Top Interview Questions/Answers When Hiring Full Stack Developers?
What are the key differences between CSS Grid and Flexbox and when is it best suited to be used over another?
CSS Grid and Flexbox are two immersive layout systems however are used for distinctive cases. CSS Grid are 2D layouts which are ideal for complex layouts inclusive of multiple rows and columns extensively supporting responsiveness with features like grid template areas and media queries. Flexbox on the other hand is a 1D layout system operating in a single direction and offers responsive layout with features such as wrap and flex-direction. Overall CSS Grid is best suited for creating complex 2D layouts while Flexbox serves ideal for simpler 1D layouts.
Describe methods to safeguard a publicly accessible API from being scraped by bots.
In order to prevent bots from scraping a publicly accessible API several measures are integrated including the ones below.
Rate limiting: This mechanism restricts the number of requests made within a specific time frame preventing the frequency of the requests made.
User Authentication: User authentication mechanism such as requiring API Keys/tokens for allowing restricted user access with an additional layer of security.
CAPTCHA: CAPTCHA allows users to verify whether the user is a real human or a robot while efficiently eliminating automated scraping attempts.
What exactly is a 3-tier/3 model?
Three tier architecture is a software design pattern separating applications into three distinctive layers consisting of a presentation layer, application logic layer and the data storage layer. Each layer handles its responsibilities including presentation layer dealing with user interface, application logic for app workflows and data storage layer for managing data retrieval.
What Are Significant Technical Skills Needed When You Hire Full Stack Developers?
Proficiency With Front End Technologies
Backend Technologies Familiarity
Version control Integration
Full stack developers must work well with version control integration such as Git and its further branching strategies. This is highly required for optimizing code quality by managing code repositories while collaborating well with other developers
Deployment And Infrastructure
Hiring full stack developers include deep comprehension on working with server environments and hosting platforms along with an enhanced experience on cloud services such as AWS, Azure, or Google Cloud.
What Is The Role Of API Development And Integrations In Full Stack Development?
API development and integration in full stack development plays a crucial role of bridging the gap between the front end(client-side) and back end(server-side) components of an application. Here are some of the key roles of API in full stack development.
API provides a communication channel between the front end(client-side) and back end(server-side) serving as a standard for requesting and retrieving data. It facilitates well-structured responses allowing frontend to make API specific HTTP(s) requests ensuring consistency in data format.
Flexibility And Scalability
API’s allow decoupling of the front end and the back-end development with easy changes without affecting other components. This enhanced flexibility leverages efficient development promoting scalable architecture of the application.
Separation Of Concerns
API’s provide a distinctive division of responsibilities of front end and back end development. They serve as a formal agreement between how both the server and the client side will interact allowing each component to evolve independently.
What Are The Few Major Implications Of Referential Transparency In Full Stack Development?
In backend development cycle referential transparency ensures that each function purely depends on its input parameters without any side effects.Adhering to functional purity in referential transparency allows outputs to be determined without relying on external state or mutable data.
Parallelization And Concurrency
Since referential transparency allows functions to be executed independently without any side effects, they can safely be run parallel or concurrently. Overall, this can improve performance in a multi-threaded or distributed system,
Caching and Memoization
Caching and memoization in full stack development involves optimization by storing and reusing computed results. Referential transparency ensures caching and memoization is highly effective by allowing the output to be cached based on the input values. It can be relied upon to return the cached result when the inputs remain the same, eliminating the need to recompute the result.
Popular Frameworks Utilized in Full Stack Development
Ruby On Rails
When you hire full stack developers, they must hold deep understanding working with one of the most popular web application frameworks also known as Rails. This framework adheres to the MVC pattern providing a productive environment to build full stack applications with fewer coding errors.
Django is a python based web framework that utilizes Model View Controller (MVC) architectural pattern leveraging a set of tools and libraries to build full stack applications. This framework is known for its simplicity and highly rapid development capabilities allowing developers to optimize their time-to-market rate.
