 1: Recruiter Phone Screen

The recruiter phone screen is typically 30–60 minutes. The goal of the phone screen is to make sure you meet the basic qualifications and requirements for the job.

Types of questions to expect during your phone screen:

This sounds like a pretty standard interview process, right?

WRONG! This is a common rookie mistake.

While your interviewer needs to get these questions out of the way, they’ll also be analyzing you for a cultural fit. Make sure you’re ready to talk about the Amazon Leadership Principles at a high level.

Lastly, during this initial interview process, it’s a great opportunity to build rapport with the recruiter and pick up pieces of information as to why they’re hiring for this role.

This knowledge will help you decide which examples to use in subsequent interview rounds.

Round 2: Technical Assessment

The technical interview typically lasts from 30–60 minutes and depending on the role may include not only SQL interview questions using SQL server but also Python and data management questions.

Round 3: Onsite (Final round)

The final round is an all-day interview consisting of 4–5 consecutive interviews.

There are typically 1–2 technical interviews where they gauge your technical abilities with SQL and occasionally Python and there are 2–3 behavioral interviews.

Additionally, expect to be interviewed by a bar raiser, this individual will usually be a senior manager and often times from a different segment of the business.

Their primary objective is to ensure the candidates who get offers are at a minimum 50% better than the current employees at Amazon. Their emphasis is largely around behavioral and cultural fit as they believe most individuals can come up to speed with their technical skills assuming they’ve passed the initial tech screens.

This interviewer will be the decision-maker so make sure you’re prepared with examples of how you’ve demonstrated the 16 different Amazon leadership principles.

The technical interviews will be similar to the initial coding screen with a slight twist.

Expect these technical interviews to be a level deeper than your initial technical assessment.

The interviewers will be assessing your weak points from your last technical interview so make sure you’ve ironed out your weak points and are ready to ace the assessments.

Remember to speak slowly, clarify the questions, and walk them through the logic behind your solutions.

This last step is often overlooked. It’s not unheard of for someone to get an offer due to their logic, even though they might have not solved the problem correctly.

Finally, make sure to brush up on your statistics, mathematics, database management, and data engineering questions such as ETL pipelines.

The behavioral interviews will primarily focus surrounding Amazon’s 16 Leadership Principles.

It’s extremely important that you have examples for each of these principles.

Try using the STAR format to streamline your examples,

This simple framework will help you be precise and check the boxes the interviewer is looking for.

It’s unlikely you’ll be expected to work with the same stack as a data scientist.

After this step, there will potentially be a reference check, but that is typically for more senior-level roles.

What are Amazon’s 16 leadership principles?

  1. Customer Obsession: 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.
  2. Ownership: 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.”
  3. Invent and Simplify: 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.
  4. Right, A Lot: Leaders are right a lot. They have strong judgment and good instincts. They seek diverse perspectives and work to disconfirm their beliefs.
  5. Learn and Be Curious: Leaders are never done learning and always seek to improve themselves. They are curious about new possibilities and act to explore them.
  6. Hire and Develop the Best: 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.
  7. Insist on the Highest Standards: Leaders have relentlessly high standards — many people may think these standards are unreasonably high. Leaders are continually raising the bar and drive 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.
  8. Think Big: 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.
  9. Bias for Action: Speed matters in business. Many decisions and actions are reversible and do not need extensive study. We value calculated risk taking.
  10. Frugality: Accomplish more with less. Constraints breed resourcefulness, self-sufficiency, and invention. There are no extra points for growing headcount, budget size, or fixed expense.
  11. Earn Trust: 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.
  12. Dive Deep: 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.Right, A Lot: Leaders are right a lot. They have strong judgment and good instincts. They seek diverse perspectives and work to disconfirm their beliefs.
  13. Have Backbone; Disagree and Commit: 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.
  14. 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.
  15. Leaders work every day to create a safer, more productive, higher performing, more diverse, and more just work environment. They lead with empathy, have fun at work, and make it easy for others to have fun. Leaders ask themselves: Are my fellow employees growing? Are they empowered? Are they ready for what’s next? Leaders have a vision for and commitment to their employees’ personal success, whether that be at Amazon or elsewhere.
  16. Success and Scale Bring Broad Responsibility: We started in a garage, but we’re not there anymore. We are big, we impact the world, and we are far from perfect. We must be humble and thoughtful about even the secondary effects of our actions. Our local communities, planet, and future generations need us to be better every day. We must begin each day with a determination to make better, do better, and be better for our customers, our employees, our partners, and the world at large. And we must end every day knowing we can do even more tomorrow. Leaders create more than they consume and always leave things better than how they found them.
