  1. Can you describe a time when you faced a difficult programming problem, and how did you solve it?

Answer: In my previous job, I was working on a project that involved integrating multiple systems using RESTful APIs. I faced a challenge where the system was not returning the expected data, and I spent several hours debugging the code to identify the issue. Eventually, I found out that the API was returning a different data format than what we had anticipated, and I had to make changes to the code to accommodate the new format.

2. How do you stay up to date with the latest technologies and advancements in the Java ecosystem?

Answer: I stay up to date with the latest technologies and advancements in the Java ecosystem by attending conferences, reading industry blogs and articles, and participating in online forums and communities. I also dedicate time each week to learning new technologies and experimenting with new tools and frameworks.

3. Can you tell me about a project where you had to collaborate with a team, and how did you handle conflicts or disagreements?

Answer: In one of my previous projects, we had a disagreement over the choice of technology for a specific module. We had to weigh the pros and cons of each option and come to a consensus. To resolve the conflict, we held a meeting and discussed the different options, and we ultimately decided on the technology that best suited our project’s needs.

4. Can you describe your approach to debugging a complex issue in your code?

Answer: My approach to debugging a complex issue in my code is to start by analyzing the logs and error messages to identify the root cause of the problem. I also use debugging tools like breakpoints and step-throughs to isolate the issue and narrow down the scope of the problem. I also reach out to my colleagues for their input and guidance in resolving the issue.

5. Can you tell me about a time when you had to learn a new technology or programming language, and how did you go about it?
