First-hand accounts from people who interviewed at BlackRock.
Investment Analyst
The interview process was really challenging and intense. It felt rigorous, technical, and demanding, requiring precise and analytical thinking under high pressure. It was competitive, thorough, and focused on problem-solving and strategic thinking. The whole thing was very detailed, fast-paced, and stressful. They presented complex, time-constrained problems to test critical-thinking, logical reasoning, and quantitative skills. It was also behavioral and scenario-based, definitely tough, comprehensive, and grueling. The evaluation was exacting and nerve-wracking.
No confirmed questions were included in this interview report.
Software Engineer
There was no HR interview, only a technical interview. The interviewers were really shy and if they asked a question, they wouldn't follow up. For example, I said if I sort string characters, then make a string, then check the hash to see if they are anagrams. They asked me what I meant by hash. Like, what I meant by hash. I started talking about hash and how it functions in Java. After that, there was awkward silence. Without any follow-ups, like it was correct or not.
- There was only a technical interview, no HR. The technical interview involved LeetCode tasks. One task was to determine if a triangle has two equal sides or three equal sides.
- Another task was to identify anagrams within an array of strings and store only the first encountered anagram in a list.
- The candidate inquired if streams could be utilized for this task.
Software Engineer
I had an interview with a software engineer from the Aladdin Engineering Team. He first introduced himself and the team, then asked me to introduce myself. After that, there were 7 comprehensive questions. The first 5 were behavioral, and the last two were scenario-based. The interviewer was very nice and friendly, asking some simple follow-up questions after my answers. The whole process felt like a casual conversation with a friend.
- Can you share an instance where you made an error during a presentation?
- Regarding your project, could you elaborate on the specific tasks, meeting frequency, team roles, overall project timeline, and expected completion date?
- What would you consider your greatest weakness?
Quantitative Director
The interview panel seemed immature; I'm not sure how these people hold Director positions. The first round was a coding round where the interviewer was inflexible, only accepting the solution they had in mind. They weren't open to alternative valid approaches. I asked them some logical questions, like whether a table could realistically have a million columns, and if adding parallelization techniques for 10,000 sequential loop items would be excessive.
- How would you un-pivot a table from columns to rows?
- Is it realistic to have a table with a million columns?
- Is it worth using parallelization for a sequential loop of 10,000 items?
