Hey everyone, so I recently reached out to the employees of Blinkit regarding consideration for the SDE1 position as they only hire through referrals.
The HR got back to me and said they have 3 rounds as part of the hiring process, each being eliminatory.
1st round is PS/DS.
2nd round is System Design.
3rd round is a Cultural Fit Call.

PS/DS Round

1. Write the code of postorder traversal without using recursion.
2. Leetcode problem - https://leetcode.com/problems/best-team-with-no-conflicts/

System Design Round

1. Design Whatsapp and follow up questions.
2. Write a sql query to find the nth maximum salary.
3. Difference between mutex and semaphore.

Unfortunately, I wasn't adequately prepared for the system design round, which led to my elimination. However, I would recommend thoroughly studying the relevant subjects for this round. Best of luck to those preparing for it!
