Interview Process Overview

Usually, the interview process for the Software engineer role at Workday consists of 3-4 rounds:

  • Recruiter Screen
  • HackerRank online test
  • Phone Screen
  • Onsite Round 

Here's a more detailed description of the interview process:

Recruiter Screen

Overview

The recruiter screen is a 30-minute interview with the recruiter. This is an exercise to primarily assess if your experience and skill sets are a good match for the job. Many questions in the Recruiter screen are based on your previous experience/resume. So, make it a point to be thoroughly prepared with your resume. Keep your answers short, crisp, and structured. Interviewers may also be interested in knowing your motivation for the role. So, rehearse some of the most commonly asked questions, such as "Why do you want to work for Workday?"

HackerRank Online test

Overview

After the recruiter screen, you will be facing a technical online test on the HackerRank platform. This is a timed test consisting of 3 medium-difficulty coding questions to be completed in 120 minutes. The online test consisted of 3 problems, one in Java, one in SQL, and one in JavaScript.

Interview Questions

  • Write a code to perform Breadth First Search (BFS) traversal of a 2-d matrix with memoization to find the shortest weighted path."
  • Given a String of [a-z, A-Z, 0-9], find the length of the longest substring that satisfies the following rules: a substring cannot contain digits [0-9], a substring should contain at least one capital character [A-Z]. e.g., given the String "aqW9ertyz", the longest valid substring has length 3 ("aqW").

Phone Screen

Overview

Next up is the Phone screen. The phone screen is a telephonic interview round with a Workday Hiring Manager. This interview will last for about 45 minutes. The interviewer may ask a few technical questions and discuss the job responsibilities of the current role. Questions in this round are going to be theoretical and conceptual. So, revise your fundamentals well. Focus on Coding, especially OOPS concepts and system design questions.

Interview Questions

  • Can you call the base class method without creating an instance?
  • What do you understand by method overloading?
  • What is the difference between OOPS and Procedural programming?
  • What do you know about load balancing? What is its importance in system design?
  • Explain the steps involved in incorporating microservices into an e-commerce platform.
  • How would you determine the goal and scale of a system?
  • What do you understand by Polymorphism?

Onsite round

Overview

After clearing the phone screen, the next round is the onsite round. The onsite round is the most complicated stage of the entire interview process. You will spend roughly 7 hours on the interview day facing multiple interviews. The onsite round consists of a total of 3 interviews as under: 

  • Coding interview
  • System Design interview
  • Behavioral interview

Coding interview

The coding interview will involve writing code, debugging a given piece of code, and algorithms. The choice of language is up to the candidate, but interviewers prefer candidates well-versed in common programming languages such as C, C++, and Python.

System design interview

System design interview involves situational questions wherein you are asked to design the frontend/backend of apps, websites, etc. You may also be asked questions on scalability, multithreading, distributed systems, and Unified Modeling Language (UML) diagrams.
