Once I fix the issue, I’ll rerun the tests until they meet all of the requirements.”

Provide an example of a time when you had to troubleshoot a database issue and explain your process.

This question is an opportunity to show your problem-solving skills and ability to work independently. When answering this question, it can be helpful to describe the steps you took to troubleshoot the issue and how you solved it.

Example: “In my last role as a senior database developer, I had to troubleshoot a major issue with one of our databases that was causing some of our applications to crash. After speaking with my team about what they were experiencing, I began looking at the server logs to see if there were any errors or warnings. From there, I used debugging tools to check for any issues in the code. Ultimately, I found that there was a bug in the application’s coding that needed to be fixed.”

If hired, what would be your approach to learning about the needs of our company?

This question helps the interviewer understand how you plan to integrate into your new company and culture. Your answer should show that you are willing to learn about the organization’s goals, values and processes. You can also mention any specific research methods or tools you would use to gather information.

Example: “I would start by meeting with my manager to discuss their expectations for me as a developer.

I would also ask my colleagues if they have any suggestions on where to find more information about the company.”

What would you do if you were given a deadline and you realized that your current approach to the project would not meet the requirements?

This question is an opportunity to show your problem-solving skills and ability to adapt. Your answer should include a specific example of how you adapted to the situation, what steps you took to complete the project on time and any additional information that may be relevant to the interviewer.

Example: “In my last role as a senior database developer, I was tasked with creating a new system for tracking customer data. The deadline was two weeks away, but after reviewing the requirements, I realized that it would take me longer than expected to create the system because of its complexity. Instead of trying to rush through the project, I spoke with my manager about my concerns and proposed alternative solutions. We decided to hire another database developer to help me meet the deadline.”

How well do you perform under pressure and what is your strategy for managing deadlines?

The company wanted to be able to store all of their customer information in one place so they didn’t have to use multiple databases for different functions. I created a system where we could store all of our customer information in one database while still being able to access it easily.”
