If We Ask You To Design A Garbage Collection For Our Clients How Will You Do It
Garbage collection guarantees that a Java system runs properly and saves the programmer from having to perform it manually. A GC improves memory efficiency in systems. The purpose of garbage collection is to make a system appear to have an infinite quantity of memory. When a system becomes sluggish, a garbage collector enters and gathers what is no longer in use.
As a hiring manager, you need to pay attention to this answer, as through this, you will figure out whether the candidate is able to design the ins and outs of the system and have an efficiency moderation check in place, which was the deliverable that the client required.

Software Engineering Interview Questions With Answers
What should you expect in your first software engineering interview? That depends on the role youve applied for! Software engineering jobs tend to fall under two categories: domain-specific or general programming.
If youre interviewing for a domain-specific role, expect the questions to center around the specific technology you specialize in, such as AWS or cloud infrastructure, or IoT. These highly-technical interviews will be very focused on the technology in question.
For a general programming or web development role, the process is fundamentally different. These interviews evaluate your problem-solving ability as well as your coding proficiency, so recruiters are likely to ask questions ranging from the technical to the behavioral. Its this general sort of role that were focusing on for this article.
In this blog post, weve compiled a list of 31 most common software engineering interview questions asked in a software engineering interview along with the best ways to answer them.

Question 30: What is a Delegate? Explain.
Answer: A Delegate is a variable that holds the reference to a method. Hence it is a function pointer of reference type. All Delegates are derived from System.Delegate namespace. Both Delegate and the method that it refers to can have the same signature.
public delegate voidAddNumbers
After the declaration of a delegate, the object must be created of the delegate using the new keyword.
AddNumbersan1 = newAddNumbers
The delegate provides a kind of encapsulation to the reference method, which will internally get called when a delegate is called.
public delegate intmyDel public classProgrampublic voidStart }
In the above example, we have a delegate myDel which takes an integer value as a parameter. Class Program has a method of the same signature as the delegate, called AddNumbers.
If there is another method called Start which creates an object of the delegate, then the object can be assigned to AddNumbers as it has the same signature as that of the delegate.
Question 31: What are Events?
Answer:Events are user actions that generate notifications to the application to which it must respond. The user actions can be mouse movements, keypress and so on.
Programmatically, a class that raises an event is called a publisher and a class which responds/receives the event is called a subscriber. An Event should have at least one subscriber else that event is never raised.
Delegates are used to declare Events.
Let us see an Example:
Use Natural Skill Tests When Interviewing Senior Engineers
- Do not ask senior developers to complete a test to explain a simple algorithm or data structure- most candidates for senior posts havent dealt with such matters in years.
- Stay away from whiteboard-testing.
- Ask candidates to share a few work samples
- Ask the candidate to build on existing code
Likewise, instead of asking candidates to take a coding test like in a coding interview, it would be better to ask a potential senior developer how they would improve upon existing code.
This can be achieved with a DevSkiller paired programming test . See how your candidate approaches and solves problems, including how they prioritize which problems to solve. Additionally, see how your candidate uses in stack resources like frameworks and libraries and observe when they choose to write their own code

What Do You Think Are The Most Important Aspects To Pay Attention To When Reviewing Another Team Members Code
Code reviews are fundamental to the software development process, even when theres only one engineer. By posing this question youll get an idea of the candidates knowledge and problem-solving skills, their attention to detail, and whether they can keep an overview of the project.
Here is a sample answer:
I first look for security, functionality, and readability. Is the code simple, or cluttered, bloated, and inefficient? How many lines of unnecessary code will I need to re-write or remove? I check for any weaknesses that could cause vulnerabilities and confirm that regulatory requirements have been met.
Everyone has their own coding style and every developer or team will have requirements that are specific to their codebase. Effective code reviews often have checklists. Below is a limited list of general suggestions you could consider including:
- The software passes automated and manual testing
- Code follows applicable conventions and is easy to understand
- Code is not duplicated
- Blocks of code inside loops are as small as possible
- No memory leaks
But more important than which exact points a candidate brings up is their reasoning for doing so. Be wary of candidates who get stuck on tabs-versus-spaces bikeshedding at the expense of more crucial engineering elements: The above items shouldnt all carry the same weight.
Here are ten examples of terms they should be able to define:

How Do You Refactor Classes For Parallel And Concurrent Processes
Similar to refactoring classes for easier unit testing, your ability to refactor classes for parallel and concurrent processing shows the interviewer your understanding of working with non-deterministic programming. In your answer, give examples of how you used threads, background jobs and sub-processes when implementing solutions to support improvements in software designs.
Example:”When refactoring classes on a recent build, I applied asynchronous processing to manage my organization’s financial databases. By designing parallel and concurrent processing features, I was able to improve the functionality and speed of data retrieval of various user applications. Since the size of the data structure was so large, multiple background processes previously hindered the system’s processing speeds. With concurrent processing, however, my team was able to apply solutions more effectively when updating system data each accounting period.”
