2. How do you approach debugging and solving errors in your code?

• Example Answer: “I start by reproducing the error to understand its context, then analyze logs and use debugging tools specific to the programming language. If necessary, I collaborate with team members to get additional perspectives. This approach helps me systematically identify and resolve the issue.”

3. What programming languages do you know, and which do you prefer to use?

• Example Answer: “I’m proficient in Java, Python, JavaScript, and C++. For data analysis and scripting, I prefer using Python due to its versatility and vast library support. For web development, I typically choose JavaScript, specifically React, because of its flexibility and strong community backing.”

4. How do you manage your time and prioritize tasks in a complex project?

• Example Answer: “I rely on prioritization techniques like the Eisenhower Matrix to distinguish urgent tasks from important ones. I also use the Pomodoro Technique to maintain focus and avoid burnout. This approach ensures I remain productive and organized throughout a project.”

5. Do you have experience with Agile or other development methodologies?

• Example Answer: “Yes, I have experience working with the Agile methodology, particularly Scrum. I’ve participated in sprint planning, daily stand-ups, and retrospectives, which helped the team stay aligned and deliver functionality in iterative cycles.”

6. How do you stay updated on new technologies and programming trends?

• Example Answer: “I attend industry conferences, follow top tech blogs, and take online courses on platforms like Coursera and Udemy. I’m also part of several programming communities where we discuss emerging technologies and exchange ideas.”

7. Can you describe a situation where you collaborated closely with another team?

• Example Answer: “In my last project, I worked closely with the design team to develop a user-friendly mobile app. We had regular meetings to align on user experience and visual elements, which helped us deliver a cohesive and visually appealing product.”

8. What personal or open-source project have you created, and why?

• Example Answer: “I developed an open-source expense tracker using Python and Django. My goal was to learn more about web frameworks while creating a tool that could help others manage their finances. The project received positive feedback and contributions from the community, which motivated me to keep improving it.”
