Summary
I interviewed for an E5 position at Meta in London, completing a screening round and an on-site consisting of coding, design, and behavioral rounds, but ultimately received a rejection.
How it went
Screening Round
Q1: Given departure and return flight ticket price in two seprate array for each day. Give minimum cost round trip
Q2: Get Max K element in un sorted array
On Site: Coding 1: Q1: find closest element in BST
Q2: product of two sparse array like more zeros then non zero number optimal storage of array then extention of one long and other short array
Coding2: Q1: Left view and then right view of tree in response second question forgot
Design round:
Design Top K songs per user for past 90 days Messed it up big time by having two pointer approach from hellointerview.
Behavioural round:
- project proud of
- conflict handling
- building systenm with unclear requirement
- How you are improving yourself continuosly
- handling conflict in product discussion
- difficult work environment how did you manage.
I can't imagine i messed it up this process.

- 01
Minimum Cost Round Trip Flights
Data Structures & Algorithms
Given departure and return flight ticket price in two separate arrays for each day, find the minimum cost for a round trip.
- 02
Find Kth Largest Element in Unsorted Array
Data Structures & Algorithms
Get Max K element in un sorted array.
