Tell Me About A Time That You Dealt With A Hostile Customer

Answering 5 Amazon Interview Questions About Problem Solving

When interviewers ask about a time you dealt with a hostile customer, they are looking to see how you handle difficult situations. They want to know if you can remain calm under pressure and whether you can think on your own. The best way to answer this question is to share an example of a time when you could successfully de-escalate the situation. You can talk about the steps you took to diffuse the situation and how you managed to keep the customer happy.

Why Does Amazon Use Case Study Interviews

Amazon uses case study interviews because your performance in a case study interview is a measure of how well you would do on the job. Amazon case interviews assess a variety of different capabilities and qualities needed to successfully complete job duties and responsibilities.

Amazons case study interviews primarily assess five things:

  • Logical, structured thinking: Can you structure complex problems in a clear, simple way?
  • Analytical problem solving: Can you read, interpret, and analyze data well?
  • Business acumen: Do you have sound business judgment and intuition?
  • Communication skills: Can you communicate clearly, concisely, and articulately?
  • Personality and cultural fit: Are you coachable and easy to work with?

Since all of these qualities can be assessed in just a 20- to 30-minute case, Amazon case study interviews are an effective way to assess a candidates capabilities.

In order to do well on the personality and cultural fit portion, you should familiarize yourself with before your interview. At a high level, these principles include:

  • Customer obsession: Leaders start with the customer and work backwards
  • Ownership: Leaders are owners and act on behalf of the entire company
  • Invent and simplify: Leaders expect and require innovation and invention from their teams and always find ways to simplify
  • Learn and be curious: Leaders are never done learning and always seek to improve themselves
  • Frugality: Accomplish more with less

Amazon Behavioral Questions: 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.

Amazon is an enormous company, and its employees need to build products and structures that reach significant scale in order to make a difference for the business. As a result, interviewers will want to see that you can develop and articulate a bold vision.

Example behavioral questions asked at Amazon: Think big

  • Tell me about your most significant accomplishment. Why was it significant?
  • Tell me about a time you proposed a non-intuitive solution to a problem and how you identified that it required a different way of thinking
  • What was the largest project you’ve executed?

Discuss The Most Difficult Problem You Have Ever Dealt With

This question is designed to assess your problem-solving skills and ability to think on your feet. The best way to answer this question is to discuss a problem you were passionate about solving. You should describe the problem in detail and explain how you approached it. Talk about the challenges you faced and how you overcame them. Be sure to highlight your accomplishments and what you learned from the experience.

Insist On The Highest Standards

How To Solve Amazon

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.

Practice questions on the highest standards:

Amazon expects their employees to always be striving to reach higher standards. They want to see employees who have pushed themselves to meet difficult goals and who will continue to do so in the future.

This is one of the things that makes Amazon such a great place to work. It is a company that is always looking to challenge its employees and help them grow. Employees at Amazon always feel like they are learning and growing, which helps to keep them motivated and engaged.

Merge Two Sorted Linked Lists

Given two sorted linked lists, merge them so that the resulting linked list is also sorted. Consider two sorted linked lists and the merged list below them as an example.

def merge_sorted:  #TODO: Write - Your - Code  return head1

Click here to view the solution in C++, Java, JavaScript, and Ruby.

Runtime Complexity: Linear, O where m and n are lengths of both linked lists

Memory Complexity: Constant, O O

Maintain a head and a tail pointer on the merged linked list. Then choose the head of the merged linked list by comparing the first node of both linked lists. For all subsequent nodes in both lists, you choose the smaller current node and link it to the tail of the merged list, and moving the current pointer of that list one step forward.

Continue this while there are some remaining elements in both the lists. If there are still some elements in only one of the lists, you link this remaining list to the tail of the merged list. Initially, the merged linked list is NULL.

Compare the value of the first two nodes and make the node with the smaller value the head node of the merged linked list. In this example, it is 4 from head1. Since its the first and only node in the merged list, it will also be the tail.Then move head1 one step forward.

Which Is More Important: Money Or Work

In my point of view work is more important to me. Once you achieve and overperform the target and help increase the company’s growth, then definitely money will follow.

Copy Linked List With Arbitrary Pointer

You are given a linked list where the node has two pointers. The first is the regular next pointer. The second pointer is called arbitrary and it can point to any node in the linked list. Your job is to write code to make a deep copy of the given linked list. Here, deep copy means that any operations on the original list should not affect the copied list.

def deep_copy_arbitrary_pointer:   #TODO: Write - Your - Code  return None

Click here to view the solution in C++, Java, JavaScript, and Ruby.

Runtime Complexity: Linear,

This approach uses a map to track arbitrary nodes pointed by the original list. You will create a deep copy of the original linked list in two passes.

  • In the first pass, create a copy of the original linked list. While creating this copy, use the same values for data and arbitrary_pointer in the new list. Also, keep updating the map with entries where the key is the address to the old node and the value is the address of the new node.
  • Once the copy has been created, do another pass on the copied linked list and update arbitrary pointers to the new address using the map created in the first pass.

The presence of a Bar Raiser:

Amazon also has a special âBar Raiserâ round, where specially trained employees gauge if youâre the right fit. The primary function of the Bar Raisers is to maintain the hiring bar high by seeking out only the best talent. They have a decisive say in the interviewâs outcome, so if you ace the core technical rounds and Amazon coding challenge questions, you must pass the bar raiser round to lock an offer.

To become a bar raiser, an interviewer should have done 100+ interviews. The bar raiser has to undergo special training and shadow other bar raisers. The bar raiser may not be from the team youâd be joining, but they may be under the same VP org. The bar raisers evaluate if the candidate is better than 50% of the existing employees.
