The first technical interview involved solving coding problems such as adding 1 to a number represented as an array and reversing a linked list in groups of size k. Additionally, candidates engaged in a detailed discussion on database management systems, specifically the concepts of normalization versus denormalization.

In the second technical interview, the focus shifted to networking and operating systems. Candidates were asked to illustrate the OSI model, differentiate between TCP and UDP, and solve coding problems like the Nuts and Bolts problem using the QuickSort partition function. There was also a focus on segmentation and paging in operating systems.

The third technical interview involved more coding challenges and database management questions. Candidates needed to swap a given node’s value with the preceding node in a linked list or convert a binary tree into an array-based representation, all without using the C++ standard library. This round also included standard HR questions to assess the candidate’s soft skills.
