Nagarro was in our campus for placement drive. They took written test in the campus and called the shortlisted candidated to their branch at Gurgaon. Written test consisted the 10th standard mathematical questions like geometry, trigonometry etc. Also, it had some aptitude questions, which were easy comparatively. Written test also had the C-programming basic questions, which were not much difficult for any computer engineer to solve. then, there were coding test, followed by technical interview and HR interview. Coding Test- 1. Check if binary conversion of given number is palindrome or not. eg. 843 is palindrome. 2. Separate 0's and 1's in that order from a array of only 0's and 1's. 3. One Sentence (string) is given. find out the words, that has length even and greater than equal to 4 (e.g. 4,6,8.. etc.) and separate them with space. e.g. Given String : "abcd abc abcde abcdef" Output: "ab cd abc abcde abc def" Technical Interview- He asked me to explain the code I had written in the coding round. then asked algorithm of following- How will you rotate the contents of matrix (nXn) in-place clockwise (remember we need to change the contents of the matrix, not just print the element in that order).
