Interview

Entry Level:

1. Technical Screening Round:

• Platforms: Phone or online coding platforms (HackerRank, LeetCode).

• Question types:

  • Basic algorithmic problems (sorting, searching, data structures).

  • Simple coding challenges using JavaScript fundamentals (arrays, objects, functions).

  • FrontEnd specific questions (DOM manipulation, basic HTML/CSS).

• Focus: Assess coding skills, problem-solving approach, and basic web development understanding.

2. Technical Interview Round (1-2 rounds):

• Platforms: Video calls, in-person interviews.

• Question types:

  • Frontend frameworks and libraries:

    • ReactJS: State management (Redux, Context API), props and state, lifecycle methods, component reusability.

    • Angular: Dependency injection, modules, routing, data binding.

    • Vue.js: Composition API, virtual DOM, reactivity.

  • JavaScript: Deep dive into core concepts (prototypes, closures, event loop), asynchronous programming (promises, async/await), and best practices (clean code, unit testing).

  • Web technologies: Advanced CSS (preprocessors, animations, layouts), browser developer tools, accessibility considerations.

  • Problem-solving: Live coding challenges simulating real-world scenarios, and white-boarding design solutions.

  • System Design:

• Focus: Assess practical skills with frameworks, deep understanding of JavaScript, problem-solving abilities, and ability to explain technical concepts.

3. Behavioral Interview Round (Optional):

• Question types:

  • Communication and collaboration skills.

  • Cultural fit and team dynamics.

  • Prioritization and time management strategies.

  • Approach to learning and staying updated in the field.

  • Ability to ask quality questions.

• Focus: Assess soft skills, communication abilities, team player mindset, and overall cultural fit.

Experienced/Senior Level:

1. Technical Screening Round:

• Question types:

  • Algorithmic problems with higher complexity (dynamic programming, graph algorithms).

  • System design concepts (high-level architecture, scalability).

  • Advanced JavaScript topics (functional programming, Web Workers).

• Focus: Assess higher-order thinking skills, ability to tackle complex problems, and initial exposure to system design.

2. Technical Interview Round (2-3 rounds):

• Question types:

  • Architecture and performance optimization: Caching strategies, code splitting, server-side rendering, browser optimizations.

  • Testing and debugging: Advanced unit testing frameworks, end-to-end testing methodologies, debugging complex issues.

  • State management and routing: Deep dive into Redux/NgRx/MobX/Context API, advanced routing techniques.

  • Browser APIs and advanced topics: Service Workers, PWAs, offline capabilities, WebAssembly.

  • Live coding: Coding out web components in the framework of your choice, some companies are specific in using one of their choice.

  • System design: Design and explain scalable architectures for complex web applications, and discuss trade-offs and considerations.

• Focus: Assess advanced technical skills, ability to design and optimize complex systems, problem-solving with real-world constraints, and strong understanding of browser internals and web APIs.

3. Behavioral Interview Round (Optional):

• Question types:

  • Leadership potential and ability to mentor junior developers.

  • Experience managing large and complex projects.

  • Communication and collaboration skills in a leadership role.

  • Conflict resolution and decision-making strategies.

• Focus: Assess leadership qualities, project management skills, and ability to work effectively in a senior role.

Additional Notes:

• Companies may place different weights on each round depending on their specific needs and the candidate's experience level.

• Some companies might have additional rounds like "Hacker Hours" or "Culture Fit" assessments.

• Be prepared to discuss your portfolio, personal projects, and contributions to open-source projects.

• Practice your communication skills and be able to articulate your thought process clearly.

• In recent times trend is that entry-level roles also require System Design knowledge so it's always better to have a decent knowledge of it.

• Asking questions in each round is essential to let the interviewer know about your interests.
