• 5. How do you approach problem-solving in your work?
  Answer: I follow a systematic approach to problem-solving. First, I gather all relevant information and analyze the issue from different angles. Then, I brainstorm and evaluate potential solutions, considering the pros and cons. Finally, I implement the most feasible solution and test it thoroughly before making any changes.

Situational Questions

• 6. You encounter a bug in the system in the middle of a deadline. How do you handle the situation?
  Answer: In such a situation, I prioritize the critical tasks and work on fixing the bug with the highest impact on the system. I also communicate the issue to my team and together we work on finding a solution. If needed, I re-prioritize tasks and allocate extra resources to ensure the project is completed on time.
• 7. Give an example of a difficult decision you had to make on a project. How did you handle it?
  Answer: In a previous project, the client requested a feature that was beyond the scope of the initial agreement. I had to decide whether to incorporate the new feature and risk missing the deadline or stick to the original plan. After assessing the risks and impact, I decided to communicate the situation to the client and the team and came up with a feasible solution that satisfied both parties.
• 8. How do you handle conflicts with team members on a project?
  Answer: I try to listen and understand the perspective of my team members and encourage open communication. If a conflict arises, I address it calmly and objectively, focusing on finding a solution rather than pointing fingers. I believe teamwork and collaboration are key to successful project outcomes.
• 9. You are tasked with developing a new embedded system. How do you ensure it meets the required specifications and quality standards?
  Answer: To ensure the system meets the specifications and quality standards, I follow a strict testing process that includes both unit testing and system-level testing. I also regularly communicate with the stakeholders and seek feedback at different stages of development to ensure their requirements are met.
• 10. How do you handle unexpected changes in a project plan?
  Answer: When faced with unexpected changes, I assess the impacts and communicate them to the team and stakeholders. We then work together to come up with a new plan that takes into account the changes and minimizes any disruptions to the project timeline.

Technical Skills & Experience
