ChatGPT - Linux interview questions and answers for 1 year experience

[kittydesade]

I'm very sorry. Six months ago you commented on a Gordon Ramsey accessibility post that your job to help make websites accessible. How do I get that job? I would love that so much. I'm sure you've answered this before but I can't find it.

I, too, am sure I've answered this before, but I can't remember where and I'm not about to brave the Tumblr search feature to go looking, so you and @the0dd0ne get a twofer.

Hi, I'm not a bot, and I was wondering if I could ask you a weird career question? I saw your addition on that "Accessibility Nightmares" post where you mentioned it's your actual job to email websites about their lack of accessibility and what they need to do to make it accessible, and can I ask how you got into that? I got injured on the job and need to make a huge career change, and that type of work has always been really interesting to me, but I don't even know where to start to get into it! Also feel free to ignore this lol I know it's out of left field.

(This is actually the third question I've got on this, so no, not that out of left field.)

So the first thing to understand is that it's actually pretty hard to get into digital accessibility because there just aren't that many companies doing it. As far as I know from company meetings there aren't that many schools teaching it as a part of their core web development curriculum. It's just not that common to think about it as part of web development. Which is vastly irritating.

I started mucking around with the web when there was first a web to muck around on, but when the pandemic hit and my Mom suggested (in a hilarious twist of circumstances) that I go to one of those Learn to Code boot camps to get a certificate that said I actually knew my shit so I could get a job in web development. A number of these boot camps also have job placement programs and pipeline agreements with certain companies. and in a nutshell that's how I got into it. The company sent my boot camp a letter saying "we need N warm bodies" and they sent the company a list of names, I got interviewed, I got hired as a contractor, and after a couple years of good work for them I got invited to interview for a permanent position, which I got.

These days due to the state of the everything, there are probably 10-50 programmers for every open development position, depending on language and job type and company. It's a rough field out there and I got very, very lucky in my timing. But if you want to try it, the boot camp to job pipeline is probably your best bet. Ask the boot camp recruiters if they have connections to accessibility firms. If they don't, you can always try asking if they have connections to web development/site packaging firms and then check if the firms have an accessibility department. Tell the recruiter up front what you're looking to work in, and keep in mind that the recruiter's job is to convince you to give the boot camp your money. (Mine was $12k USD.)

For resources to study in the meantime, there's the A11y Project which has discussions, videos, articles, posts, etc about digital accessibility, a lot of good information. You can also look at the resources for the CPACC exam, I don't recommend taking it unless you have a few hundred USD to burn but you can definitely study up on the Body of Knowledge, which is a free PDF to download. And there is, in fact, an accessibility job board, although I don't have any experience with applying for any of these jobs cold.

The languages I use most in my job are HTML and jQuery, and I passively use (meaning I read and interpret but don't actually program in) JavaScript and CSS. This is mainly because we work with client sites and there's only so much of the client code we can touch; if there's a problem in the client code we can't touch we have to write it up and tell them to fix it. If you end up in house for some large brand you may end up working in more web development languages, but a lot of accessibility can be handled by basic HTML attributes called ARIA attributes (and roles) and there's the documentation on that. Another tool to have is your soft skills: communication, specificity of language, writing up good descriptions of what code does what so you can explain exactly what needs to be fixed where and why. You might also want to look at documentation on what makes good alt text, where it's needed, what kind of labels are standard, etc. I think you can find that in the A11y Project pages, but honestly I just learned it on the job working with senior developers.

It's a hard time to get into software development at all, let alone a niche field like web accessibility. But Europe is about to have a digital accessibility law come into effect in July of next year (that encompasses more than just the web, that's just my area of expertise) and the US is making slow but steady strides in requiring digital accessibility as well, so there are jobs out there and there might be companies hiring to capitalize on the need. There will definitely always be companies putting off conforming to regulations until the last possible minute, and then needing services and specialists. So study up, practice, and good luck!

SQL databases (like MySQL, PostgreSQL) are best for structured data, while NoSQL (like MongoDB) excels with unstructured data and scalability is a full stack developer course in pune.

3. What are RESTful APIs and how do they work?

Answer: RESTful APIs are web services that adhere to REST architecture principles, allowing for communication between the client and server. They use HTTP methods like GET, POST, PUT, and DELETE to perform CRUD (Create, Read, Update, Delete) operations on resources, usually represented as JSON data.

4. How do you ensure the security of a web application?

Answer: I ensure security by implementing measures such as HTTPS, data encryption, user authentication via OAuth or JWT, and protection against vulnerabilities like SQL injection and cross-site scripting (XSS). Additionally, I follow secure coding practices and regularly audit the code for any security gaps.

5. Explain MVC architecture in full stack development.

Answer: MVC stands for Model-View-Controller. The Model represents the data and business logic, the View is the user interface, and the Controller handles input from the user and updates both the Model and the View. This pattern ensures a clean separation of concerns, making code more modular and easier to maintain.

6. What are the differences between front-end and back-end development?

Answer: Front-end development focuses on the user interface and experience, using HTML, CSS, and JavaScript to create the visual part of a web application. Back-end development deals with server-side logic, databases, and APIs, using languages like Python, Node.js, or Java, handling data storage, and ensuring smooth communication between the client and server.

