I applied through LinkedIn. Around ten days after, HR called me and scheduled the first round. One week later, the second round was scheduled. In between, I did not receive any feedback on whether I was selected or not. Approximately two weeks later, the third round was scheduled. Again, I was not aware whether I had qualified for the round or not.

After a couple of days, I got the mail for documentation and then received the offer.

First Round: Purely technical. Questions on SQL, ACID properties, joins, stored procedures, and performance.

• OOPs concepts
• Dependency injection

• Scenario-based questions on performance improvement

Second Round: US Managerial round.

Third Round: Tech and managerial. Questions on Agile, SQL vs. Mongo, and behavioral questions.
