Tekion Frontend Interview Experience — Offer Declined 🚀

Overview

This document details a frontend engineer's interview experience with Tekion for the Software Engineer II position. The evaluation process encompassed a range of technical domains, including data structures and algorithms (DSA), low-level design (LLD), high-level design (HLD), and a hiring manager (HM) discussion.

Interview Rounds

The interview process was structured into four distinct rounds:

Round 1: Data Structures and Algorithms (DSA)

This round assessed the candidate's problem-solving abilities using JavaScript. The questions included:

1. Polyfill for Bind Method: The candidate was required to implement a custom polyfill for the bind() method.

   const obj = {
       name: 'Gourav',
       methodOne: function() {
           console.log('method1 Running')
       }
   }
   
   obj.methodOne()
   
   function test(age) {
       console.log(this.name, age)
   }
   
   Function.prototype.myBind = function (thisContext, ...argsArray) {
       let parentFunction = this;
       return function bindedFun(...funArgs) {
           return parentFunction.apply(
               thisContext, [...argsArray, ...funArgs]
           );
       }
   }
   
   let bindedFunc = test.myBind(obj);
   bindedFunc(29);
   

2. Currying Function Implementation: The candidate was asked to implement a currying function that could be invoked partially.

   function curry(func) {
     return function myCurried(...args) {
         if (args.length >= func.length) {
             return func(...args);
         } else {
             return (...args2) => myCurried(...args, ...args2);
         }
     };
   }
   
   function test(a, b, c) {
     return a + b + c;
   }
   
   const curriedFunction = curry(test);
   console.log(curriedFunction(1, 2, 3)); // 6
   console.log(curriedFunction(1, 2)(3)); // 6
   console.log(curriedFunction(1)(2)(3)); // 6
   

3. Machine Coding: Stopwatch: The task was to implement a Stopwatch component with functionalities for Pause, Play, Stop, and Reset.

Round 2: Low-Level Design (LLD)

1. Machine Coding: Word Guess Game: The candidate was tasked with implementing a Word Guess game similar to Wordle.

   • Follow-up Questions:
     • How would you handle errors and success cases?
     • How do we optimize performance and make it scalable?
     • How would you design the keyboard functionality?
