Last Updated : 5 Aug, 2026

Candidate Information:

  • Status: Employed
  • Experience: Fresher with prior internship experience in software development
  • Target Position: Student Intern
  • Location: Kolkata, West Bengal, India

Overview of Interview Process:

  • The interview process consisted of an initial screening followed by three technical interview rounds. The entire process primarily evaluated problem-solving ability, programming fundamentals, and knowledge of core computer science subjects.

Initial Screening

  • Applied through a referral.
  • Submitted my resume.
  • Received a call after my profile was shortlisted.
  • Discussed my background, technical skills, and projects.
  • The recruiter explained the interview process and scheduled an offline interview.

Technical Round 1

  • Duration: Approximately 1 hour

The first round focused mainly on Data Structures & Algorithms and C/C++ fundamentals.

Some of the questions included:

  • Write a program to find the mirror image of a binary tree.
  • Explain dynamic memory allocation in C and C++.
  • How would you dynamically allocate memory for 1D, 2D, and 3D arrays?
  • Follow-up questions related to pointers, memory management, and C++ concepts.

Technical Round 2

  • Duration: Approximately 1 hour

Some of the questions included:

  • Implement the functionality of the strtok() function in C.
  • Given a set of instructions with dependencies, determine a valid execution order.
  • Identify an efficient algorithm and data structure to solve the problem.
  • Implement the solution after explaining the approach.

Technical Round 3

  • Duration: Approximately 1 hour

The final round covered algorithms along with core computer science concepts.

Some of the questions included:

  • Solve a problem using Binary Search after first explaining the brute-force solution.
  • A graph-based problem where I had to identify edge cases and explain how my solution would handle them.
  • Questions from Operating Systems.
  • Pointer-related questions in C/C++.

The discussion emphasized optimization, correctness, and handling edge cases.

Post-Interview Reflections:

Company Culture: The interviewers were friendly and encouraged discussion throughout the interview. They focused on understanding how I approached problems instead of expecting immediate answers.

Work Environment: The interview process was well organized. The overall environment felt collaborative.

What the Interviewers Focused On

  • Problem-solving skills
  • Strong understanding of C/C++ fundamentals
  • Data Structures and Algorithms
  • Operating Systems basics
  • Ability to optimize solutions
  • Clear communication and logical thinking

Interview Result:

  • A few days after the interview, I received the selection result and was offered the internship.
  • After successfully completing the internship and receiving positive performance feedback, I was also offered a full-time position.

Closing Note:

Tips for Future Candidates

  • Build a strong foundation in C/C++.
  • Practice Data Structures and Algorithms regularly.
  • Revise pointers, dynamic memory allocation, and Operating System fundamentals.
  • Be comfortable explaining both brute-force and optimized approaches.
  • Having a basic understanding of Verilog and SystemVerilog will be an added advantage.
