Thanks for sharing the feedback and we are grateful to resolve your queries related to fresher and experienced hiring and also want to explain about the questions that we usually ask during the interview. First example for the questions you mentioned: Is ACID in transactions: It means Atomicity, Consistency, Isolation, Durability and to implement transactions if we have the basic knowledge that what are the benefits only then we can implement transactions. I agree that one who recently passed from the college can answer better for the question but only in terms of definition. If we are talking about actual use of ACID in transactions then only experienced person can explain because they used these during development. Second question is Database Engines. Hope you know what are engines and what is the importance of these. Because if you not have the basic knowledge of the engines then how one can use best engine for their project and how one can decide if we have to use the transactions in database and we select the innodb then it is not possible and this is the question we assume that only experienced person can answer because these terms and explanation only known to experienced person. So it is not possible to differentiate between the questions on the basis of experience but yes answer can differentiate if the person is experienced or not. We would like to thank you for showing interest towards our organization, every feedback helps us to improve better. Hopefully we have resolved your issue here.
