How to clear coding online test
Most firms use coding online tests to assess applicants' problem-solving and coding abilities. The purpose of the coding online test is to identify candidates who may do well in the onsite interview. These coding online tests are held on platforms such as HackerEarth, where programmers from all over the world compete for attractive prizes and, occasionally, job offers from big software organisations. To ace these tests, you must be well-versed in data structures and algorithms.
In these coding online tests, most major programming languages are supported for the online coding exam. They provide you with an easy-to-go coding environment, where you can write, debug, and execute your program. In an coding online test, you will be given multiple programming-based problems. These problems will state the input and output format and the constraints that the program had to follow. The program written by you will be tested on various test cases and maybe also on some hidden test cases as well.
To prepare for the coding online test, the first thing that you need to do is to prepare all the previously asked questions from that particular company. You can easily find them on the Coding Ninjas Portal. There was a high chance that there would be repeated questions.
Another tip would be to regularly practice on competitive programming websites like Leetcode. Participate in their contests. It’ll help you solve a question in a time-bound manner.
For example, the Amazon online assessment test is administered on a variety of platforms and consists of 3-4 questions of simple to medium complexity. In most on-campus hirings, Amazon online assessment test includes a coding round in addition to aptitude and psychometric tests.
The Amazon online assessment test includes the following important topics:
=> Number Theory
- This includes basic number theory problems, even starting from GCD, LCM, modulo operations, Fermat’s theorem, etc.
- You can also follow some number theory problems from Coding Ninjas Course for learning in-depth about these concepts.
=> Greedy Algorithm
=> Binary Search
=> Dynamic Programming
=> Divide and Conquer
=> Hash tables, maps
=> Trees, BST
=> Graph algorithms like DFS, BFS, Dijkstra
Let's take a look at how to prepare for examinations like the Amazon online assessment test. Brush up on fundamental data structures such as the Stack, Linked List, Queue, Heap, Binary Search Trees, Hash Tables, and Graphs.
The most frequently asked questions in the test are on sorting and searching. Refresh your memory on Merge Sort, Quick Sort, Heap Sort, and Binary Search. Tree traversals are also essential. Learn about DFS and BFS. Pre-order, in-order, and post-order traversal models are all covered. Examine the Prim and Dijkstra algorithms for graph traversal. Read about Divide and Conquer as well as Dynamic Programming.
=> Prepare for 3-4 months by practicing problems from Leetcode, Coding Ninjas' Code Studio, Interview Bit, gfg, and other sites. Also, learn how to optimize your code.
=> Know Your Basics: Thoroughly understand the fundamentals of data structures and algorithms. You don't want to squander time at the last minute Googling how to execute a deep copy. Learn the fundamentals and keep practicing. Complete as many prior amazon online assessment test code tasks as you can.
=> Participate in online forums, You should go through several discussion boards to learn about different problem-solving approaches. It broadens your knowledge and sharpens your creative abilities.
=> The key is practice. Do as many practice questions as you can. Several online websites (such as Leetcode) offer hundreds of practice algorithmic questions. Make the most of them.
=> Nowadays, the questions in coding online tests are more difficult than regular programming questions. Therefore, it's critical not to rely just on standard questions; instead, try a variety of questions to assess your problem-solving abilities.
=> You must be consistent. Therefore, start practicing by giving Leetcode contests that imitate a very comparable atmosphere and questions to give you a feel for a true coding online test. Although it may seem apparent, honing your coding abilities is the greatest method to keep them fresh. Work on tackling difficult code problems. Develop new ideas and enhance your coding to generate the most efficient and elegant code possible. To practice, use online coding websites.
=> It is critical to be conversant with the coding platforms. Most coding IDEs are quite similar, and practicing in any of them will give you a good understanding of the process. Begin by experimenting with data structures and algorithms from popular websites.
=> The code's time/memory complexity is frequently asked. Learn how to compute it. Also, keep in mind the temporal complexity of traditional methods.
=> Make an effort to give an ideal solution and ensure that your code is understandable. Having 60% completed code for the ideal answer is preferable to having 100% functioning code for the difficult solution.
=> Coding online tests come with written instructions, so read them well and take your time before beginning. Take your time. Keep track of the time, but don't overlook vital things.
=> It is possible that you attempted to complete several questions on Leetcode but still struggled to pass an coding online test. This is frequent, but the key point is to understand the fundamentals and keep practicing.
=> If you're running out of time, prioritize the algorithm's most crucial parts. For example, if you are going to construct a sort, you should prioritize the Comparator because it will be crucial to the program's logic. To stand a chance of passing the interview, you should have something to present for both questions.
Regardless of how stressed you are, try to relax and get a full night's sleep to put yourself in peak condition for your coding online test. Take the coding exam seriously, but don't become overwhelmed or stressed: Always be modest, open-minded, and kind. Remember that your interviewers are also individuals who want the best for you.
Coding exams are designed to assess your technical abilities as an engineering applicant. It allows engineering managers to assess your technical proficiency. As a result, whether you pass or fail the interview is not necessarily determined by the outcomes of your coding exam.
Tech businesses like candidates who are well-prepared and can strike the ground running. Code tests like the amazon online assessment test are an excellent standard by which they may judge you.
