Fidelity Investments Associate Software Engineer Developer interview questions

It was overall a very smooth interview process. The first round was the phone call from HR and they asked me more about my resume and what I do, some technical questions on computer science concepts like what is a stack vs heap. Then the interviewer moved me to onsite round at Fidelity and this was a 3 rounds 30 minutes each assessing the project work of the candidate, the overall fit and how the candidate is eager and excited to be on their team to learn and grow.

3 interviews: 1 with recruiter(behavioral), 2(one behavioral and one technical) Super nice, a previous college alumni showed me around the office, and spoke about the culture, career at fidelity. Then had my 2 interviews, back to back. They gave me the offer 3 days later
