In this section, we’ll review the various interview questions that might be asked during a Software Engineer interview at Lazard. The interview process will likely focus on a combination of technical skills, problem-solving abilities, and behavioral questions that assess your fit within the company culture. Be prepared to demonstrate your knowledge of algorithms, programming languages, and your understanding of the financial industry.

Technical Skills

1. Can you explain the difference between a stack and a queue?

Understanding data structures is fundamental for any software engineering role.

How to Answer

Discuss the definitions of both data structures, their use cases, and how they differ in terms of operations.

Example

“A stack is a Last In First Out (LIFO) structure where the last element added is the first to be removed, while a queue is a First In First Out (FIFO) structure where the first element added is the first to be removed. Stacks are often used in scenarios like function call management, while queues are used in scheduling tasks.”

2. How would you optimize a given algorithm?

This question tests your problem-solving skills and understanding of algorithm efficiency.

How to Answer

Explain the steps you would take to analyze the algorithm's time and space complexity, and discuss potential optimizations.

Example

“I would start by analyzing the algorithm's time complexity using Big O notation. Then, I would look for opportunities to reduce redundant calculations, perhaps by using memoization or by choosing a more efficient data structure that reduces lookup times.”

3. Describe a time you encountered a bug in your code. How did you resolve it?

This question assesses your debugging skills and approach to problem-solving.

How to Answer

Share a specific example, detailing the bug, your troubleshooting process, and the final resolution.

Example

“I once encountered a bug that caused a significant slowdown in our application. I used logging to identify the bottleneck, which turned out to be a nested loop that was processing data inefficiently. I refactored the code to use a hash map for faster lookups, which improved performance significantly.”

4. What is your experience with SQL and how would you use it in a project?

SQL is a critical skill for data management in software engineering roles.

How to Answer

Discuss your familiarity with SQL, including specific functions or queries you have used in past projects.

Example

“I have used SQL extensively to manage and query databases. For instance, in a recent project, I wrote complex JOIN queries to aggregate data from multiple tables, which allowed us to generate comprehensive reports for our stakeholders.”

5. Can you walk me through a project where you used Python?

This question evaluates your practical experience with programming languages.

How to Answer

Describe a specific project, your role, and the technologies you used, focusing on Python.

Example

“In my last project, I developed a web application using Python and Flask. I was responsible for building the backend API, which involved creating endpoints for data retrieval and manipulation. I also implemented unit tests to ensure code quality and reliability.”

4. Can you give an example of a time you worked in a team?

This question evaluates your teamwork and collaboration skills.

How to Answer

Describe a specific team project, your role, and how you contributed to the team’s success.

Example

“I worked on a team project to develop a mobile app. My role was to handle the front-end development. I collaborated closely with the designers to ensure the user interface was intuitive and user-friendly. Our teamwork resulted in a successful launch and positive user feedback.”

5. How do you handle feedback and criticism?

This question assesses your ability to accept and learn from feedback.

How to Answer

Discuss your approach to receiving feedback and how you use it for personal and professional growth.
