Understanding the SDLC is crucial for any software engineer, as it outlines the process of developing software from inception to deployment.

How to Answer

Discuss the phases of the SDLC, such as planning, design, development, testing, deployment, and maintenance. Provide examples of how you've applied these phases in your previous projects.

Example

"I have extensive experience with the SDLC, having worked on multiple projects where I was involved in all phases. For instance, in my last project, I participated in the planning phase by gathering requirements, followed by designing the architecture, coding the application, and finally testing it before deployment. This comprehensive involvement helped me understand the importance of each phase in delivering a successful product."

2. Describe your experience with mobile app development, particularly with Swift and Kotlin.

Given the focus on mobile applications, your experience with these languages will be critical.

How to Answer

Highlight specific projects where you used Swift for iOS or Kotlin for Android development. Discuss the challenges you faced and how you overcame them.
