MCQ( 20 qns includes Quants, logical, histogram, Maths(log)) Problem solving: 1) Race Winner Problem(Greedy) You are given an integer n representing the number of racers and an array a[] where a[i] is the current score of the i-th racer. In a final race: The 1st place finisher gets n points 2nd place gets n-1 points … Last place gets 1 point Each racer can finish in any position. Question: How many racers can still win (i.e., can end up with the highest total score after the final race)? 2) SQL Query Problem You are given a table Project and Dept with the following columns: dept rating date (format: MM/DD/YYYY) Question: Write an SQL query (in SQLite) to retrieve all departments that did not have any project with rating = 4 between the years 2012 and 2015 (inclusive). 3) Pretty Pair of Quadruplets(DP) You are given two arrays A[] and B[], each of size N. A quadruplet of indices (i1, j1, k1, l1) from array A and (i2, j2, k2, l2) from array B is called a pretty pair of quadruplets if: 1 ≤ i1 < j1 < k1 < l1 ≤ N 1 ≤ i2 < j2 < k2 < l2 ≤ N A[i1] = B[i2] A[j1] = B[j2] A[k1] = B[k2] A[l1] = B[l2] Question: Find the total number of possible pretty pairs of quadruplets. 4. Remove duplicates using numpy or pandas (ML no java or any other lang allowed)

Purely on technical basic snowflake related questions and managerial sql based questions and python but they used google meet instead of teams little bit confusion is there, and interview was smooth and clean
