Interview Rounds

The Spinny interview process was structured into three distinct rounds:

Round 1: JS Basics (Screening Round - InterviewVector)

This round, conducted by InterviewVector, concentrated on evaluating the candidate's grasp of fundamental frontend concepts and live coding abilities using HTML and JavaScript. The panel was reported to be friendly, creating a positive interview environment.

• Question 1: The candidate was asked to construct an HTML structure for a basic UI incorporating a search input field.
• Question 2: The candidate was challenged to implement search suggestions via API calls triggered by input changes. This included practical application of:
  • Debounce Function: To manage the frequency of API calls.
  • Closure: Demonstrating understanding of scope and variable persistence.
  • Polyfill: Showing awareness of cross-browser compatibility and feature support.

The candidate was also asked to implement the following function:

function sum(...init) {
  let total = init.reduce((a, b) => a + Number(b || 0), 0);

  function next(...args) {
    if (args.length === 0) return total;        
    // empty call ends the chain
    total += args.reduce((a, b) => a + Number(b || 0), 0);

    // keep chaining
    return next;                                 
  }

  return next;
}

// Examples:
console.log(sum(1)(2)(3)());        // 6
console.log(sum(5)());              // 5
console.log(sum()());               // 0
