The post Coruscate Monthly Celebration Broadcast (Episode: 3) – Our New-Year’s Resolution – WORK IN A TEAM TO ACHIEVE IN BULK! appeared first on Coruscate Solutions.

This famous quote is the reason why we always have professional and personal achievements to celebrate. Coruscate is the people-driven company where every employee and business partners work together and discover their roles to solve deep-rooted problems. Their roles aren’t always the same, but their goal always remains the same – engineer a software and mobile app which improve the lives of people.  

Encouraging transparency, think long-term, learn and teach, share the pain, take responsibilities of everything, and focus on results and getting better are the core values of us as Coruscate. Which indirectly lead us to success for customers and success for us.

In the last 15 days (1 December 2019 to 15 December 2019), we did justice with our 3 out of 6 values in the best possible ways.

We arranged a week-long recruitment drive to strengthen our team and to get better. We thought long term and ordered our first ever smart e-scooter to conquer the micro-mobility industry more aggressively. And one of our team members got selected as the lead speaker at the Flutter Extended and Viewing Party event to share his already earned knowledge with other people.  

 So, in this first blog of the ‘Company Insights’ series, let’s discuss the cause, execution and outcome of our 3 major achievements of the last 15 days.

Following are 3 things Coruscate, a top IT company in Surat, has achieved in the last 15 days

A week-long recruitment drive at the top IT company in Surat 

(Cause) Coruscate is made out of vision and people. And we have the vision but to satisfy that vision we were lacking the people until 7 December 2019! Because, from 8 December 2019 to 15 December 2019, we organized walk-in interviews as well as off-campus drive for the local talents to be part of our company and work with global clients.

(Execution) For off-campus drive, we worked with two well-known universities of our locality named SSASIT and Auro University and welcomed 20 candidates from these two colleges. On arrival, we greeted them and made them aware of our company values, vision, cultural and course of actions. To evaluate their technical knowledge as well as thinking and reasoning skills, we conducted a written test. Candidates who scored above the threshold were later sent for the panel interview. Before the panel interviews, we offered lunch to all 20 candidates and then distributed interview results to each candidate. Interview reports of the candidates who didn’t get selected for panel interview or failed to impress our panel were shared verbally with the reasons so that they can know their limitations and work on it to secure a much better job in future.

Talking about the walk-in drive, it was our first time when we decided to let any candidate come at Coruscate at his preferred time and we must mention that it was our best decision! Initially, we were thinking of only one day, but considering current open positions we experimented the walk-in drive to 7 days. During those 7 days, we tried our best to spread the knowledge of this opportunity among the local talents. For that, we promoted it on several social media platforms.

(Result) In these 15 days, we took the interviews of 50+ candidates (Walk-in and other prospects) for various technologies & positions and hired 7 new employees (2 Business Analyst, 1 HR Generalist, 1 DevOps Engineer, 1 Android Developer, 1 MERN Stack developer).

Apart from that, we welcomed 12 interns (Flutter developer, MERN Stack developer, AI scientist) and 3 Employees (2 MERN Stack developer and 1 Content Writer) to our family.

(Happy faces of candidates reveal all!)

Receiving our first ever smart e-scooter at the doorstep of Coruscate  

 (Cause) We are the early player in the micro-mobility industry and we are making people fond of watts. In the last two years, during the rapid economic growth of the micro-mobility industry, we have worked with many e-scooter rental startups and developed many e-scooter apps. But we always faced a problem to push the boundaries of e-scooter hardware using e-scooter software as we did not have own e-scooter which we could use only for research purposes.    

(Execution) When a few developers and team leaders forwarded this problem to the management team of the Coruscate, they took it into account and surprised those developers and team leaders with the new smart e-scooter, imported all the way from Malaysia. This action of our management team clearly depicts that regardless of the cost of the resource, they make it available for the developers who really want to get some hands-on experience which is, by the way, beneficial for the future of the company as well as for the future of the developers.

(Result) A few IoT engineers and developers have been understanding the technical functionalities of IoT controller of that e-scooter and exploring possible ways to make that e-scooter work beyond expectation since we have received it at Coruscate, a top IT company in Surat. Looking at their countless efforts, it seems like they will soon come up with a very groundbreaking discovery.  

Our Commander, Sandip, is ready to give his first public speech

At Coruscate, we have successfully created a work environment where employees can cultivate many other skills rather than just technical skills. Public speaking is one of them. Our one of the very well-versed developers got selected as the lead speaker at the Flutter Extended and Viewing Party event which is going to be held in Surat on 22 December 2019.

Sandip has a total of 3.5 years of experience in the IT industry and since the past one year, he has been working in the Flutter team as the Manager. The only reason why Sandip got selected as the lead speaker is because of his expertise in Flutter app development. In fact, he is the best Flutter developer we have at Coruscate.  

