I applied through a recruiter. The process took 2 weeks. I interviewed at Fidelity Investments (Westlake, TX)
Interview
Sent my resume to one of the recruiters , got call the next day and she told she would submit the resume to the manager. the next day or so she called a scheduled phone interview. 4 one on one phone interviews. Next they invited me for in-person interview. Whoever interviewed me on phone were all there in the in-person interview.
In one or two days another recruiter called me and told the team was interested in my background and asked details abt my current visa status etc., He asked for few references and I gave two. The director contacted the references I gave.

1. DSA Round (Easy Level)
They usually don’t go very deep into complex algorithms. Expect fundamentals like:
Anagram check (e.g., compare two strings efficiently)
Palindrome check (string or number)
Basic array/string manipulation
Sometimes simple hashing or sorting logic
2. DBMS Basics
What is a primary key / foreign key
Difference between SQL joins (INNER, LEFT, RIGHT)
Basics of normalization
Simple query writing
They usually keep it conceptual + a few practical questions.
3. OOPs Concepts
Very standard questions, such as:
Pillars of OOP: Encapsulation, Inheritance, Polymorphism, Abstraction
Real-life examples
Difference between overloading vs overriding
Why OOP is useful
They may ask you to relate this to your project.
4. Puzzle / Logical Thinking
These are not super hard—just to test reasoning:
Basic math/logical puzzles
Pattern-based questions
Situational problem solving
5. Project Discussion
Explain your project clearly:
Problem statement
Your role
Tech stack
Be ready for:
“Why did you choose this approach?”
“What challenges did you face?”
“How would you improve it?”
