I have linked the solution but you should try to solve the problem before looking at the solution. Top 20 basic Algorithms interview questions for ProgrammersĪnyway, here is some of the frequently asked Searching and Sorting Algorithms questions from Interviews. Cormen to get an understanding of common Computer Science Algorithms like Searching, Sorting, Cryptography, Graph Algorithms and some common ones like Fourier Transform. On the other hand, if you like to read books or prefer books over online courses then you must read a comprehensive book like Introduction to Algorithms by Thomas H. That's just some common example and that's why practice matters a lot.ītw, if you are a complete beginner in the world of Data Structure and Algorithms, then I suggest you to first go through a comprehensive Algorithm course like Data Structures and Algorithms: Deep Dive Using Java on Udemy which will not only teach you basic data structure and algorithms but also how to use them on the real world and how to solve coding problems using them. Sometime, if you use a data structure like the one I have used in finding duplicate characters on String, they will ask you to solve that problem without using the Set data structure. It also makes you ready for any twisted questions and alternative problems like Interviewers often like to ask you to solve a particular coding problem using Recursion or Iteration. Practising these problems before interview not only makes you familiar with them but also gives you more confidence in explaining the solution to the interviewer, which plays a very important role in your selection. It's important that you practice these Algorithms based questions because even though they seem obvious and easy, sometimes they become tricky to solve in the actual interview, especially if you have never coded them by yourself. These are based upon common searching and sorting algorithms like String algorithms, binary search, graph algorithms, etc. I have blogged a lot about what you can find helpful articles in this blog but to recap let me tell you that apart from data structure questions, System Design Questions, and Programming language specific questions like Java, C++, or Scala, most of the programming job interviews also ask algorithm based questions. What is asked, what topics should you prepare, etc? You got to be prepared to grab that chance and for that, you must know that is expected from you on the interview. That's why you can't just take your chance lightly. You got to be lucky to get the call and make to the first round of interview, not just when you are a beginner but at any stage of your career.īut, Yes, it is the most difficult at the beginner level when you are searching for your first job. Hello All, If you are preparing for Programming job interviews or looking for a new job then you know that it's not an easy process.
