Facebook Interview | Set 1

I am a final year student of IIT Guwahati and the first phase of placements has just finished at our college. I was recruited by Directi but not before three grueling rounds of interview. I was also shortlisted by Microsoft, Facebook and Goldman Sachs as well but got rejected after the first round of interview from all the three companies :(. I will be posting questions relating to all the companies I was interviewed by as well as some interview preparation advice (which should be particularly useful for students sitting for on-campus placements). Following are Facebook interview questions Online Coding round: It boiled down to finding all possible simple paths (paths without cycles) between two vertices in a graph. Round 1: 1) Given a string, check if it is a palindrome by ignoring spaces. E.g. race car would be a palindrome. 2) Given two very large strings, consisting of only digits, multiply the two strings and return the result as a string. This article is compiled by Vikram Goyal. Many Many congratulations to Vikram for his selection in Directi. We will be soon publishing other interview experiences as separate posts.
