Summary
I had an interview experience for an E4 role at Meta in London, covering multiple coding rounds and a system design interview. I am currently awaiting the results.
How it went
Screening Q1 given word 1 and word 2 return output baseball base : 4 landlord load : 0 hangover hanng : 4
Q2 minimum remove to make valid parenthesis
Full Loop:
Coding interview 1:
- course schedule
- given root, target k, print all nodes at kth distance from target node
Coding interview 2:
- given matrix, do diagonal traversal
- in sorted array find occurence of given word
System Design: Design auction in instagram.
Awaiting for res....

Minimum Remove to Make Valid Parentheses
Data Structures & Algorithms
Given a string s of '(', ')', and lowercase English characters. Your task is to remove the minimum number of parentheses ('(' or ')') so that the resulting parentheses string is valid and return any valid string.
- 03
Course Schedule
Data Structures & Algorithms
Given the total number of courses you have to take, numCourses, and a list of prerequisite pairs, prerequisites, determine if you can finish all courses. (Implicitly, if it's possible to take all courses without circular dependencies, or to return a valid course order).
