Alex: Hey. This is Alex from Skill Society, and I'll be conducting your interview today And just to note that this conversation may be recorded for training purposes, but before we get started, could I start by grabbing your full name?

Candidate: Daniel Mosley.

Alex: Thanks for providing that, Daniel. Before we get started, I just wanted to explain a bit about what to expect. Our interview today will involve asking you some prequalifying questions covering a range of topics, To help us learn more about you and to get a better understanding of your experience, the interview should only take around 10 to 15 minutes so I won't take too much of your time today. Um, if that all makes sense, are you okay to get started?

Candidate: Yeah. Let's let's start.

Alex: Great. Can you describe the difference between block and inline block elements, in CSS? In what scenarios would you use each?

Candidate: Yeah. I would use a block element when I'm I'm trying to um, have an element. Just isolation on its own. Um, when it says when it when you use inline block elements, it's typically when I want a row of items to line up in a certain way or manipulate it in a certain way. That You know, I can program the the browser to understand that expecting know, there's gonna be a line or, you know, continuation of the same passion, not following up from that. In scenarios, I'd use for each. So, um, block element, I'd probably use a block element for a logo where it's a 1 off item that was probably in the top left. Section of a website with existing patterns and um, inline block elements, um, navigation, I are really simple ways to um, utilize this. It can either be horizontal or vertical. Um, it just depends on the app in question.

Alex: Thank you for your response, Daniel. It sounds like you have a solid understanding of when to use block and inline block elements. Now let's move on to the next question, Can you explain how event delegation works in JavaScript and provide an example of when it might be used

Candidate: don't know what that means. And, you know, I I can't provide an example. I'm sorry.

Alex: That's completely okay, Daniel. It's important to be honest about what you know and what you're still learning. Event delegation can be a bit tricky if you haven't encountered it yet. Let's move on to the next question, What are the key differences between React's class components and functional components with hooks? When would you choose 1 over the other?

Candidate: don't honestly know the answer to that. I've not really used React, um, at all.

Alex: That's perfectly fine, Daniel. It's great that you're being open about your experience. React can be quite a shift if you haven't worked with it before. Let's continue with the Question. How do you manage version control in a collaborative environment Can you explain a situation where resolving merge conflicts was challenging?

Candidate: Uh, Yeah. I manage it. So we use version control. We use GitHub. Um, and then it's around, you know, we aim to release smaller, um, elements um, that have tests in smaller components, so then we're not having branch that build up over time, and it becomes a a a pain to to merge and Uh, from different developers point of view. Um, an example where an issue was faced were we need to merge um, 2 different developers, um, merge conflicts and I think both, you know, both these developers, like, 1 was a front end, 1 was a back end. And then we also had another front end working on the same kind of products. Needed to collaborate and communicate outside of the the GitHub to make sure we're on the same page. However, you know, when it came to merging, there was a lot of the, uh, conflicts in terms of, um, things that we needed to resolve because we were working on similar parts of the product. Similar parts of the interface. And we, I accidentally manipulated in different ways and in 2 different ways. Uh, myself and the other front end developer. Um, so that's our own communication and sitting with each other and doing a bit of per programming to understand how we can fix this, um, and come to a resolution that solves for 5 problems. And adapt 1 of our approaches if if need and speak.

Alex: Thank you for sharing that experience, Daniel. It sounds like you handled the situation. Well through communication and collaboration. You're doing great so far, and we're just passed halfway through the assessment. Now let's move on to the next question, How would you handle API errors in a React application? What steps would you take to ensure the user experience is not negatively impacted?

Candidate: Uh, usually, silently. Showing these API errors. I'll make sure we have fallback um, in place when it comes to every element expect expecting, some feedback for for the users specifically, um, to make sure we don't impact the user experience too much, and then also actually building the functional capabilities for for users that also launch issues that they can observe and and over time as well. So making sure we're on top of issues that come up and, uh, customers are facing as well.

