The hiring process is simple and elegant and starts off with one or two telephonic interviews. The telephonic interview is more or less there to gauge your interests, FactSet is trying to expand their product and they are doing both great back-end and front-end work and they want to assess what position is a fit for the candidate being interviewed. Apart from gauging the interests there would be some technical questions so that they know they aren't interviewing a moron. I was asked the following questions during my telephonic interview -: Q1) Explain how Hashing works? Q2) What are some collision resolution techniques used to uniformly distribute the keys in a hash table? Q3) They gave me some scrabble game and asked me 5 data structures that could solve the problem and I also had to mention the time and space complexities required to solve the problem. I was called to their headquarters in Norwalk to move further in their process and there are 5 additional interviews that are held onsite -: Round-1 Once you reach, you will be give a demonstration of their awesome product. Don't undermine this step listen to the demonstration carefully as here you can pick up some questions that you can talk about in your lunch interview. Round-2 - Debugging Round In this round you will be given a C/C++/Java code based on your language of choice and you will have to spot maximum errors in the code and suggest solutions to optimize the code. Look out for memory leaks mostly, if you can spot them all I think you have passed the round. All of the errors need to be spotted within 10 minutes and the code base given is 6 pages long, be sure to maintain your pace because in the rest 35 minutes you will be talking about the mistakes you pointed out. Round-3 - Algorithms Round In this round they will ask you algorithmic questions to test your logic and in some cases they might as well ask you a brain teaser. The questions I was asked were based on finding Lowest Common Ancestors in Binary Search Tree, Reversing a linked list both recursively and iteratively, given a pre-order and in-order traversal of the BST reconstruct the BST and question on strings and hashtable again. They will ask you to write the code on whiteboard make sure you do as few mistakes as you can. Round-4 - Design Interview This round started in a rather unconventional manner I should say. I was first tested on my advanced C++ knowledge regarding namespaces and a bit of STL and then was given a code snippet that dealt with virtual functions and inheritance and then he moved onto the design aspect of the interview wherein the focus was to test my understanding of designing a big system both from entity point of view and testing my knowledge of inheritance and design patterns. Round-5 - Lunch In the lunch you will be taken out to a restaurant(it was a good one) and there you can talk to the managers and get a sense of what's it like to work at FactSet. Round-6,7 - HR All in all, it was a great experience interviewing with FactSet, would definitely recommend everyone applying here. The accomodation given was great and they handled all my expenses gracefully.
