Hello guys, if you are preparing for your next Programming Job interview and looking for frequently asked Coding or Programming questions to practice then you have come to the right place. In this article, I am going to share some of the most commonly asked Coding questions from Programming Job interviews. In order to do well on the Coding interview you need practice, you just can't go there and try to solve the coding problems in a limited time, that's actually one of the most common reasons to fail your programming Job interviews. Sometimes, the interviewer also asks a little bit easier coding questions on a telephonic interview like revering array in place or reversing a string in place.
Sometimes, when you hear these popular coding questions the first time in the interview, you stumble because of nervousness and lack of preparation and that's where knowledge of popular coding questions is important before going for any programming job interviews.
Most of the coding questions are based upon data structures like an array, string, linked list, binary tree, etc, but sometimes you also get algorithmic, tricky, logical, and scenario-based questions like how to swap two integers without using a temp variable or how to check if two rectangles overlap on each other or not.
That's why I have divided this list of coding problems into five categories, mean array-based coding questions, string-based questions, linked list questions, binary tree questions, and other miscellaneous questions, where you will find questions on bit manipulation, design, tricky, logical and other miscellaneous topics.
Btw, good knowledge of Data Structure and Algorithm is essential, and even though you will learn a lot of new concepts by solving these questions, I suggest you first refresh your knowledge of Data Structure and algorithms before attempting these questions by joining a comprehensive course like Data Structures and Algorithms: Deep Dive Using Java on Udemy.
There is no point in attempting these questions if you don't have sufficient knowledge of data structure and Algorithms.
The questions are more like you find in the popular book Cracking the Coding Interview by Gayle Lakmann Mcdowell, one of the essential books to do well on a Job interview, but more focus on Data Structure and Coding rather than touching every single possible topic required for a programming job interview like SQL, UNIX, Database, Networking, etc, for that, you need to read books and you can find many good titles here.
We'll start the list by first exploring array-based questions like finding pairs whose sum is given a number and then move to string-based questions, linked list-based questions, binary tree questions, and finally tackler other topics.
If you don't know, an array is a data structure that holds other objects like String, int, float, etc. It holds them in a contiguous location in memory which makes them easily searchable and retrieval in O(1) time using the index.
Insertion and deletion of an array are tough because you cannot change the size of an array once created and you need to create a new array and copy elements from old to new.
Anyway, here are some of the most popular array-based coding interview questions for your preparation:
1. How to find the missing number in a given integer array of 1 to 100? (solution)
2. How to find the duplicate number on a given integer array? (solution)
3. How to find the largest and smallest number in an unsorted integer array? (solution)
4. How to find all pairs of integer arrays whose sum is equal to a given number? (solution)
5. How to find duplicate numbers in an array if it contains multiple duplicates? (solution)
6. How to remove duplicates from a given array in Java? (solution)
7. How to sort an integer array in place using the QuickSort algorithm? (solution)
8. How to remove duplicates from an array in place? (solution)
9. How to reverse an array in place in Java? (solution)
10. How to find multiple missing numbers in a given integer array with duplicates? (solution)
I have linked all the solutions but you should try to solve them by yourself before looking at the solution, especially if you have time. That's the only sure way to learn to program by solving these coding questions.
If you find these questions difficult to solve then once again I suggest you first refresh your knowledge of fundamental data structures like an array by going through a comprehensive course. If you need recommendations, Algorithms, and Data Structures Part 1 and Part 2 by Robert Harvick are two of the best course to start with. You will also learn about Big(O) notation and how to calculate time and space complexity.
If you think these 10 questions from the array are not enough and you are interested in solving more array-based programming problems then you can also check out these 30 array-based coding questions for more practice.
The string is implemented differently in a different programming language like in C it's a NULL-terminated character array but in Java, it's an object. However, you can still get access to the underlying array to apply your logic.
Here is a list of some of the frequently asked coding questions which are based on String. Though some of them are quite old, you can still expect this in your programming job interview:
11. How to Print duplicate characters from String? (solution)
12. How to check if two Strings are anagrams of each other? (solution)
13. How to print the first non-repeated character from String? (solution)
14. How to reverse a given string using recursion? (solution)
15. How to check if a string contains only digits? (solution)
16. How to find duplicate characters in a String? (solution)
17. How to count a number of vowels and consonants in a given String? (solution)
18. How to count the occurrence of a given character in String? (solution)
19. How to find all permutations of String? (solution)