Alex: A thoughtful approach, Daniel. Ensuring a smooth user experience while handling errors is crucial. Now let's move on to the next question. What techniques do you use to optimize the performance of a web application? Can you provide an example where performance improvements had a significant impact?

Candidate: A simple example would be to use libraries and, you know, make reusable components where we'd almost have the same pattern repeating it again and again, and we can basically build on top of that. To make sure it's not too complicated, but it becomes this complex Goliath of a of an element that we need to maintain, but, um, making sure we're, you know, tactically tactically um, adapting you know, and reusing components as and when can we can you know, we can. 'll help. Improve performance because then we're not loading Additional UI elements together. It's it's, you know, there's less cost. Um, but when it comes to web application performance on the whole, I I Done. Have any concrete examples for you. I'm sorry.

Alex: Thank you for your answer. Daniel. Reusable components can indeed help streamline performance and maintainability, completely fine if you don't have a specific example at the moment. Uh, let move on to the next question. How do you ensure cross browser compatibility when developing a website or web application? Can you share an example of an issue you faced and how you resolved it?

Candidate: Yeah. I a lot of developers work in Chrome, and and I take the approach of working Safari, uh, because a lot of errors do pop up. Um, that, um, observable via Chrome as well. And uh, obviously, that's just as we're developing and we did and, yeah, we can kind of observe issues that come up as well, but we typically run all our our code through Litmus um, to make sure it's it's, you know, both functioning and visibly it's it's not breaking on various number of supported browsers. And, you know, we'd look for the last what's what's the latest versions of, uh, particular browsers, and we'd do it you know, kind of support up to a certain point. Um, if you have browsers not supported older than that, we typically redirect you to a message to upgrade your browser and add you know, to notify their customers that the browser of choice is not supported.

Alex: Thank you for sharing your approach, Daniel. It's great to see that your proactive about testing across different browsers and using tools like Litmus. Now we have just a few more questions for our records before we close off the interview. What approach do you take to ensure that a web application is fully responsive? How would you handle a situation where a Design breaks on a specific device size.

Candidate: Approach I typically work with the designers to make sure um, they've covered all the bases when it comes to responsiveness. Um, obviously, that behaves differently in, you know, in design product like Figma versus the actual end user. Um, when it comes to breaking a specific size, I'll work collaboratively with the designer at the time. The product owners, to make sure, um, we could get those issues resolved as quick as possible.

Alex: Great to hear that you prioritize collaboration with designers and product owners to address responsiveness issues. Communication is key in those situations. Now for the final question, in your opinion, how important is communication between front end and back end teams? Can you provide an example where clear communication made a difference in the project's outcome?

Candidate: Uh, yeah. No. It's it's very it's super important. Typically, sometimes the back end might do more work ahead of the front end and the front end will do more work ahead of the back end. And communication is not really Uh, the channel is often, and it's not consistent. Um, typically, 1 team ends up building something that the other team isn't really factored into the the scope of work, and and it's our own collaborating together with both both of those. Specialties to make sure um, you know, what we're building is fit as spectrum, you know, fit fit for the customer as well.

Alex: Thank you for sharing your thoughts on the importance of communication between teams. Daniel. It's clear that you understand how vital it is for successful project outcomes. Now for the last question, how do you stay current with new front end technologies and ensure that you're improving your skills?

Candidate: Hi. Follow a lot of articles on Medium and, you know, people that that typically fall for into, like, CSS and HTML and React and things like that. You know, when new technologies do emerge and I kinda do a proof of investigation to make sure um, I'm aware of them and, you know, what the foundation, I foundation ideas are behind that as well. And, you know, it just gives me a good perspective on what's out there, what's been developing, what's changing, what's adapting, new approaches, and things like that.

Alex: Thank you for your answer, Daniel. It's great to hear that you actively seek out new information and stay updated on industry trends. That's all the questions from my end today.
