I Software engineer scrivono i programmi per progettare e sviluppare software informatici. I colloqui sono prettamente tecnici, quindi preparati ad affrontare problemi di programmazione e rompicapi matematici. Le domande specifiche che ti saranno poste dipenderanno dal tipo di posizione che stai cercando nell'ambito della programmazione. Prova a fare le dovute ricerche su una disciplina software specifica, come lo sviluppo si siti web, di applicazioni o di sistemi.
First, a mathematic question, asking about a card game with how many possible way for the combination based on the rules it given. Second, let you to print out all the combination of 3 digit numbers with no duplicate, ex. 012, 013, ....123, 124, 125...
Implement a class that can calculate the running average of a stream of input numbers up to a maximum of N numbers.
Intersection of n sets without using a hash table.
Get numeric number out of a roman string, linear time Given: mapping I = 1, V = 5, X = 10, L = 50, C = 100, D = 500, M = 1000 Input/Output: II = 2, III = 3, IV = 4 VI, VII, VIII IX = 9 XL = 40, XLIX = 49
The initial question (writing a function to calculate a square root) ended up being the most difficult because it threw me off. I knew there was a good iterative method for doing so, but could not recall Newton's method in the moment, and I sadly let this nagging thought get in the way of my ability to work through the problem. My failure to perform well on that question set a negative tone for the rest of the interview, since each interviewer after the first can see notes from the previous interviewers.
Getting maximum and minimun number was not difficult but getting less than n comparison was tricky.
Implement a function to validate whether a given binary tree is a BST (i.e. write an isBST() function).
Given an integer set of numbers, print all the subsets. For some reason the interviewer asked to print the supersets, but what he means is subsets.
What is your dream job ?
Interviewer ask me to solve some permutation related problems. 1) Algorithm to get Index of a permutation when all permutations arranged in lexicographical order and its complexity
