Applied through university career fair. Got a phone interview scheduled in the next week. They asked thorough object oriented concepts and basic sorting questions. Also was asked 2-4 basic questions on tree traversal etc and told to explain the pseudo code. There was no actual coding involved anywhere. Got a call for onsite in 2 days. The onsite interview was pretty straight forward standard Factset approach. In the first round I was given a C++ code of linked list implementation and asked to find bugs. Some of the other people interviewd on same day were given Java code though. In the second round they asked me to design some card which I said I am not familiar with then they told me to choose any game of my choice. I choose Tetris and they asked to explain everything on board. I have previously prepared for Tetris game and studied the classes so I started explaining that then the manager changed the class design and told me to explain with the classes he described and use OOP concepts like inheritance, polymorphism etc. I did my best and explained all functionalities but I might have confused them a bit. In the third round they initially asked some UNIX commands questions and then asked to write code for a tree traversal question on board. And they asked to explain searching a dictionary. I explained it through Trie and they asked many more questions about Trie. I did well in this round. The interviewers told me that all technical questions were done for the day so I felt relaxed. Then a guy from my team took me to a restaurant for a lunch but continuously asked questions for next 1.5 hrs which I didnt really expect. He asked everything from Priority queues, AVL trees, distributed programming etc. I couldnt answer many questions here and I felt terrible. He is smart but also sounded very arrogant and was always belittling my previous company experience. I didnt even eat quarter of my lunch with him continuously asking questions. None of the other people on my day were asked any technical questions in the lunch though. Next round was with HR, which was basic feedback round and general questions. Last round was with the hiring director. He explained the job role which is mostly working on the DB and said it involves only about 30% programming and rest analyzing. I had a certification in DB2 in my resume so he went on asking questions about DB2, MySQL etc. I unintentionally didnt show much interest in this role and then he explained another role which is also work on DB but involves a bit more programming of 70%. At the end he asked me choose one of them, but i said I am fine with either of them(which is a big mistake). At the end there was talk with an executive along with all other interviewees. I got decision on the next working day and I didnt get the offer. I thought I performed well and was expecting they wouldnt consider the lunch interview. But I guess they did and it would have really impacted the decision. Also the final round with manager wasnt that good which might also have impacted. Overall I really liked the interview procedure and the hospitality of Factset. I am really disappointed that I couldnt get in although I performed well in most rounds. The only bad experience I had was the lunch interview from the member of the team.
