I applied in-person. The process took 1 week.

• Round 1: DS and Algo round. At the start, the interviewer gave some intro about the company and himself. Later, he asked about projects, and then he started Algo questions.
• Round 2: Technical round.
• Round 3: Fitment round.

• Round 1: DS and Algo round. At the start, the interviewer gave some introduction about the company and himself. Later, he asked for projects, and then he started Algo questions. Q1) Maximize the sum of nodes in a binary tree, where we cannot select nodes that are directly connected with an edge. We have to return the maximum sum. Q2) Given a string consisting of only 0's and 1's. Find the minimum swaps required to convert the string such that all 1's should be together (not necessarily at the beginning or end).
• Round 2: Technical round. After the introduction, he started with projects, then basic questions related to OOPs such as polymorphism, abstraction, inheritance, etc. Then there were questions related to SQL based on indexing, and NoSQL basics on how it functions. Then he asked about the questions being discussed in Round 1, along with the approach I used to solve them. Then he asked me to implement an LRU cache in the language of your choice (prefer Java). The interviewer was very friendly, and he helped me to solve that.
• Round 3: Fitment round. This round was with the manager. There were some questions related to my past projects, then questions on Spring and SQL.
