Round 1 – Technical Interview

Introduction

• The interviewer asked me to give a detailed self-introduction.
• I shared my academic background, skills, and projects.

Project Discussion

• I discussed my project where I had implemented JWT (JSON Web Token) authentication.
• The interviewer asked me to deep dive into the concept of JWT.
• I explained the JWT structure (Header, Payload, Signature), how it works in authentication/authorization, and why it is widely used.
• He was satisfied with my explanation and moved to the next question.

SQL Queries

• Query 1: Find the average salary department-wise.

• Query 2: Find the second maximum salary in the table.

  • First, I explained how to find the maximum salary.
  • Then I gave two approaches for the second maximum salary:
    • Using LIMIT
    • Using a subquery (MAX with a condition < (SELECT MAX(...)))

• Follow-up Query: Find the average salary department-wise, but only for salaries less than the second maximum salary.

  • I explained the filtering logic using a subquery.

C++ Implementation

• Finally, the interviewer asked me to implement the last SQL query in C++.
• I discussed my approach using pairs (to store department and salary) and sorting (to calculate averages efficiently).
