A Java Developer was asked 1w ago
Q. Describe the microservice architecture.
Ans. 

Microservice architecture is a design approach where applications are built as a collection of loosely coupled services.

  • Each microservice is responsible for a specific business capability, e.g., user authentication service.

A Java Developer was asked 1w ago
Q. Can we explicitly create a string in the string pool?
Ans. 

Yes, we can explicitly create a string in the string pool using string literals.

  • String literals are stored in the string pool by default. Example: String str = "Hello";

  • Using the 'new' keyword creates a string object in the heap, not in the pool. Example: String str2 = new String("Hello");

  • To explicitly add a string to the pool, use the intern() method. Example: String str3 = str2.intern();

A Senior Processing Executive was asked 1mo ago
Q. How would you assess the validity of the claim?
Ans. 

Assessing the validity of a claim involves critical evaluation of evidence, sources, and context.

Interview Preparation Tips

Interview preparation tips for other job seekers - Do Not join a company that doesn't respect your loyalty and at the same time is miserly when it comes to pay. They are the ultimate leaders in cost cutting and silent layoffs. They give such poor hikes that there is really really no scope for growth. I have seen people leaving the organisation because of the poor quality of projects they were offered. They are just cheap solution providers

Interview Preparation Tips

Interview preparation tips for other job seekers - The interviewer and HR exhibited a laid-back demeanour. I question the credibility of the interviewer, as he appeared to lack knowledge. The questions posed were quite basic for the job role, indicating the interviewer's unpreparedness. Communication difficulties on the interviewer's part disrupted the flow of the interview. He did not share feedback for two whole days, only providing an update after I proactively inquired with HR.
