Hacker rank || OA

I got the opportunity for OA round through refferal.

The round took place on hacker rank platform,

The OA round consists of MCQs , SQL query , DSA problem.

There was total

• 2 SQL queries (difficulty - medium)
• 10 mcqs ( medium to hard)
• 2 dsa (difficulty - hard)

DSA questions was on graph (both)
sql query can be solved easily
mcqs - eg :(expected output for the code snippet)

This was all about OA round

Verdict : Qualified

Will update about the second round. Hope this will help for the preparation.
