In this section, we’ll review the various interview questions that might be asked during a Software Engineer interview at Nasdaq. The interview process will likely assess both technical skills and behavioral competencies, so it's essential to prepare for a range of questions that cover your experience, problem-solving abilities, and technical knowledge.

Experience and Background

1. Can you walk us through your resume and highlight your most relevant experiences?

This question allows you to showcase your background and how it aligns with the role at Nasdaq.

How to Answer

Focus on the experiences that are most relevant to the position. Highlight specific projects, technologies, and skills that demonstrate your qualifications.

Example

“I have over five years of experience in software development, primarily focusing on Java and Python. In my last role at XYZ Corp, I led a team to develop a financial analytics tool that improved reporting efficiency by 30%. My experience with SQL and distributed systems also aligns well with the requirements of this position.”

2. What projects have you worked on, and how did you contribute to them?

This question assesses your hands-on experience and ability to work in a team.

How to Answer

Discuss specific projects, your role, and the impact of your contributions. Use metrics to quantify your success when possible.

Example

“I worked on a project to develop a real-time trading platform where I was responsible for the backend development using Java. My contributions included optimizing the database queries, which reduced the response time by 40%, significantly enhancing user experience.”

Technical Skills

3. What is your experience with SQL and how have you used it in your previous roles?

SQL proficiency is crucial for data manipulation and retrieval in many software engineering roles.

How to Answer

Discuss your familiarity with SQL, including specific tasks you’ve performed, such as writing complex queries or optimizing database performance.

4. Can you explain the differences between a linked list and an array?

This question tests your understanding of data structures, which is fundamental for software engineering.

How to Answer

Clearly articulate the differences in terms of memory allocation, access time, and use cases.

Example

“A linked list is a dynamic data structure that allows for efficient insertions and deletions, while an array has a fixed size and allows for faster access times due to contiguous memory allocation. I prefer linked lists when I need to frequently add or remove elements, while arrays are better for scenarios where quick access is essential.”
