Ques:- What is CORS and how does it affect API development
Right Answer:
CORS, or Cross-Origin Resource Sharing, is a security feature implemented by web browsers that allows or restricts web applications from making requests to a domain different from the one that served the web page. It affects API development by requiring developers to configure their APIs to specify which origins are allowed to access their resources, ensuring that only trusted domains can interact with the API.
Ques:- What is the difference between REST and SOAP APIs
Right Answer:
REST (Representational State Transfer) is an architectural style that uses standard HTTP methods and is typically more lightweight and easier to use, while SOAP (Simple Object Access Protocol) is a protocol that relies on XML for message format and has strict standards for security and transactions. REST is generally more flexible and faster, while SOAP is more suited for enterprise-level services requiring high security and reliability.

In such cases, I focused on facilitating open dialogue by organizing a meeting where everyone could express their concerns and ideas.

Ques:- Your client is a large electric utility company. Consolidation has been widespread in the utilities industry and your client wants to know if they should be jumping on board this trend. What advice would you give them?
Right Answer:
I would advise the client to conduct a thorough analysis of their current market position, financial health, and operational efficiencies. They should evaluate potential synergies, cost savings, and growth opportunities from consolidation. Additionally, assessing the competitive landscape and regulatory implications is crucial. If consolidation aligns with their strategic goals and offers clear benefits, it may be a good move; otherwise, they should consider organic growth or partnerships instead.

I listened actively to their concerns, apologized for the inconvenience, and assured them I would resolve the issue promptly. I contacted the logistics team to expedite the shipment and provided the customer with regular updates.

I assess my role as crucial in diffusing the situation by remaining calm, showing empathy, and taking immediate action to resolve the problem.
