Fidelity Investments interview questions

very easy interview process, had a basic call with HR just to get to know me. then interviewed on site a few weeks later, got a call a week after that that i got the job. all behavioral questions, was very laid back

I interviewed twice with them with both times being ghosted. Last year interviews was different then this year. Last year was 2 interviews. The recruiter call and technical interview that seems to have varied from person to person. I got asked UML/OOP (animals in a zoo), SQL (inner join), reverse a linked list, and make a real-time clock with JavaScript. No behavioral. The interviewer was drilling with in depth questions. This year interview consisted of 3 interviews. A recruiter call, 30min behavioral, and 30min technical, Behavioral and technical were on the same day after each other with different interviewers on site. Behavioral did involve talking about technical concepts as well. For the technical, there was no laptops or whiteboards to solve the coding problem. I got asked how I would find the first non duplicate character in a string. The rest of the interview was technical concepts that weren't directly involved with tech stack of the role. It was like "how do you maintain your code?", "how do you find a bug that happens infrequently?", "how do you go about understanding a codebase that has no documentation?", etc. Barely any OOP, SQL, Java, questions. For both I was told by the recruiters to wait a week to hear back with results. Both times I was ghosted. No message, email, or phone call. The least a company you've invested time with could do is give you a response back. Everyone was really nice and helpful. However, very unprofessional and disappointed with the ghosting.
