OA contains 5 math problems. The phone interview is quite hard, about probability and algorithm. I think after the phone interview and there will be a virtual onsite as well. Unfortunately, I cannot pass the phone interview.

Question 1
1. gamble game with 0.6 probability to win and choose the best policy; 2. there are n points on the plane and then find three points to form the largest angle.
The interview process involves a couple of online assessments and once you pass those there is the technical screen after the final interview. The technical screen involves probability, statistics questions that are quite hard - but which is expected for a quant researcher (greenbook like questions)

Question 1
One question I parrticularly remember was to calculate EV of 2 games with a box in each. One game has a box with 100 notes that give +1 and a note that gives -100. The other game has a box with 100 notes that give -100 and a note that gives +100. You have to calculate EV of each game and choose which one to play and why

HackerRank Coding Test (3 problems, leetcode medium level), then Vidcruiter Test (need to verbally explain, serveral math, 5 min each), then Technical Phone Screen (normal brain teasers, probability etc.), then final round.
Questions d'entretien [1]
Question 1
Problem Analysis:
A k-star consists of a center node and up to k arms (edges to other nodes)
We need to find the k-star with maximum sum of all its nodes
For each potential center, we choose the best neighbors (up to k) to maximize sum
Algorithm:
Build an adjacency list from the edges
For each node as a potential center:
Get all its neighbors
Sort neighbors by their values (descending)
Select up to k best neighbors
Calculate sum: center + selected neighbors
Return the maximum sum found

the first step is a leetcode like challenge, easy to medium difficulties. for 2 hour, there is enough time for you to solve them. if you pass the test cases, the following is the video math OA
