Flipkart Interview | Set 16

• 1st round ( machine coding round)
  Write down code in any language for a simple employee hierarchy which has 3 types of employees.
  1. CEO
  2. Manager
  3. Employee

  where an employee can have only 1 mgr, and a mgr has 1+ employees.

  
  
  

  We were asked to input employee details(name, id, salary, rating etc) in any order (employees might be input before his manager), create the hierarchy and implement these functionalities:

  1. Print hierarchy given any employee/mgr/CEO (used an n-ary tree + hash table)
  2. Given a bonus and performance rating of each employee divide it to the lowest level employees(in the hierarchy ) in the ratio of their rating. i.e 100 divided among 2:3 is 40 and 60. and print the bonus of each ( simple recursive solution)
  3. Top 10 employees with ratio of bonus:salary (used maxheap)

  Write working code, modular, extensible, corner case handling etc. was around 1.5 – 2 hrs

  
  
  
• 2^nd round
  discussion on your solution of the 1st round, how can you optimize it, then a review of the written code
• 3^rd round
  DS and ALGO
  1. Snakes and ladders problem
  2. Median in a stream of integers
  3. string searching (KMP / suffix tree was needed: not code just the logic)
  4. Given any language, you use libraries, which might use more lib etc. Find the order of building the libraries (Topological sort)
  5. Given a server with a stack with some initial state say 1 User can modify the stack using regular ops eg push 2, pop etc and each op causes a version change. i.e version 1 : 1 , version 2 : 2,1 , version 3 : 3,2,1 , version 4 : 2,

  You have to design it s.t. person can ask for any version of the stack (keep copies every k times and keep the ops in nonvolatile memory)

• 4^th round
  • Design a new kind of an online poker game
  • Give all entities and relationships in depth
  • Further in-depth discussion of how to make it more HA friendly, how to
  • Handle players crashing etc
• 5^th round
  • HM round
  • In-depth discussion of projects and general questions eg when you disagreed with your mgr etc

  The process was crisp and took place from 10 AM – 5 PM on a weekend in Bangalore
