Round 1: 6 OA problems 40 minutes which had probability and linear algebra. Being familiar with matrix manipulation, Poisson PDF, recursion relations is more than enough. Round 2: 30 min CV review and motivation as to why QR rather than doing research in academia. Next 30 minutes: 4 probability/brain-teaser/linear algebra/market making. The probability/brainteaser problems are of style that are seen in dynamic programming i.e. recursive relation but no live coding was asked.
(1st round HR) What do you know about our company?
There were alphas that we had to make
What is the minimal natural number that ends with digit 4 such that moving its last digit to the first position (i.e. 1234 => 4123) increases it exactly fourfold? Answer:___
C questions (1h): mainly guess what will the ouput of some code C++ questions (1h): questions about the phylosophy of C++ Quant questions (2h If I remember well): typical but you have between 3-5 min for each problems ! You need to be well trained (like you just finish university)
Steps tetrahedron, expectations
Derive formula for linear regression
Triangle ABC has sides of length 45, 60 and 75. A point X is placed randomly and uniformly inside the triangle. What is the expected value of the sum of perpendicular distance from point X to this triangle’s three sides
The expectation of rolling the dice and get 2 consecutive 6
Tell us what we do? What is the position?
