React Coding Interview Questions on Hooks and Context API

React has become extremely popular, as a JavaScript library for creating user interfaces. As Reacts popularity continues to soar frontend developer interviews often include react interview questions related to React to assess a candidate's coding skills.

React Hooks and Context API are relatively advanced React concepts that development teams want senior candidates to demonstrate expertise in. This blog discusses the top React coding questions on Hooks and Context that experienced React devs should prepare for. Read on to get an overview of the key concepts tested in React interviews, sample code snippets, and online editor links to practice.

1. What Are React Hooks and Why Are They Used?

With the introduction of React Hooks, in version 16.8 you can now use state and other React features without having to write class components. These hooks greatly simplify state management in components, making the code more understandable and facilitating testing. Hooks provide a mechanism to share stateful logic across different components without changing the hierarchy of the components. It is important to understand hooks to create modern React applications.

2. Explain the useState Hook in React.

The useState hook is the foundation of state management in functional components. It allows you to inject React state into function components. When you declare a state variable with useState, you receive a pair: the current state value and a function for updating it. The underlying principle of how useState works is essential to comprehend state management in functional components.

3. How Does useEffect Hook Work?

In functional components, side effects are performed through the useEffect hook. The functionality is similar to componentDidMount, componentDidUpdate, and componentWillUnmount in React class lifecycle methods, but it is unified with one API. Managing side effects like data fetching, subscriptions, or manually updating the DOM from React components is impossible without first understanding useEffect.

4. What is the useContext Hook and Its Use Cases?

UseContext hook is a way of creating common data that is accessible at any level of the component hierarchy without the necessity of passing the props manually to each level. It’s used to communicate data such as user authentication, themes or language preference between components seamlessly. Understanding useContext is vital for effectively controlling data and communication between components in large React applications.

5. Can You Explain Custom Hooks?

Custom Hooks refer to the mechanism to reuse stateful logic in several components. They enable you to pull component logic into functions that can be reused. A custom Hook is a JavaScript function whose name starts with ”use�� and can call other Hooks. Knowing how to make and use Custom Hooks can significantly reduce the complexity of your component logic and make your code more maintainable.

CHIA SẺ KINH NGHIỆM TÌM VIỆC IT Ở PHẦN LAN - Part 2

Sau bài viết thứ nhất, mình chưa quyết định viết ngay phần hai vì mình muốn dành một vài ngày để đọc kỹ lại rồi chỉnh sửa câu cú ngữ pháp và để đảm bảo rằng mình đã chia sẻ hết tất cả nội dung mình mong muốn cho các bước (cơ bản) ban đầu trên hành trình tìm việc ở Phần Lan. Nếu bạn chưa đọc nó, bạn có thể ngó qua ở đây.

Như có nói ở phần một, kinh nghiệm làm việc thực tế là một trong những yếu tố quyết định giúp bạn pass CV scanning. Với các bạn sinh viên mới ra trường, các bạn có thể bù đắp các yêu cầu kinh nghiệm làm việc thực tế này bằng cách tham gia các project ở trường, Demola, hay các side projects của chính bạn. Hầu hết các công ty vẫn đều rất xem trọng các kinh nghiệm thực tiễn này và xem nó là một trong những yếu tố quyết định họ có nên tiếp tục process với bạn hay không.

Vậy sau khi họ quyết định tiếp tục process với bạn thì các bước/vòng đó sẽ được thực hiện như thế nào, nội dung các vòng phỏng vấn đó là gì, mình nên chuẩn bị như thế nào cho tốt,… Các câu hỏi trên mình sẽ cố gắng chia sẻ hết dựa theo kinh nghiệm của bản thân. Và một lần nữa, mình xin nhắc lại, tất cả các chia sẻ này chỉ dựa vào kinh nghiệm và quan điểm của cá nhân mình, nó không hoàn toàn đúng, do đó bạn chỉ nên dùng nó như một sự tham khảo.

1. Phone / F2F scanning interview:

Chắc nhiều bạn sẽ thắc mắc tại sao lại có scanning interview sau khi đã scanning CV. Thực ra vòng này chỉ có ở một số công ty lớn có nhiều ứng viên ứng tuyển hoặc muốn chắc chắn rằng ứng viên thực sự match với yêu cầu của họ.

