Typically in an interview, the details don't make as much difference as your willingness and ability to understand the system as a whole; _immediately_ divulging technical particulars and esoteric specificities about a given system doesn't lend much of a view on how you would approach a problem. Laying out the simple facts of the simple concepts is a great way to start and make clear your mental model, without confusing or concerning the questioner about complexities. The cloud is a complex ecosystem and details change all the time, but the core fundamentals will always help you at least narrow down your research, or even realize at a glance what the root cause is.

I've gone through several interviews throughout my career and here are a few key points I always keep in mind: 1) Some questions can deliberately be kept open-ended to specifically test your knowledge and reasoning. 2) It is important to ask as many follow-up questions required to get a thorough understanding of the original question. 3) Do not hesitate to ask for a few minutes to think or a pen and paper to visualize an architecture.

1. Ask for Clarification 🤔: If a cloud computing question seems unclear or too broad during an interview, don’t hesitate to ask for clarification. It shows you’re attentive and committed to providing a thoughtful answer. 2. Inquire about Details 🔍: For instance, if you’re asked how you would implement a particular cloud solution, inquire about the scale, the specific needs of the business, or any preferences they might have regarding cloud providers. 3. Tailor Your Response 📝: This approach will help you tailor your response more effectively and demonstrates your analytical thinking.

❓ "Don't hesitate to ask." 🧩 "A clear mind leads to clear answers." ❓ Ask Follow-Up Questions 🧩 Rephrase to Confirm Understanding 🔍 Address Ambiguities 💬 Engage in Clarifying Dialogue ❓Clarifying doubts involves seeking clarification on any part of the question that is unclear, ensuring you fully understand what is being asked before responding. 🔍 Crucial for avoiding misunderstandings and providing accurate, relevant answers. 🛠️ Focus on asking follow-up questions, rephrasing the question to confirm understanding, and addressing any ambiguities. 🌟 For example, if an interviewer asks about a specific cloud technology you're unfamiliar with, asking them to explain can give you more context to answer effectively.

If you don’t understand the question, don’t hesitate to ask for clarification. This shows that you’re thorough and want to provide the most accurate answer. For example, if asked about cloud storage, you might ask, Are you referring to object storage like S3 or block storage like EBS?

If you encounter a difficult question, take a moment to compose yourself before answering. This helps in reducing anxiety and organizing your thoughts. If the question is unclear, don’t hesitate to ask the interviewer to clarify or elaborate. This shows that you’re thoughtful and thorough. If you don’t know the answer, it’s okay to admit it. Don't say "I don't know it" instead you can say something like, “I’m not sure about that, but here’s how I would approach finding a solution…” This shows your problem-solving mindset and willingness to learn.

Example matters when you want to explain technical terminology with easy way... So consider i want to explain hub and spoke model...to theoretically its vast..but if i given example so all public facing cloud resource like fire wall in hub network and private resources like database will be in spoke network

Let me share a real-world example to illustrate this. At my previous company, we implemented a disaster recovery plan for our e-commerce platform hosted on AWS. Here’s how we did it: We used AWS S3 for daily backups of our databases. S3’s versioning feature allowed us to keep multiple versions of our data, ensuring that we could restore from any point in time. We set up AWS RDS with Multi-AZ (Availability Zone) deployments. This automatically replicated our database to a standby instance in a different AZ, ensuring that if the primary instance failed, the standby would take over seamlessly. We utilized AWS CloudWatch for monitoring and AWS Lambda to automate recovery processes.

Illustrate your points with examples from your experience. For instance, if asked about scalability, you could say, In my last project, we used AWS Auto Scaling to automatically adjust the number of EC2 instances based on traffic load, ensuring high availability and cost efficiency.

When faced with challenging cloud computing question, whenever possible, use examples from your own experience to illustrate your points. This adds credibility to your answers and shows practical knowledge. If you don’t have personal experience, refer to well-known case studies or industry best practices.

Demonstrate your ability to learn and adapt to new technologies. You might say, While I have extensive experience with AWS, I recently started exploring Google Cloud’s offerings and have successfully migrated a small application to test its services.
