Q3 What Is Acid Property In A Database
ACID is an acronym for Atomicity, Consistency, Isolation, and Durability. This property is used in the databases to ensure whether the data transactions are processed reliably in the system or not. If you have to define each of these terms, then you can refer below.
- Atomicity: Refers to the transactions which are either completely successful or failed. Here a transaction refers to a single operation. So, even if a single transaction fails, then the entire transaction fails and the database state is left unchanged.
- Consistency: This feature makes sure that the data must meet all the validation rules. So, this basically makes sure that the transaction never leaves the database without completing its state.
- Isolation: Isolation keeps transactions separated from each other until theyre finished. So basically each and every transaction is independent.
- Durability: Durability makes sure that your committed transaction is never lost. So, this guarantees that the database will keep track of pending changes in such a way that even if there is a power loss, crash or any sort of error the server can recover from an abnormal termination.

The most important skill that you need to possess is the approach to the problem. Oh yes, your approach should also be in such a way that you should be able to explain to the interviewer.
So lets get started!
Interview With Hiring Manager
This portion is either in person or via a phone call with the hiring manager, who would be your direct manager. The hiring manager is on your side. They have the biggest pain point, meaning that they really need to hire someone. Itâs in their best interest to be nice to you, and they usually are. That doesnât mean you wonât get tough questions. However, I ï¬nd that this ï¬rst meeting with the hiring manager is going to be one of the main chances where you get to ask speciï¬c questions about the role. For this interview, you should be ready to sell yourself. Prepare fewer questions about the company culture, and more questions about what kind of goals the manager has, what projects you would work on immediately, and their expectations for the role. The hiring manager will usually be the âeasiestâ interviewer you come in contact with. Your conversation will likely be about the role itself and your career goals, along with what relevant experience you have for the job. You should use this meeting as a chance to learn as much as possible about the job. You want to ï¬gure out: What would I be doing on a daily basis and what will it be like working with this manager? Here are some good questions to ask them in the first meeting:

How I Cleared The Amazon Sde 2 Interview
A recruiter found my profile on linkedin and informed me about an opening in Amazon for SDE 2 position. Just to provide a brief background on my profile, I am a graduate in computer science from IIT Bombay and I had 4 years of experience in software development when I was given this opportunity.
Over the course of next 2 months I went through a telephonic screening round on programming, 3 on-site interviews with emphasis on design, one bar raiser round on people skills and software design followed by another round of programming interview. It was an exhaustive process to test me on all my skills and fortunately I was able to clear it.
As I went through the rounds it was apparent that work experience was not important. The stress was on the approach to solve questions and eventually come up with a working solution. There were several instances where only the approach was required and several others where implementation was required too. I had prepared for the same and would like to share the methods of preparation.
Before getting into the actual methods I would like to set the context with an analogy to fitness.
