what are the most common coding interview questions? Here you go


The time has come to share the top 50 most common coding interview questions asked in interviews. These questions have been picked from different sources, like TopCoder, Glassdoor, Quora and just by my own experience.

I hope these questions will help you prepare for your next coding interview. These are the most popular so I decided to write a blog post about them.

A variety of questions can come up in coding interviews. From basic to more advanced.

Here is a list of the most common questions and how to solve them:

1. Reverse a String

2. Palindrome Check

3. Reverse an Integer

4. Max Character

5. FizzBuzz

6. Array Chunking

7. Anagram Check

8. Sentence Capitalization (Also, Letter Capitalization)

9. Printing Steps

10. Two Sum (Easy)

11. Binary Search (Easy)

Coding Town is a website that was built to help people interview for software engineering positions at top companies.

Coding Town is a free site that will help you prepare for your next interview by helping you practice and master the most common coding questions asked. In addition, they have a large list of coding interview questions from major tech companies.

On their website, they boast about having over 500+ questions and solutions to practice with as well as video solutions for over 100+ questions on their YouTube channel.

The best part about Coding Town is that it’s all free!

Coding is the process of translating programming code into machine language so that a machine can understand it.

The most common coding languages are HTML, Javascript, CSS, and SQL.

In order to learn how to code, you must first go to school for it or learn through online courses, and you must master one of the above coding languages.

Coding interviews are a part of the hiring process for many tech companies.

The objective of a coding interview is to test your programming skills by solving problems in a limited amount of time.

In this blog post, I will provide you with links to resources on common coding interview questions and answers.

1. What are some examples of coding interview questions?

2. How do I prepare for a coding interview?

3. What should I expect during a coding interview?

I am an ex-Google software engineer and the founder of Interview Cake. I created Interview Cake because I saw a lot of smart people who weren’t able to land jobs at Google and other top tech companies.

I was one of those people.

When I was getting ready to interview at Google, I spent months studying like crazy. But when it came time to actually do a practice interview, I couldn’t find any good questions to work on—so I ended up wasting a lot of time.

Practice makes perfect, so I wanted to work with real interview questions that had been asked at the most competitive companies. But those questions were hard to find! And once I did find them, they often weren’t explained very well.

So instead, I’d spend tons of time reading about tricky data structures or algorithms—without ever really learning how to use them in an interview!

I’d run into the same problem over and over again: how do you learn something if no one will tell you what it is?

The following problems are taken from the projects / assignments in the edX course Python for Data Science and the coursera course Applied Machine Learning in Python (UMich). Both of these classes are part of the Data Science MicroMasters that I am currently enrolled in.

I would highly recommend both of these courses. The assignments are interesting and the instruction is top-notch. There is no better way to learn than by doing.

If you are a student looking for additional practice or a job seeker looking for coding interview practice, you should definitely check out my repository of 200+ data structure and algorithm based coding interview questions.

The below problems all come from this repository. All answers use Python 3 syntax and will work on PyPy3 (often much faster than standard CPython), though they may be slower on PyPy if some features like type hints are used (which can’t be compiled away by PyPy).

1. Find the missing number in a string of numbers

2. Find the longest palindrome in a string

3. Find the longest sequence of consecutive numbers in an array

4. Find all pairs that equal to a given number

5. Remove all duplicates from an array

6. Reverse a string/number

7. Reverse each word in a sentence

8. Sort a string of words (alphabetically)

9. Print out the sum of two linked lists that are numbers (integers)

10. Write an algorithm to shuffle an array randomly