In this Flutter event which is organized by Google Developer Group, Sandip is going to share his earned knowledge about ‘app optimizing using Flutter’. Also, Coruscate is a venue partner for this event and event is going to be organized at our Surat office.

There was a time when developers didn’t have more options to design an appealing interface of the app. But as users started selecting the app based on its UI and user experience, app owners started asking app development companies to satisfy users’ needs in the best possible way. 

Facebook launched React.Js in 2013 and it was the aftermath of rising demand for the very easy and efficient development technology to build user interfaces of mobile apps without fighting an uphill battle. Currently, all mobile app development companies are using React.Js to build interacting and flashy UI of mobile apps. And for that, they are actively hiring more and more React.Js developers. 

What is React.Js?  

React.Js is the JavaScript library which is very purposeful to build user interfaces of mobile apps. It was launched by Facebook and a community of individual developers and companies. 

Not only mobile app, but React.Js can also be useful to develop Single-Page-Application. React.Js is the best choice when there is a requirement to fetch rapidly changing data that needs to be recorded. Components are the key elements of the React.Js. A Component is nothing but the self-contained module which renders output. A developer can easily write the code of button and input field as the Components. 

Let’s understand the use of Components through an example. 

Suppose, you want to build a form using React.Js. For that, you have to write each interface element like input field, label or button as the React.Js components. Not only this but you also have to write the higher-level components which define the structure of the form itself. And these higher-level components contain the already written components of the input field, label or button. 

The popularity of React.Js and market demand for React.Js developers 

The following image depicts that the popularity of React.Js has skyrocketed in recent times and even surpassed its biggest rival, Angular.Js. 

As an upshot of the rising popularity of the React.Js, market demand for React.Js developers is also increasing. Refer the following image to know how easily a React.Js developer can secure a good job. 

Frequently asked React.Js interview questions and answers 

The following are the most frequently asked React.Js interview questions and answers which you should read before entering the interview room. 

Question 1: What are the differences between React.Js and Angular.Js? 

Answer: 

• Angular is the framework, while React.Js is the JavaScript library. 
• To update the Real DOM (Document Object Model), Angular uses two-directional data flow process. Whereas, React.Js updates virtual DOM and uses only one-directional data flow message. 
• React can be used along with other programming libraries. Angular doesn’t depend on other programming libraries as it is the complete solution itself. 
• Angular.Js can delay project delivery as the code of it is a bit complex. 

Question 2: What is the life-cycle of the React.Js components? 

Answer: 

A Component has two types. One is the High-Level Component and the other is the Low-Level Component. 

High-Level Component Life Cycle: 

• Initialization
• State/Property Updates
• Destruction

Low-Level Component Life Cycle: 

• Initialization 
• Update 
• Destruction 

Question 3: What is the Flux? 

Answer: 

Flux is the architectural pattern that enables unidirectional data flow. When we use Flux, multiple components can interact with derived data at the same time. However, Flux is the generic pattern and it is not specific to React Applications.

Question 4: What is the use of Keys in React.Js? 

Answer: 

To find out unique VDOM Elements with their corresponding data, Keys are used. 

Question 5: What is the use of refs in React.Js? 

Answer: 

As <li ref=“XYZ”/>, Ref is generally added to an attribute React.createElement(). The ref is useful to get simple access to DOM Element which is represented by React Element. 

Question 6: List out some limitations of React.Js. 

Answer: 

• React.Js is not a framework (a whole ecosystem), but it is just JavaScript Library.
• The Library of React.Js is large and complex. 
• Google and other search engines can’t index React.Js application properly. 
• React.Js comes with poor documentation. 

Question 7: What is JSX?  

Answer:

JSX stands for JavaScript XML and it allows developers to write HTML in React.Js. It converts HTML tags into elements of React.Js. When developers use JSX, they don’t have to use createElement() and appendChild() methods to place HTML elements in DOM. 

With JSX: 

const myelement = <h1>I Love JSX!</h1>;

ReactDOM.render(myelement, document.getElementById(‘root’));

Without JSX: 

const myelement = React.createElement(‘h1’, {}, ‘I do not use JSX!’);

ReactDOM.render(myelement, document.getElementById(‘root’));

Question 8: What are the Props in React.Js? 

Answer: 

Props in React.Js are nothing but properties that are read-only components. These Props components are always passed down from parents to child components. With this, we can maintain a unidirectional data flow. 

Question 9: How to modularize code in React.Js? 

Answer: A code is called modular when it is separated into different modules. In React.Js, we can modularize the code by using two properties – export and import. 

Question 10: If we hire you, for which purposes you will use React.Js and why? 

Answer: 

React.Js is very serviceable to build UI of the mobile app. However, we can also use React.Js to develop a dynamic page that rewrites the current page rather than loading the entire page from the server. 

There are many reasons to use React.Js. High productivity, easy maintenance, faster rendering, helpful developer toolset, and stable code are the main reasons.
