Experience:

This interview experience for a Software Engineer role at Western Digital (SanDisk) consisted of a coding test and two subsequent interview rounds.

Round 1: Coding Test: This was the initial screening round.

Round 2: Technical Round: This round covered various technical subjects.

• A sorting question, similar to the "Binary Array Sorting" problem, was asked.
• Projects mentioned in the resume were discussed in detail.
• Questions on DBMS and SQL queries, including join operations, were posed.
• If a project involved React, questions related to React were asked.

Round 3: Technical/HR: This final round included both technical concepts and behavioral aspects.

• Questions about Data Structures were asked, such as "Recursion uses what type of Data Structure?".
• Discussions on Binary Search Trees, including why they are better than linear data structures, and the conditions under which a binary search tree behaves like an array.
• AVL Search Trees were covered, specifically the need for their development.
• B+ Tree concepts were also part of the discussion.

A key tip for this interview process was to thoroughly review projects and have a strong understanding of DBMS and Tree data structures.
