BlackRock Interviews There were three rounds in total, one for math, two for coding, and three for 4×45 virtual onsite, which was of medium difficulty overall.
First round Math, late December
- xt+1 = a - xt + g - etwhere et obeys N(0,1), a what condition is satisfied that makes xt Answer: 0 < |a| < 1; xt What is the variance of the What is the vector form? Answer: g²/(1-a²), for vectors take the same var and solve the equation; for each xt According to σt What is the matrix form expression for performing the normalization? And what is the expression for the normalized time series model? Answer: y = L-¹ - x, x = L-¹ - y Substituting into the left end of the original equation simplifies to yt+1 Ready to go.
- Stability conditions for AR(2) models, conditions on CHARACTERISTIC VALUE, business loops.
- What is the expression for GBM, closed-form derivation procedure for call option price timing, how to use it in MC simulation.
- The first person to win 2 more games against an opponent wins the entire match, ask the probability of winning first.
- PDF, CDF, expectation, variance of Order statistics.
Second round of Coding, early January
Buying and selling stocks, anagrams, live data science project, no performance required, seconds.
Round 3 Virtual Onsite, late January
- Do you know what the risk factor of the Aladdin platform can be used for, and why choose BlackRock?
- MSE's flaw in timing modeling, answer: the coefficient of 1/n does not take into account the relative importance of high-vol/low-vol and temporal proximity.
- How to generate an N(0,1) from a U[0,1] and prove it? Answer: do inverse transform directly with CDF.(I said Box-Muller at the time, not the ideal answer.)
- Handpicked closed-form expressions for the B-S equation and binary option, see Greenback for details.
- Why do you want to work for BlackRock?
- Tell me something that's not on your resume (hobbies, interests, etc.).
- Tell me about a time when you showed a willingness to learn a new method or approach to solving a problem.

- Here at BlackRock, we are expecting someone with strong leadership skills to take this role. How would you describe your management style?
I haven't heard back since I finished the last round of interviews in late January, and I heard that there aren't many HCs that don't have sponsors this year. I have a very detailed Quant orientation timeline from beginning to end, and I hope that this experience will be of some help to those who are still looking for a job to go ashore.

After our strong interview assistance, OA ghostwriting, candidates through the analysis of these interview questions and communication, the interviewer not only understands the candidate's programming ability, but also see my clear thinking and effective communication skills in the problem solving process. These not only help to deal with a variety of interviews, but also enhance our ability to solve practical programming problems. I wish you all good luck in your interviews!