20. How to reverse words in a given sentence without using any library method? (solution)
21. How to check if two String is a rotation of each other? (solution)
22. How to check if the given String is Palindrome? (solution)
Similar to an array, I have also linked to a solution for all of these String problems but if you want to get most of this article, you better solve these questions without looking at the answers. Only when you are stuck and running out-of-time, you can look at the solution.
And, if you find these frequently asked String problems difficult to solve, maybe it's time to go back to the drawing board and learn the fundamentals of String data structure again. If you need resources then Data Structures and Algorithms Specialization on Coursera is one of the best online resources you can use to make your foundations rock solid.
You can also learn from it by comparing your solution with the solution I have given. It's not necessarily to be the same but you can learn a lot by comparing them and if you need more practice, here is another list of 20 String algorithm questions and this list of 21 String coding problems21 String coding problems for tech interviews.
It's also the counterpart of an array data structure. While array stores elements on contiguous memory locations, the linked list stores them at different locations and finds them by storing their address. a linked list is made of nodes, an internal data structure that holds the value as well as the address of the next node.
Because of its structure, it's easier to add and remove elements from the linked list like on O(1) time if you are adding or removing from the head but the search is equally difficult and takes O(n) time, as you have to literally walk through each element.
Anyway, here is a collection of some of the simple and tricky linked list based coding questions for your practice:
23. How to find the middle element of a singly linked list in one pass? (solution)
24. How to check if a given linked list contains a cycle? How to find the starting node of the cycle? (solution)
25. How to reverse a linked list? (solution)
26. How to reverse a single linked list without recursion? (solution)
27. How to remove duplicate nodes in an unsorted linked list? (solution)
28. How to find the length of a singly linked list? (solution)
29. How to find the 3rd node from the end in a singly linked list? (solution)
30. How do you find the sum of two linked lists using Stack? (program)
Similar to array and string, I have also linked to all the solutions but you should only look at them once you solved the problem on your own or you feel stuck.
A key to solving the linked list is a good understanding of recursion because a linked list is a naturally recursive data structure, for example, if you take one node out of the linked list, the result is another linked list, but many programmers struggle to understand recursion.
That was the case with me as well but after practice and visualizing how recursion really works, I overcome that deficiency. If you are in the same boat, I strongly suggest you go through a visual course like Visualizing Data Structures and Algorithms in Java to learn Recursion and data structure. That will help you a lot in your thought process and problem-solving skills.
Once you understand recursion, most of the linked list based problems have an easy recursive solution than their iterative version. And if you need more practice, here is another list of 30 linked list programming questions for your reference.
There are a lot of different types of trees e.g. a binary tree, binary search tree, AVL tree, Red-Black tree, etc but Binary tree and Binary search trees are also known as BST are two of the most popular ones and most of the questions are based upon them.
Some questions are also based upon theoretical knowledge of tree data structure e.g. finding the height of the tree, finding leaf nodes, checking if the tree is balanced or not, etc, hence you should also spend some time learning the basics, along with practicing coding questions.
Anyway, here is a list of popular binary tree and binary search tree based coding questions to practice before your job interview:
30. Can you write a program to implement a binary search tree? (solution)
31. How do you perform Pre-order traversal in a given binary tree? (solution)
32. Write a Program to traverse a given binary tree in Pre-order without recursion (solution)
33. How to perform an In order traversal in a given binary tree? (solution)
34. How to print all nodes of a given binary tree using inorder traversal without recursion (solution)
35. How to implement a Post-order traversal algorithm? (solution)
36. How to traverse a binary tree in Postorder traversal without recursion (solution)
37. How to Print all leaves of a binary search tree? (solution)
38. How to count a number of leaf nodes in a given binary tree? (solution)
39. How to perform a binary search in a given array? (solution)
Like an array, linked list, and string questions, I have also linked to all solutions for binary tree questions but you should only look at them once you have tried it yourself.
One trick I would like to share with you while solving tree questions is to remember that, similar to a linked list, the tree is also a recursive data structure and most of the tree based problems has an easy recursive solution.
For example, a subtree is also a tree which means you can apply the same steps to a subtree can devise a recursive solution. In the above list, many popular tree algorithms e.g. pre-order, post-order, in-order are implemented recursively as well as iterative.
If you don't feel confident to solve these problems and want to refresh your knowledge of binary tree and other data structure before attempting these questions, then you should check out Data Structures and Algorithms: Deep Dive Using Java from Udemy.

