How to Find a Balance Between Work and Life: 4 Interview Questions and Sample Answers
Here are some answers to questions that you can use as models for your own:
1. What are some good things about round-robin load balancing, and what are some bad things?
You can show how well you understand technology and how well you can solve problems by answering this question. When answering this kind of question, it’s important to show that you know exactly what the interviewer is asking and give a full answer.
Example: “Round-robin load balancing can be a good solution because it is easy to set up. The round-robin system lets servers take traffic in a set order and switch between them so that no one system gets too much traffic. This system can be simple to use, but it also has some problems. Since the round-robin system can’t tell the difference between different kinds of servers, it’s hard to make it work better. Some servers can’t handle certain types of traffic, but a round-robin system sends traffic to servers without taking their types into account.”
2. What does “fail over” mean in the context of a load-balancing system?
If an interviewer asks you to explain a technical term like “failover,” you might want to show that you know how the industry talks. It’s important to give a detailed answer to this kind of question that shows you know a lot about the topic.
Example: “The thing that a load-balancing system does when one of its servers dies or stops working is called “failover.” If you don’t want to lose traffic or have problems when hardware fails, you need a system that can handle a failover. Most failover systems are set up to simply send traffic from a server that isn’t working to a server that is. Every machine in the system needs to have its heartbeat checked often, so that if something goes wrong, failover protocols can take over.”
Talk about what a reverse proxy server is.
When you interview for a job as a load balancer, the interviewer may ask you about the different kinds of servers. Understanding how different types of servers work together to handle a site’s traffic can be an important part of this job, so employers may want to make sure they hire people with the right technical skills.
Example: “A reverse proxy server is a system that works between the site user and the live server of the site. Before it gets to the site’s host, a reverse proxy server stops traffic. This lets the person in charge of load balancing sort the different types of traffic. This kind of server can help protect the host site from DDoS attacks and make sure that the traffic processing load is spread out in the right way.”
4. How can the round-robin algorithm for balancing loads be changed in different ways?
Some of the questions an interviewer asks go into great detail about a certain part of the job. Even though it’s important to show that you know what you’re doing, it might also be important to show that you keep getting better and are always willing to learn more about your field.
Example: “I know that there are different kinds of round-robin, like weighted round-robin and dynamic round-robin. Weighted round-robin is a system in which each server is given a grade or weight so that traffic goes to the server that can handle it best. In the weighted system, these grades don’t change in real time, but in the dynamic system, they change all the time to reflect how many people visit the site. I only know about these differences, but if there are any others I should know to do my job better, I’d be happy to learn more.”
