Fidelity Investments Full stack developer intern interview questions

First round: Call with recruiter, asked basic questions about myself + experience. Second round: Technical interview, asked basic OOP design questions and coding questions (equivalent to LC easies). Overall a great experience.

I was referred and submitted my application through a referral link. There was a phone interview that asked me about my general knowledge and the 4 OOP principles. Then I had a coding interview that was extremely simple and just involved psuedo-coding a few classes. My return offer interview had a few basic questions (reverse a string, find a palindrome) and a few SQL questions.
