I applied online. The process took 7 weeks.

The process took around over two months.

First I had an HR email round, yes an email round, the HR at Amazon are the worst I have ever seen in my life. Then there was a technical screen call, a video call on their Amazon Chime software that crashes every few seconds. lolx.

Then there was this SUPER day (They still believe in Ancient ways) 5 interviews all in one day, but I requested to split in two different days. As I have a life too BRO.

After that an HR call to inform the final verdict, they insisted on having a call rather than sharing the outcomes in an email. They requested to arrange a call for an update on my application on FRIDAY evening, and then had a 2 minutes call and kept me in worst situation you could ever be on Friday night. I have overall the WORST experience with AWS/Amazon.

A bad interviewer can RUIN your potential career at a tech Giant.

• First Assessment for System Design recommendations evaluations
• Then a second interview (tech screening interview) started with Role overview. My background. Coding test (find out the second smallest and second largest number in the given very large array). Discussion around the Software design approach where a transaction processing system is being built. How would you handle the load during events like christmas. What is event-driven-architecture? How it could help in the scenario with the online shop software? How would you make sure that the catalog having only one item left to be ordered is ordered by one person, and at the same time not accept the same item's order from a different person (or same person again). Basically updating and managing the state of the items in an ecommerce website. How would you avoid having a single point of failure? Then, discussion went into the adding Queuing capability into one of the services. What is high cohesion? Why is low coupling helpful and how is that achieved? We further discussed the Microservices and containerised approach for architectural discussions. How the low cohesion helps in the microservices architecture? What are the pros and cons of using Microservices architecture? How many ways the microservices may communicate with each other? Why would you choose a Microservices, vs VM deployment, vs the serverless? Why and when would you use the lambda functions? Authentication vs Authorisation? How can you make sure the least privilege principle? What is RBAC? How it could be implemented? Have you heard of the SOLID principles? What dependency inversion is? What is inversion of control? Should a class have only one responsibility as per SOLID principles, so what about the functions in a class? What is TDD? What SOLID principle adheres to unit testing? What is mocking? What SOLID principle are advocating for mocking during unit testing? Then interviewer asked me about the Databases that I worked, then he went onto asking question about documents based database, how the retrieval happens. then what if the hashing mechanism have duplicates (keys)? Interviewed changed the gears and then moved on to the scenario based questions where they expect you to answer a STAR based answers. Tell me a difficult situation during a project work? Tell me a situation where you were unable to deliver? Then interviewer gave me a chance to ask any question. I asked how does the team works and responsibilities of individual team members. Moreover, whats the next process? Any more technical rounds?

Super day interviews:

• System Design: Went through my resume, asked a couple of queries there, talked about RAG, what AI you worked on? how did you use AI to carry out a project in your resume? Why did you not used AI if you didn't? API management, what Clouds you worked on? chance to ask. REST API vs GraphQL? API version management? What are CDNs and how many do you know? Followed by some leadership principles, and chance to ask.
• Hiring Manager Interview: Best three leadership principles, worst leadership principle in your opinion. Why AWS? What is your high and low moments of your carrier? Leadership principles: Speed vs Quality? chance to ask.
• Tech Fit Interview: held with Tamara+Sara: tamara kept herself behind curtain all the times and appeared in the last two minutes on the CHIME software. While Tamara was senior she let a Junior take the interview. The Interviewer Ms. Sara was Not the best communicator. The network lag was there in Amazon CHIME, the audio was distorted, I tried to connect using dial in via phone, over there the audio was even worse. Had to skip a couple of questions due to the audio issues with Amazon chime software. This could have been improved over the years. Technical start, Cloud architecture, asked for examples on cloud native apps, give examples for microservices you worked with. What tech stack you choose, and why? what visualisation did you choose, how did you decide among many options for the visualisation. Give a project example which is not Data pipeline specific, no ETL etc? Interviewer asked some other vague questions that needed to clarified, do clarify the context of the question. Followed by a coding test. again same second smallest and second largest number coding exercise. Last question whether I have worked on modernisation? Give an example of system you built/designed without data pipelines?
• Fourth Interview with Chiragh: Adoption to a current software you are working on, onboarding, Anything you did exceptional (going out of the way) that helped a client and your own employer? Example of a problem you faced and you step up to resolve it without being asked by management? tell me a time when you worked to resolve an issue?
• Fifth interview with Mr. Olu: (he was the only coolest interviewer at Amazon TBH) Behavioural questions with minor level details. Focused on leadership principles including Bias for Action. Tell me about a time you had to dive deep into data to solve a problem. Give me an example where you have to take a risky action without consulting others? Give me an example of time when you went out of the way and did something that helped your team? Example where you went above and beyond for customer?