Vòng phỏng vấn này thường được thực hiện qua điện thoại cùng với HR, thời gian dao động từ 15 phút – 1 tiếng. Nội dung bao gồm:

Đầu tiên họ sẽ giới thiệu sơ về công ty, về vị trí bạn đang ứng tuyển, về các benefit mà công ty offer,…

Tiếp theo, họ sẽ yêu cầu bạn giới thiệu sơ về bản thân bạn. Câu hỏi này thường rất chung chung, nhưng thực sự, cái mà họ quan tâm chỉ những thông tin liên quan tới vị trí họ đang cần tuyển. Ví dụ, để tuyển cho vị trí web developer, và công ty yêu cầu biết ReactJS / Webpack… Họ sẽ quan tâm tới các kiến thức bạn có, các kinh nghiệm liên quan, các dự án bạn đã làm, ở công ty nào, và vai trò của bạn là gì. Thường bạn chỉ nên đưa ra các thông tin cơ bản nhất, không nên quá chi tiết và dài dòng. Nếu họ quan tâm họ sẽ hỏi thêm.

Từ những thông tin bạn chia sẻ, cùng với các yêu cầu tuyển dụng. Họ sẽ có thêm một vài câu hỏi và trao đổi với bạn.

Qua vòng phỏng vấn này, một lần nữa, HR sẽ kiểm tra và xác định thêm một lần nữa, bạn match với yêu cầu của họ.

2. Introductory interview

Vòng phỏng vấn này, thường họ sẽ mời bạn tới office của công ty để thực hiện. Thời gian thường hơn từ 1–2 tiếng. Mục đích của vòng phòng vấn này chủ yếu là giới thiệu về công ty, vị trí tuyển dụng cũng như tìm hiểu kỹ hơn về kinh nghiệm làm việc tổng quát.

Sau khi giới thiệu về bản thân và kinh nghiệm làm việc, bạn sẽ được hỏi về các công nghệ, các kỹ năng mà công ty yêu cầu:

Bạn đã làm việc với công nghệ này chưa? Những dự án nào? Vai trò của bạn trong dự án đó là gì? Với câu hỏi này bạn nên trả lời đúng trọng tâm của câu hỏi, có hoặc không, có thì kể ra một số dự án, mô tả sơ về dự án, vai trò của bạn trong dự án đó. Nếu không có kinh nghiệm làm việc với nó thì bạn có biết về công nghệ đó không? Biết ở mức độ nào? Bạn tự tin bao nhiêu phần trăm là mình có thể làm việc với nó… Trả lời một cách rõ ràng ngắn gọn, đừng dài dòng, và tìm cách trả lời một cách gợi mở để hướng người phỏng vấn hỏi những câu mà mình mong muốn họ hỏi mình. Với cách này bạn có thể dẫn dắt cuộc phỏng vấn theo ý bạn và có cơ hội thể hiện bản thân nhiều hơn.

Bạn thích làm việc một mình hay làm việc với team hơn? Bạn có phải là một team player không?   Đây cũng là một câu hỏi mình thường gặp khi đi phỏng vấn. Thật lòng, mình không biết họ mong chờ và đánh giá một câu trả lời tốt như thế nào. Tuy nhiên, theo mình nghĩ, với câu hỏi này, mình nên trả lời sao cho thể hiện được 2 điểm sau. Thứ 1, khả năng làm việc độc lập của mình, không phụ thuộc, hay cần quá nhiều mentorship,… Thứ 2, mình cũng phải là một team player, có thể làm việc tốt với người khác như thế nào, khả năng làm việc nhóm của mình ra sao,…

Agile practices & working methodologies (Scrum / Kanban / XP) Mỗi công ty có 1 process, một phương pháp làm việc khác nhau, vậy nên các công ty sẽ có thể hỏi hoặc không các kinh nghiệm hay kiến thức liên quan tới Agile/Scrum. Tuy nhiên, 90% công ty mình đã từng tham gia phỏng vấn, họ đều hỏi các câu hỏi liên quan tới Agile (Scrum/Kanban). Nếu bạn không có kiến thức hay kinh nghiệm về Agile bạn có thể tìm đọc thêm.

