I applied through college or university. I interviewed at Fidelity Investments (Mangaluru) in Aug 2017
Interview
There were four round of interview,1st-written test,2nd and 3rd technical interview,4th hr interview
Round I
This round was 60 multiple choice questions(20-general aptitude, 20-technical, 20-again technical(based on either communication/electronics/computer science)).Technical was a bit easy and aptitude took time to solve.
Interview questions [2]
Question 1
Round II(F2F-technical)
They shortlisted around 60 students for the second round. Second round was technical F2F. I was lucky to have a panel member from ECE and he didn’t know much about Data Structures(I’m from IT :-P). So, he asked some basic datastructure questions:
Name any some of the data structures you know – I told linked lists, stacks, queues and trees, etc
He started with Linked list and asked code for reversal of linked list
Deleting a particular node in a Circular Linked List
Binary Search logic and its code
Any other search algorithms he asked and I said Linear search, etc
Time complexity comparision of different search algorithms
Then, he moved onto Trees
What is balancing of a tree?How to do it?
What is AVL tree?(He asked to explain and made me to balance an AVL tree as well as write a code for it)
Types of trees.
C/C++:
First question was how do you rate your knowledge in C/C++?- I told 8-9 out of 10.So, he started asking.
Difference between Macro and Inline?
What is the new thing you learned about C/C++? (I told him how to calculate sizeof without using sizeof() operator)
What’s the silliest mistake you’ve done and after recognising the mistake, you thought as ohh !!! this simple mistake I made??
Structure Padding question:
struct temp{int a ;char b;int c;}
What is the sizeof this structure?Answer:12(not 9 because of structure padding)
It was a good experience
Nice managers
Tough questions
Mainframe related
Work related questions
About previous company
There were 4 rounds
HR Manager Technical and telephonic
All rounds were good and exceptional
Managers were good
Had exceptional knowledge
Leads were good
Had indepth knowledge on the system and processes happening and general IT industry trends
I applied online. I interviewed at Fidelity Investments (Boston, MA) in May 2017
Interview
30 minute phone call with a recruiter, 30 minute phone call with the hiring manager, and about a 2 hour onsite composed of four 1 on 1 interviews with the hiring manager and 3 engineer/architect/director.
The phone calls were pretty much the standard behavioral questions like why Fidelity Investments, tell me about yourself, what you'd like to do, etc.
The onsite interviews were most behavioral questions, but there was 1 "technical" round. The technical round wasn't based on problem solving, data structures, algorithms, team work or any of the standard technical interviews you'd expect. It was just a bunch of questions on specific parts of technologies and the expectation was that you would be able to read the interviewers mind and respond with the exact answer in his head. Other than the "technical" round, the other interviewers went pretty well; the interviewers were friendly and the conversations were good.

Question 1
Unfortunately, I do not remember any of the specific questions asked in the"technical" round. They were a bit ridiculous. No SQL/databse, data structure, algorithm, concurrency, programming language specific, etc related questions.
