Workday Software Engineer interview experience: REST APIs and internship leadership

Technical Screen

The first step was meant to be a recruiter screen, but a technical staff member conducted it. I began with the usual behavioral introduction, and the conversation soon shifted into technical territory. They asked about my resume, REST APIs, and leadership examples from my most recent internship. Although the opening sounded as if it would be light, the later questions checked both how I communica…

Workday Account Executive interview: deal review and leadership interview

After a casual recruiter-to-hiring-manager conversation, I did a deal review with a panel. I walked through my sales experience and execution, turning my background into a clear account of what I had done and how I would drive outcomes. The next step was an interview with hiring leadership, which focused more on judgment and fit than on repeating those sales stories. The process followed a standa…

01

Going into the loop without having done this.

To maximize your chances of securing an offer at Workday, keep these practical, insider tips in mind:

02

Going into the loop without having done this.

Master UML Diagrams: Be ready to draw, explain, and defend UML class diagrams on a virtual whiteboard. Practice modeling everyday systems (like parking lots, libraries, or online shopping carts) and clearly defining class relationships, cardinality, and inheritance.

03

Going into the loop without having done this.

Communicate Your Thought Process: During coding and design rounds, do not work in silence. Talk through your assumptions, explain why you are choosing one data structure over another, and discuss the trade-offs of your approach.

04

Going into the loop without having done this.

Prepare STAR Stories for VIBE: Do not treat the behavioral questions as an afterthought. Prepare 3 to 4 detailed stories from your past experience that highlight your ability to collaborate, solve ambiguous problems, and promote an inclusive team environment.

Choose a category, try a prompt, then open its approach, worked solution or follow-up when you need it.

Coding & Data Structures

Implement a solution to parse and extract structured information from a raw resume file.

Approach
  1. Restate the input: its shape, its size, and what is guaranteed about it.
  2. Name the brute-force solution and its complexity before improving on it.
  3. Choose the data structure from the access pattern, not from familiarity.
  4. State the target complexity and say which constraint rules the naive version out.
Follow-up
  • How does this change if the input no longer fits in memory?
  • What is the worst case, and how likely is it on real data?

Given a series of inputs, implement a robust hashmap-based solution to find duplicate records efficiently.

PracHub preparation framework
How technical are the hiring manager rounds at Workday?

It varies by team, but the hiring manager round is typically a hybrid. Expect a mix of high-level architectural discussions, questions about your past technical projects, and a deep dive into your behavioral and cultural alignment. Some managers may also ask abstract object-oriented design questions during this conversation.