7. What is asynchronous programming and how is it implemented in JavaScript?

Answer: Asynchronous programming allows multiple tasks to run independently, without blocking the main execution thread. In JavaScript, this is implemented using callbacks, promises, and async/await. This ensures that long-running operations (like network requests) don't block the rest of the code from executing.

8. How do you manage version control in full stack projects?

Answer: I use Git for version control, employing a branching strategy (like GitFlow) to organize development. I commit frequently with clear messages and use pull requests for code reviews, ensuring collaboration and maintaining code quality. Tools like GitHub and GitLab help manage repositories and automate workflows.

9. How do you optimize a web application's performance?

Answer: I optimize performance by minimizing HTTP requests, using code splitting, lazy loading, and compressing assets like images and CSS/JavaScript files. On the back-end, I ensure optimized database queries, caching, and use load balancers to handle traffic efficiently.

10. Describe your experience working in Agile development.

Answer: In Agile environments, I collaborate with cross-functional teams, participating in daily stand-ups, sprint planning, and retrospectives. I use tools like JIRA or Trello to manage tasks and ensure continuous feedback and delivery. Agile allows for flexibility in development, with iterative progress and regular client feedback.

If you are a business looking for expert contract-based AngularJS developers in Ahmedabad, you need a strategic approach to make sure you hire the best. This guide will cover all the essential aspects of hiring AngularJS developers on a contract basis, ensuring your projects are executed smoothly and efficiently.

Why Hire Contract-Based AngularJS Developers in Ahmedabad?

Ahmedabad, one of India’s growing tech hubs, is home to many talented developers specializing in cutting-edge technologies like AngularJS. AngularJS, developed by Google, is a widely-used framework that allows for creating dynamic and robust web applications. When you hire contract-based developers, you gain flexibility and access to talent without committing to long-term contracts. Let’s explore why this model works.

Key Benefits of Contract-Based Hiring:

Flexibility: You can scale your team according to project needs without being locked into a long-term contract.

Cost-Effective: Pay for what you need when you need it, reducing overhead costs.

Access to Expertise: Contract developers, particularly in Ahmedabad, bring specialized skills that are perfect for complex projects.

Project-Specific Focus: Contract-based developers dedicate their time to completing your project within deadlines, offering efficient turnaround.

Understanding the Process of Hiring AngularJS Developers

When hiring contract-based AngularJS developers in Ahmedabad, there are several factors to consider. The demand for skilled AngularJS developers has risen significantly due to its effectiveness in creating high-performance web applications. Here's a step-by-step guide to help you navigate this process:

Step 1: Define Your Project Requirements

Before you begin the hiring process, it’s essential to have a clear understanding of your project’s scope. Ask yourself:

What is the complexity of the web application?

What features will be built using AngularJS?

How long is the project duration?

Will you need ongoing support after development?

Answering these questions will give you a clearer picture of the kind of AngularJS developer you need.

Step 2: Choose Between Freelancers and Development Agencies

When hiring contract-based developers, you can either opt for freelancers or professional development agencies. Freelancers offer a flexible, budget-friendly option, whereas agencies, such as i-Quall, based in Ahmedabad, offer a more structured and scalable solution. Agencies often provide additional benefits like project management, QA testing, and team collaboration.

Step 3: Create a Clear Job Description

Your job posting should highlight the specific skills you need in an AngularJS developer. Key technical skills include:

Expertise in AngularJS, HTML, CSS, and JavaScript.

Familiarity with RESTful APIs and AJAX.

Experience with MVC architecture and single-page applications (SPA).

Understanding of front-end build tools like Gulp, Grunt, or Webpack.

Tip: Prepare to discuss popular front-end technologies (like HTML, CSS, JavaScript, React, or Angular) and back-end technologies (such as Node.js, Python, Java, and databases like MySQL, MongoDB).

3. What is the MVC Architecture? How Does It Work?

The Model-View-Controller (MVC) architecture is a software design pattern commonly used in full-stack development to separate concerns. Understanding MVC is essential for structuring web applications effectively.

Tip: Be ready to explain how the model (data), view (UI), and controller (business logic) components interact in an MVC framework. Provide examples from your experience with frameworks like Django, Express.js, or Ruby on Rails.

4. How Do You Manage State in a Web Application?

State management is key to ensuring that data flows correctly within a web application. Interviewers will want to know how you handle state, especially in modern single-page applications (SPAs).

Tip: Prepare to discuss tools and libraries like Redux, Context API (React), or Vuex (Vue.js), and demonstrate how they help manage state across various components.

5. Explain the RESTful API Principles

Full-stack developers need to communicate between the client and server via APIs. RESTful APIs are widely used to create robust and scalable systems. Be ready to explain what REST (Representational State Transfer) is and how it works.

Tip: Understand the key concepts behind RESTful APIs, such as HTTP methods (GET, POST, PUT, DELETE), status codes, and how to design them for efficient data exchange.

6. What is CORS and How Do You Handle It?

Cross-Origin Resource Sharing (CORS) is a security feature implemented by web browsers to prevent unauthorized access to resources on different domains. It's important to understand how to configure CORS for smooth communication between client-side and server-side applications.

Tip: Be ready to explain CORS and how to resolve common issues by configuring the server to allow cross-origin requests.
