Question Overview: This question is designed to see how well a candidate understands the difference between Code-First and Database-First method.
Sample Answer: Code-First is a development approach in which you write your code first and then create your database. Database-First is a development approach in which you create your database first and then write your code.
Question Overview: This is a basic computer science question that tests a candidate's knowledge of data structures and algorithms.
Sample Answer: A linked list is a data structure that contains a series of nodes. Each node contains a value and a pointer to the next node in the list. The last node in the list contains a pointer to null, which is used to indicate the end of the list.
Question Overview: This question is designed to test the candidate's knowledge of Java and their ability to articulate their experience with the language.
Sample Answer: I've been working with Java for the last five years. I've worked on a number of different projects using Java, from web applications to desktop applications. I've also worked on a few Android apps using Java.
Question Overview: This question is designed to test a candidate's knowledge of data structures and their ability to implement them.
Sample Answer: I would create a class called Stack that would have two private variables: a pointer to the top of the stack and an integer that represents the number of items in the stack. The constructor would take two parameters: the number of items in the stack and the pointer to the top of the stack. The push() method would take a single parameter, which is the item to be added to the stack. The pop() method would take no parameters and return an item from the stack. The min() function would take no parameters and return an integer representing the minimum value in the stack.
Question Overview: This question is designed to test the candidate's problem-solving skills and their ability to think outside the box.
Sample Answer: I would first try to find the highest value that the first number could be. Then I would try to find the lowest value that the second number could be. Then I would try to find a range of values for both numbers that would sum to the target value.
Question Overview: This question is designed to see how well a candidate can communicate outside of their professional life. It also gives you insight into what they do for fun and how they spend their free time.
Sample Answer: I like to go running in the mornings, and I'm a big fan of the New York Yankees. I also like to read books on history and politics, and I'm a member of the local library.
Question Overview: This is a basic coding question that tests the candidate's knowledge of the most common string functions.
Sample Answer: I would use a for loop to iterate through each character in the string and use a switch statement to check if the character is a letter or not. If it is a letter, I would add it to the end of the reversed string, and if it isn't, I would add a space to the end of the reversed string.
Question Overview: This question is designed to see how well a candidate can think through a problem, and how they would implement a solution.
Sample Answer: A least recently used cache is a cache that stores the least recently used items in memory. This is useful for applications that have a lot of traffic and need to keep the most frequently accessed items in memory. The first step in designing a LRU cache is to determine what data structure you will use to store the items. I would use a hash table with a size of 2^n, where n is the number of items in the cache. The next step is to determine how you will determine if an item is least recently used. I would use a timestamp on each item in the cache, and then use that timestamp to determine if an item was least recently used.
Question Overview: This question tests a candidate's ability to think through a problem and come up with a solution.
Sample Answer: I would start by drawing a map of the current Amazon locations. Then I would look at the map and try to find patterns in where they are located. I would then try to find a pattern in the new proposed locations and see if there is a way to optimize the placement of new stores.
Question Overview: This question is designed to see if the candidate is honest and forthcoming. It also gives you insight into what they didn't like about their previous job.
Sample Answer: I'm leaving my current job because I'm looking for a new challenge. I've been at my current job for three years and I've learned all that I can from my current position. I'm ready for a new challenge and to learn new things.
Question Overview: This question is designed to see how a candidate handles conflicts. Are they able to resolve conflicts in a professional manner or do they get defensive and aggressive?
Sample Answer: I try to resolve conflicts by talking through the issue with the other person and coming up with a solution that works for both of us. I've found that it's best to be honest and upfront about my feelings and concerns, rather than letting them fester and boil over into an argument.
Question Overview: This question tests how well a candidate can think on their feet and how well they can solve a problem in a short amount of time.
Sample Answer: I would start by writing down all the pairs of integers that sum up to the target number. Then I would go through each pair and count how many times it occurs. Then I would divide the target number by the count of each pair to get the average number of occurrences. Finally, I would take the average number of occurrences and multiply it by the target number to get the total number of distinct pairs.
Question Overview: If the candidate is willing to relocate for the job, it may be a sign that they are desperate for a job and will take any offer that comes their way.
Sample Answer: I am willing to relocate for this job.
Question Overview: This question is designed to test a candidate's knowledge of object-oriented programming.
Sample Answer: The features of OOP are inheritance, polymorphism, encapsulation, and abstraction.
Question Overview: This question is designed to test a candidate's knowledge of programming concepts.
Sample Answer: Function overloading is when a single function has multiple definitions with different parameters. This allows the same function to be used in multiple ways.
Question Overview: This question is designed to see if the candidate is willing to relocate to the city you are in or if they have a specific location they want to live in.
Sample Answer: I am willing to relocate anywhere in the United States.
Question Overview: This question is designed to test a candidate's knowledge of the .NET framework.
Sample Answer: The Common Language Runtime (CLR) is the environment in which .NET applications execute. It is a virtual machine that provides services that are used by the application. It is responsible for memory management, exception handling, security, and other services.
Question Overview: This is a great opportunity to learn more about the candidate and what they're looking for in a job.
Sample Answer: I'm an avid runner and enjoy spending my free time reading and watching movies. I'm also a big fan of the New York Yankees.
Question Overview: This question is designed to test an applicant's knowledge of data structures and algorithms.
Sample Answer: I would use a binary search tree or a hash table to find the kth most frequent word in a string. I would use a binary search tree because it is more efficient than a hash table.
