Software Engineer Technical Interview Questions

Anmol R. - "The example given is wrong. The 2nd test case should have answer 3, as we can get to 6 by using 3 coins of denomination 2."See full answer

Luke P. - "A full stack developer could be summarized as the person who both writes the APIs and consumes the APIs. They are familiar with Databases/Data-layer services, middle-layer/application services and business logic, and finally familiar with the consumers whether front-end applications/UIs or other systems. They can understand the trade-offs up and down the stack, where to adjust along the service-call-path. Ideally they are comfortable programming both async calls (front end javascript promises, e"See full answer

Vishal T. - "Go has simpler syntax than Java. It is light weight. It is not Object Oriented. It does not support function overloading and function overriding. But these are small technical differences. Both are similar when it comes to testing. You have to create a mock object and implement an interface. Functionally, I did not feel any major difference."See full answer

Shivam S. - "Binary search is the technique to search an element in a sorted array in O(log(N)) time. It is also used in problems wherever we find monotonically increasing or decreasing patterns."See full answer

Anonymous Dingo - "Here’s a commonly used Git branching and release strategy that we used at my previous role: Branching strategy (Git-based) a. Main Branches main: Production-ready branch.

Praful B. - " The productofarrays() function works by first creating an empty array to store the product of the two integers. Then, it iterates through the first array and multiplies each element by each element in the second array. The product of each element is then appended to the product array. Finally, the product array is returned def productofarrays(array1, array2): """ Calculates the product of two integers represented by two arrays. Args: array1: The first array. array2: The se"See full answer

Mourya C. - "I try to solve this initially using quick select where will take a pivot element and position the remaining elements and check if the current index is answer or not and continue the same but it requires o(n*n), but interviewee is expecting the best from me, so at the end i tried solving using heaps where will check the difference between k and n-k to use min or max heap after that we will heap the array, and will keep popping the element k-1 and return the peek one which leads to answer."See full answer

Luca D. - "Classes are represented in memory as areas where code and class shared objects are. The JVM use class loader to load classes and unload them if no more required at runtime as specified at https://docs.oracle.com/javase/specs/jls/se8/html/jls-12.html#jls-12.7, to name a very consolidated version of JVM. The interviewers supposed memory was freed without being subject to GC. I asked to discuss to clarify which hypothesis is right, the interviewers dismissed me. I'm very happy they didn't select m"See full answer
