Frontend Engineer | Zeta | Hyd - Zeta

Summary

I had a good interview experience for a FrontEnd Engineer role at ZETA, which included three specific coding questions focusing on JavaScript fundamentals, memoization, and implementing an Undo/Redo functionality within 60 minutes.

Full Experience

Round 1

What would be the output of below code snippet

console.log(1)
const promise = new Promise((resolve) => {
console.log(2)
resolve()
console.log(3)
})
console.log(4)
promise.then(() => {
console.log(5)
}).then(() => {
console.log(6)
})
console.log(7)
setTimeout(() => {
console.log(8)
}, 10)
setTimeout(() => {
console.log(9)
}, 0)

Implement Memoize funcion. Run it with input of different datatypes
Implement a JS class HistoryManager that mimics Undo/Redo functionality

Need to complete all the questions within 60 minutes.
