Entrevista
I find a alumni to refer, they don't post intern job for graduate this year in my college's career fair. Monday is phone interview, basic question about Java data structure, ask about singleton and what kind of situation will there be more than one instance(multithread). Then Friday's super day. So tired in the final interview the interviewer seems very tired and speak in low volume.

Pregunta 1
Ask a lot about data structure and algorithm, questions are classical, 2sum, find head of cycling linked list, given access to middle node of a linked list and asked to be delete it. And OOD design a elevator system, and some SQL query, basically same as before, but I suggest you guys prepare for a SQL query that return the top node in a hierarchy structure, for example return the manager of the manager of the manager....until the boss, I am still not sure about that. And multithread concept and ATM question, producer/consumer question.

four back-to-back interviews 2 behavior 2 technical. Behavior was typical, technical asked some gotcha questions about data structures and OOP and afterwards some leetcode and asked some javascript questions and specific questions from experience on resume.

Interviewers were generally kind and welcoming, despite Superday being long. Interviews overall felt like conversations, although last interviewer did not give me a chance to ask any questions. Strong emphasis on aligning with their values, so definitely study those up. Some interviewers told me exactly which BlackRock values they were screening for.

Entrevista
Recently, I had the opportunity to interview with BlackRock for a technical role. The process consisted of two rounds – one technical and one managerial. Here’s a quick summary of my experience:
Round 1: Technical Interview
This round was focused on data structures, algorithms, and problem-solving. Some of the key questions I faced included:
Linked List: I was asked to implement and explain core operations and edge cases.
Spiral Matrix: A coding problem where I had to print a matrix in spiral order.
Binary Tree: Questions on traversal techniques and problem-solving using recursion and iteration.
SQL: Queries involving JOIN, GROUP BY, and handling real-time database scenarios.
Puzzles (from GeeksforGeeks): A couple of logic-based puzzles to test problem-solving skills and clarity of thought.
Overall, the interviewer was friendly and encouraged me to explain my thought process clearly.
Round 2: Managerial Interview
This was more of a techno-managerial discussion. The interviewer asked about:
My approach to solving problems when stuck.
How I would prioritize tasks in a high-pressure environment.
Some scenario-based problem-solving involving teamwork and deadlines.
A few follow-up questions on the coding round (like edge cases in linked list operations).
The focus was on communication, clarity, and decision-making rather than just coding.
Takeaways
Be thorough with data structures (Linked List, Trees, Matrices) and SQL basics.
Practice coding on platforms like LeetCode and GFG for puzzles and common problems.
Managerial rounds test your soft skills, ownership, and mindset just as much as your technical knowledge.
Overall, it was a great learning experience, and I found the interviewers very approachable and insightful.
