What is your expectation from company?
Have you ever deployed containerized application into AWS infrastructure
Recruiter scheduled a call where she briefed about what I can expect in the first round. As she mentioned my first 1:1 was 80% technical and about 20% behavioural questions. First round: Most of these questions are repeated in most of the Amazon interviews. Please go through at least 20 interview experiences posted in Glassdoor. Glassdoor is a Saviour for everyone here. Tell me about yourself? Why/what did you find interesting in the role you have applied for? - These questions are taken very seriously in Amazon. Please prepare very well. Watch Dan Croitor's tips on how to answer these questions on Youtube. Spend at least a day coming up with an effective answer to these questions. Don't give hypothetical answers. These answers should be personal to your profile. Pick keywords from your JD and use them when you answer these questions. Adapt the answer to fit to Amazon's Leadership principles. Technical questions: What are micro services? What are the advantages/disadvantages of using them? What is content delivery network? How is it beneficial? Differences between Authentication & Authorisation? RTO & RPO? When do you use VMs vs Dockers? Real time examples? Differences between SQL & NoSQL and when to pick one over the other? Differences between compiled languages and interpreted languages? Examples for these What is Envelope encryption? Learn symmetric & Asymmetric encryption mechanisms What is your most favourite AWS product? why? Be ready to give every possible answer to this question, they will dig deep. Sample CI system example (From Code commit to Deployment) What will you do if you get to know that you will receive 100 times more transaction for your DB in next 10 days? How will you solve without using any server-less product? What are the main factors to keep in mind when you are architecting a new product? (Answer can be Multi-tier, event-driven, Micro-services architecture)? If your application performance is bad, what will you do? How will you debug? How will you monitor your Network traffic performance? (May be VPC flow logs, transit gateway nw manager, Cloud watch logs..) What are stateful and stateless applications? Can you create a container as a stateful resource? What are the different types of scaling? Can you scale a SQL DB horizontally? Behavioural questions in First round: These should be answered in STAR method. Watch Dan Croitor's tips for AWS interviews on Youtube, There are extremely helpful. What did you learn outside your work, which you used to improve your work life? What was the situation when you took a task outside the scope of your work and delivered results? Loop interview of 5 rounds was scheduled in 2 weeks after my result of first interview. I had 3 rounds on one day & 2 rounds on the next day. Most likely, it will be all on the same day, if your/interviewers' schedule work. My recruiter spoke to me several days before my Loop interview, and briefed about how these interviews happen and how you will be rated, this information was helpful. If you are being hired for technical role, then you can skip few Leadership principles which will not be asked about in your Loop interviews. For instance, Hire & develop the best or Frugality, these are tested only if you are being hired for managerial positions. So, be thoughtful of what Leadership principles are needed for your profile and prepare for them. I prepared at least 30 different situations which was mapped into one or more Leadership principles. Watch Dan's most asked 35 questions in Amazon interview in his Youtube channel and the entire 150 questions set. It will help you prepare for all kinds of questions possible. Find others who are giving Loop interviews and do at least 3-4 role plays with them. If not, practise answering these leadership questions out LOUD in front of a mirror. We underestimate this factor. Only when you speak the answers out loud, you will find your faults. Do not repeat your stories with different interviewers, since they compare their notes after your interview, before making their decision, which was also mentioned by my recruiter.

Case Study: There are multiple platforms operating across AWS, Azure, and a legacy hosted datacenter. The organization is under pressure from the board and investors to improve operating leverage by reducing infrastructure costs by at least 20% without sacrificing reliability, security, or customer experience. The AWS and Azure environment includes a large footprint of instances and under-optimized storage. Meanwhile, a hosted datacenter continues to house legacy workloads, with a colocation contract extending another 18 months and aging hardware nearing replacement. This hybrid reality creates complexity, inefficiency, and risk. You’ll have one week to prepare, and the final session will be a 60-minute interactive presentation where you’ll share your insights and plan. This exercise is intended to remain high level—it is not about detailed implementation specifics but rather about how you think through challenges, set priorities, and drive transformation. The goal is to facilitate discussion, surface your ideas, and understand how you approach cost management, trade-offs, and executive communication."