Một số câu hỏi khác bạn có thể tham khảo ở đây hay hỏi thêm bác Google.

3. Technical Interviews

Vì bản thân mình làm Software Developer nên phần này chỉ có thể chia sẻ các kinh nghiệm phỏng vấn dành riêng cho Software Developer. Nếu bạn theo một hướng khác, bạn có thể đọc tham khảo nhưng mình không chắc nó sẽ giúp ích được nhiều cho bạn.

Như nói ở trên, mỗi công ty có 1 quy trình tuyển dụng riêng nên cách thức phỏng vấn, đánh giá cũng có nhiều điểm khác nhau. Sau đây là một vài technical interviews mà mình đã tham gia.

a, Whiteboard / Paper coding challenge:

Bạn sẽ được cho 1 vài bài tập (challenges) và họ sẽ yêu cầu bạn viết code trên bảng hoặc giấy để giải quyết bài tập đó. Mục đích của việc này không phải để kiểm tra kỹ năng code mà là khả năng problem solving và communication của bạn:

Cách bạn tiếp cận vấn đề.

Cách bạn giải quyết vấn đề.

Cách bạn trình bày / giao tiếp / giải thích vấn đề và hướng giải quyết với người khác.

Kinh nghiệm của bạn thân mình cho vòng phỏng vấn này đó là:

Xác định vấn đề là gì? Thường interviewer sẽ cho giải thích cái problem là gì, cùng với đó là một vài samples (các bộ input và output). Từ đó mình sẽ có thể xác định được vấn đề cần giải quyết.

Tìm hướng giải quyết? Việc đầu tiên cần nhớ trước khi bắt đầu đó là, đừng mất quá nhiều thời gian để tìm ra phương án hoàn hảo. Vì có thể, khi thời gian đã hết, bạn vẫn không thể viết ra được dòng code nào. (Điều này tương tự với khi bạn làm việc, khi mà deadline đang dí thì bạn sẽ không bao giờ có đủ thời gian để viết code tối ưu hay hoàn hảo). Hãy bắt đầu với từng sample, và viết code để từ input này ra được đúng output mong muốn. Ví dụ: - Step 1: Từ input1 để ra được output1 mình viết ra function A1 - Step 2: Thay input 2 vào, kiểm tra kết quả có phải là output2 hay không. Nếu không thực hiện chỉnh sửa để cho output2 mà vẫn giữ được input1 cho output1. … - Cứ tiếp tục như vậy thử và chỉnh sửa code để đáp ứng thoả mãn được các sample cho sẵn. - Sau khi thử hết các sample có sẵn, tìm các unhappy cases, tự đưa ra các sample cho các unhappy case đó và đưa vào kiểm tra code của mình có chạy đúng không. Nếu không chỉnh sửa. - Cuối cùng, đọc lại toàn bộ code, tìm cách optimize nó.

Giao tiếp và trình bày? Trong quá trình tìm hướng giải quyết, theo kinh nghiệm của bản thân, bạn nên nói rõ ràng, trình bày, giải thích những gì bạn đang nghĩ trong đầu, ví dụ như: có các trường hợp nào xảy ra, nếu mình làm như vậy thì kết quả sẽ là gì, có vấn đề gì hay không,… Với cách thức này, ngoài việc cho thấy khả năng giao tiếp cũng như trình bày, thảo luận của bạn ra sao trong khi làm việc, đôi khi, bạn sẽ được có thêm hints từ interviewers, hay các nhận xét từ interviewers để hoàn thành challenge một cách tốt hơn.

b, Q&A challenge:

Đây là phần hầu như công ty nào cũng có. Các câu hỏi đưa ra sẽ xoay quanh tới các skills mà vị trí tuyển dụng yêu cầu:

Như frontend developer sẽ được hỏi các câu hỏi liên quan tới HTML/CSS, Javascript, ReactJS, Angular, Webpack, REST API,…. hay các câu hỏi advanced hơn như liên quan tới loading time optimization,…

