These questions will not only help you to develop your problem-solving skills but also improve your knowledge of the array data structure. How are duplicates removed from an array without using any library? ( solution ).
Once you have gone through these questions, you should feel confident enough to attend any telephonic or face-to-face interviews.ītw, there is no point in attempting these questions if you don’t have sufficient knowledge of essential Data Structures and Algorithms or you have not touched them for ages. It’s not guaranteed that you will be asked these coding or data structure and algorithmic questions, but they will give you enough of an idea of the kinds of questions you can expect in a real programming job interview. The topic areas I’ve seen most often in interviews are array, linked list, string, binary tree, as well as questions from algorithms (like string algorithm, sorting algorithms like quicksort or radix sort, and other miscellaneous ones), and that’s what you will find in this article. I think it’s helpful to divide coding interview questions into different topic areas.
In this article, I’ll share some frequently asked programming interview questions from different interviews for programmers at different levels of experience, from people who have just graduated from college to programmers with one to two years of experience.Ĭoding 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 big organizations like Amazon, Microsoft, and Google and service-based companies like Infosys or Luxsoft, but many of them have no idea of what kind of programming interview questions to expect when you’re applying for a job with these companies.