Top 95 Coding Interview Questions for Programmers
Here is my list of some of the most popular coding questions to crack any programming job interview.The questions are more like you find in the popular book Cracking the Coding Interview by Gayle Lakmann Mcdowell, one of the essential books to do well on a Job interview, but more focus on Data Structure and Coding rather than touching every single possible topic required for a programming job interview like SQL, UNIX, Database, Networking, etc, for that, you need to read books and you can find many good titles here.

1. Array-based Programming Interview Questions
If you ask me just one topic to prepare really well for coding interviews, I would pick the array. It's one of the essential data structures and favorite darling of coding interviews. There are so many popular coding interview questions that are based upon the array, some of them are easy and some are tough but you can be sure that you will see some questions based upon the array in your next programming job interview.If you don't know, an array is a data structure that holds other objects like String, int, float, etc. It holds them in a contiguous location in memory which makes them easily searchable and retrieval in O(1) time using the index.

2. String-based Coding Interview Questions
After array, String is the next popular topic on Programming job interviews, but if you have a good understanding of array then you can easily deal with String programming questions because String is nothing but a character array.The string is implemented differently in a different programming language like in C it's a NULL-terminated character array but in Java, it's an object. However, you can still get access to the underlying array to apply your logic.
Here is a list of some of the frequently asked coding questions which are based on String. Though some of them are quite old, you can still expect this in your programming job interview:

3. Linked list based Programming Interview Questions
Along with array and string, a linked list is another popular data structure in the programming world as well as on coding interviews. You will find a lot of questions on a linked list like reversing a linked list, adding a new element, removing an element from the middle, etc.It's also the counterpart of an array data structure. While array stores elements on contiguous memory locations, the linked list stores them at different locations and finds them by storing their address. a linked list is made of nodes, an internal data structure that holds the value as well as the address of the next node.

4. Binary Tree-based Coding Interview Questions
A tree is another popular data structure in the programming world and coding interviews. Unlike array and linked list, which are considered linear data structures, a tree is considered a hierarchical data structure and used to arrange information in hierarchical order.There are a lot of different types of trees e.g. a binary tree, binary search tree, AVL tree, Red-Black tree, etc but Binary tree and Binary search trees are also known as BST are two of the most popular ones and most of the questions are based upon them.
Some questions are also based upon theoretical knowledge of tree data structure e.g. finding the height of the tree, finding leaf nodes, checking if the tree is balanced or not, etc, hence you should also spend some time learning the basics, along with practicing coding questions.

Like previous topics, I have provided links to a solution but you should only look at them once you tried to solve the questions yourself. That's important for learning.
5. System Design Interview Questions
In last few years, System design and Software design questions have become an integral part of coding interviews. Either you will be asked a tough question like how to design WhatsApp or YouTube or asked theory questions like what is difference between load balancer and API gateway but you will get few questions on this topic.
Keeping that in mind, I am sharing popular System design questions for Programming and Software Engineering Job interviews. This contains both System design basics questions as well as System design problems from interviews:
76. What is Rate Limiter? How does it work? (answer)
77. How does Single Sign On (SSO) works? (answer)

Also, here is a nice diagram which shows high-level design of Instagram app from DesignGuru, one of my favorite place to prepare for System design interviews. Their Grokking the System Design Interview course is also the most popular resource for system design interviews.
And, if you need more System design interview resources for your preparation then you can also check this System Design Interview Prep Guide as well as best System design interview books, courses, cheat sheets, and websites.
That's all about some of the essential Programming and Coding Interview questions to crack any programming Job interview. This list covers the most important topics like an array, string, linked list, binary tree, and several others.
Once you have gone through all these coding questions, you can not only solve them when you see them in the interview but also develop the coding sense and problem-solving ability which will help you to solve new and slightly modified versions of these questions in real programming interviews.
Though, if you are not in a rush and want to hone your coding skill further, here are some more resources to practice questions

disappointing way to start an otherwise useful article: "hey guys..."
ReplyDeleteas a female SE, "hey guys..." feels like a careless and exclusionary introduction. if it was nestled into the body of the article, I probably wouldn't notice. However, as the first thing I read, my first thought is to comment, and then close immediately. no jokes here, I'm merely stating that I'm unlikely to be the only female engineer sensitive to this in the tech industry.
ReplyDeleteI say "hey guys..." in much the same way a southerner says "ya'll", it's just a plural for a group. Stop turning everything into a problem.
DeleteYeah, about time, I change my style and start saying "Hello all", thanks a lot.
DeleteSorry, I didn't mean that. It's just my casual way to start the article. I very much appreciate woman in tech and female software engineer. About time, I change my style to say "Hello All" instead of of "Hello Guys". Thanks
DeleteSorry, I didn't mean that. It's just my casual way to start the article. I very much appreciate woman in tech and female software engineer. About time, I change my style to say "Hello All" instead of of "Hello Guys". Thanks
ReplyDeleteHey feminist, it is just a word. Really you are going to get offended and discount everything that the page says because of one word? A real strong woman would move past it and realize the interview questions included within are actually quite good and detailed and probably will prepare you quite well for a job interview. Instead you are so concerned about the word "guys" at the top. Did you ever notice how actual guys don't spend time worrying about trivial things and just focus on getting the job done. Try that instead.
ReplyDeleteAll the lady engineers who get help from male engineers should remember to give back. Time and again, my experience with female engineers at conferences has been very poor. There is no sharing of knowledge. It cannot be one way street in the name of equality.
ReplyDeleteTwo, please respect the author who works for the whole community, rather than nit-picking over political correctness.
Three, have courage to post a comment like this with your own signature, not anonymously. :-)
Oh please, if you respected women in the industry, you wouldn't be so critical of them. I agree with the poster. The terminology should be more inclusive. It's a matter of respect.
Deleteomg, you fight each other just for "hello guys" words ?
ReplyDeleteVery useful..Thanks..!!
ReplyDeleteGood work..
ReplyDeleteThis is a great list of problems, but I believe readers should look elsewhere for correct solutions. I haven't opened all of them, but some of them (e.g. "remove duplicate chars from string", "find square root of a number") have some pretty bizarre solutions.
ReplyDeletefor square root I can understand but remove duplicate character from string seems straightforward, no?
ReplyDeleteMaybe you should "hello world" instead!
ReplyDeleteWow... I'm about 10 years into the developer job and not able to solve many of these question. Think I should quit my job :(