Như mobile developer (iOS) sẽ được hỏi các câu hỏi liên quan tới Objective-C, Swift, iOS SDK, ViewController life cycle, Unit Test, UITest, CI, CD,…

…

Các câu hỏi này bạn có thể tìm thấy trên Google rất nhiều. https://lmgtfy.com/?q=interview+questions+for+mobile+developer https://lmgtfy.com/?q=frontend+interview+questions

Cách duy nhất để bạn có thể trả lời tốt cho các câu hỏi này đó là làm thật nhiều và khi làm, bạn cần hiểu và nắm rõ ngôn ngữ lập trình bạn dùng, framework và platform bạn làm việc với. Sau đó google các bộ câu hỏi phỏng vấn cho vị trí bạn nhắm tới, đọc câu hỏi, tham khảo câu trả lời. Cố gắng đảm bảo mình hiểu 100% câu trả lời. Tránh việc học thuộc, học vẹt :).

c, Assignment:

Hình thức kiểm tra này rất phổ biến ở Phần Lan, hồi ở Việt Nam, khi mình đi phỏng vấn xin việc, chỉ có 1 công ty duy nhất yêu cầu mình làm assignment trong 6 năm đi làm. Hầu hết, các công ty chỉ có whiteboard coding challenge và dạng Q&A mà thôi.

Các công ty sẽ yêu cầu bạn thực hiện 1 application nhỏ, web app (nếu vị trí bạn apply là web developer), mobile app (nếu bạn apply iOS / Android / mobile developer), web service/API (backend developer),…

Khi bạn nhận được yêu cầu, chú ý đọc kỹ yêu cầu, hiểu rõ công việc cần làm là gì. Ngôn ngữ nào, công nghệ gì,… Có yêu cầu gì đặc biệt hay không. Thường, các công ty sẽ không có quá nhiều yêu cầu đặc biệt và để bạn tuỳ chọn từ công nghệ đến thiết kế giao diện,….

Ok, vậy khi mình thực hiện assignment này, mình cần chú ý những gì:

Tránh đâm đầu vào code ngay, rất dễ dẫn tới việc code một nùi xong phát hiện ra mình hiểu sai vấn đề và làm lại từ đầu. Cố gắng, đọc kỹ yêu cầu, xác định các feature cần có của application mình làm.

Thiết kế cơ bản cho app của mình, bao gồm thiết kế giao diện nếu là web app hay mobile app, trường hợp là API thì nên tìm hiểu kỹ API của mình nhận params gì và trả về response gì, thiết kế JSON schema,…

Chọn architecture & design pattern mình sẽ follow. Đây là một trong những yếu tố quyết định bạn có pass được vòng này hay không. Thường các công ty sẽ cho bạn tuỳ chọn và không ràng buộc bạn theo architecture hay design patteren nào. Nhưng theo kinh nghiệm của bản thân, nếu trong job description có yêu cầu biết design pattern nào đó, thì bạn nên dùng nó, đó sẽ là một điểm cộng cho bạn.

Sử dụng version control system. Hầu hết các công ty mình đã phỏng vấn ở Phần Lan xài GIT. Và thường khi cho yêu cầu assignment, họ sẽ cung cấp cho bạn 1 repository để bạn push code lên. Nếu không, bạn nên tạo 1 private repository ở Github hoặc Gitlab để quản lý code của bạn và submit khi hoàn thành xong. Việc không sử dụng hoặc sử dụng Version Control không đúng cách sẽ là một điểm trừ khi team work. Vậy nên, bạn nên chú ý việc sử dụng cho đúng (như chia nhỏ các commit, commit có message rõ ràng, commit thường xuyên,…). Bạn có thể tham khảo thêm ở link sau.

Trong quá trình code, chú ý follow các coding best practices, follow coding standards & guideline mà community xài, follow các principles (như S.O.L.I.D),…

Sẽ là muốn điểm cộng lớn nếu bạn có Unit Test để cover cho các function của bạn.

Tạo README file, giải thích cách cài đặt, cách run application của bạn. Mô tả sơ về architecture, các libraries bạn sử dụng, lý do tại sao.
