Coding interviews are comprised mainly of data structure and algorithm-based questions as well as some of the logical questions such as, How do you swap two integers without using a temporary variable? There are a lot of computer science graduates and programmers applying for programming, coding, and software development roles at startups like Uber and Netflix. Once you have gone through these questions, you should feel confident enough to attend any telephonic or face-to-face interviews. Without any further ado, here is my list of some of the most frequently asked coding interview questions from programming job interviews :.

Coding interviews are comprised mainly of data structure and algorithm-based questions as well as some of the logical questions such as, How do you swap two integers without using a temporary variable? There are a lot of computer science graduates and programmers applying for programming, coding, and software development roles at startups like Uber and Netflix. Once you have gone through these questions, you should feel confident enough to attend any telephonic or face-to-face interviews.
Without any further ado, here is my list of some of the most frequently asked coding interview questions from programming job interviews :. An array is the most fundamental data structure, which stores elements at a contiguous memory location. It is also one of the darling topics of interviewers and you will hear a lot of questions about an array in any coding interview , e.
In order to create a shorter or longer array, you need to create a new array and copy all elements from old to new. The key to solving array-based questions is having a good knowledge of array data structure as well as basic programming constructors such as loop, recursion, and fundamental operators.
Here are some of the popular array-based coding interview questions for your practice:. These questions will not only help you to develop your problem-solving skills but also improve your knowledge of array data structure.
And, if you feel 10 is not enough questions and you need more practice, then you can also check out this list of 30 array questions. A linked list is another common data structure that complements the array data structure. Similar to the array, it is also a linear data structure and stores elements in a linear fashion. A linked list is nothing but a list of nodes where each node contains the value stored and the address of the next node. This article provides more information on the difference between an array and linked list data structures.
It also comes in varieties like a singly linked list, which allows you to traverse in one direction forward or reverse ; a doubly linked list , which allows you to traverse in both directions forward and backward ; and finally, the circular linked list, which forms a circle. In order to solve linked list-based questions, a good knowledge of recursion is important, because a linked list is a recursive data structure. If you take one node from a linked list, the remaining data structure is still a linked list, and because of that, many linked list problems have simpler recursive solutions than iterative ones.
Here are some of the most common and popular linked list interview questions and their solutions:. These questions will help you to develop your problem-solving skills as well as improve your knowledge of the linked list data structure.
If you are having trouble solving these linked list coding questions then I suggest you refresh your data structure and algorithms skill by going through Data Structures and Algorithms: Deep Dive Using Java course. You can also check out this list of 30 linked list interview questions for more practice questions.
Along with array and linked list data structures, a string is another popular topic on programming job interviews. I have never participated in a coding interview where no string-based questions were asked. A good thing about the string is that if you know the array, you can solve string-based questions easily because strings are nothing but a character array.
So all the techniques you learn by solving array-based coding questions can be used to solve string programming questions as well. Here is my list of frequently asked string coding questions from programming job interviews:. These questions help improve your knowledge of string as a data structure. If you can solve all these String questions without any help then you are in good shape. For more advanced questions, I suggest you solve problems given in the Algorithm Design Manual by Steven Skiena , a book with the toughest algorithm questions.
If you need more practice, here is another list of 20 string coding questions. Tree data structure is a data structure that allows you to store your data in a hierarchical fashion. Depending on how you store data, there are different types of trees, such as a binary tree , where each node has, at most, two child nodes. Therefore, you will find a lot of questions based on them, such as how to traverse them, count nodes, find depth, and check if they are balanced or not.
A key point to solving binary tree questions is a strong knowledge of theory, e. Here is a list of popular binary tree-based coding questions from software engineer or developer job interviews:. If you need some more recommendations, here is my list of useful data structure algorithm books and courses to start with. Having practiced them before not only makes you familiar with them but also gives you more confidence in explaining the solution to the interviewer. A good book to prepare for programming job interviews in a short time.
By the way, the more questions you solve in practice, the better your preparation will be. So, if you think 50 is not enough and you need more, then check out these additional 50 programming questions for telephone interviews and these books and courses for a more thorough preparation.
These are some of the most common questions outside of data structure and algorithms that help you to do really well in your interview. I have also shared a lot of these questions on my blog , so if you are really interested, you can always go there and search for them.
These common coding, data structure, and algorithm questions are the ones you need to know to successfully interview with any company, big or small, for any level of programming job. If you are looking for a programming or software development job in , you can start your preparation with this list of coding questions.
This list provides good topics to prepare and also helps assess your preparation to find out your areas of strength and weakness. Thanks, You made it to the end of the article … Good luck with your programming interview!

DAA Interview Questions and Answers
What are Divide and Conquer algorithms? Describe how they work. Can you give any common examples of the types of problems where this approach might be used? Divide and Conquer algorithms are a paradigm for solving problems that involve several basic steps. First, we divide the problem into smaller pieces and work to solve each of them independently. This recursive division of the problem is performed until each individual problem is small enough to become relatively trivial to solve. Some common examples of problems that lend themselves well to this approach are binary search, sorting algorithms e.
