I applied through another source.

• First technical round
• Second technical round
• Third HM round

All rounds featured only DS and Java questions. I solved standard DSA and Java questions. The HM was kind of rude. Prepare accordingly and solve standard BFS and DFS questions.

The first round featured a greater element than the target in a sorted array, which meant implementing upper_bound, and finding the nearest zero to one in a binary matrix using multisource BFS. There were good questions on runtime and compile-time polymorphism, string pool, and string literal.

• The second round covered the equilibrium index of an array where left sum equals right sum, a height-balanced binary tree, and the number of islands. It also included Core Java questions on static and polymorphism, basic Spring Boot questions, query parameters versus path variables, HATEOAS, and more.
• The third round involved a deep project discussion, scaling of applications, and a justification of the optimisation in past projects.
