I applied online for an Applications Engineer role, and within a few days, the recruiter set up an initial phone screen. Nothing was out of the ordinary on this call, other than a brief question about an OOP example. It was pretty straightforward.

About a week later, I had an hour-long interview with the hiring manager for the given requisition. This was split into a behavioral and technical portion over a video chat. The behavioral portion was very conversational and pleasant. The technical portion involved an OOP exercise using UML class diagrams. Basically, I was given a UML diagram representing some system and asked to find ways to improve it.

About a week after that, I had a virtual onsite. This onsite consisted of a total of 6 interviews, of which 2 were technical. I met various members of the team and organization. The behavioral interviews featured standard questions, again in a conversational format.

Of the two technical interviews:

• One was a shared-screen UML class diagram exercise where, given some requirements, I had to design a system.
• The other technical interview was a coding round (unexpected, as other Glassdoor experiences indicated there wouldn't be any) about finding the longest distance to a leaf on a binary tree given some node.

Interview feedback was provided within 3 business days. I was told they went in a different direction based on technical needs, which wasn't a huge surprise since I hadn't used UML until I started prepping for this interview, and I certainly wasn't expecting a coding question.

Overall, the process was good, even though I didn't make it through. Big thanks to the recruiter for keeping me well updated and acting promptly for each subsequent interview step. Everyone I spoke to was really kind, and it made me appreciate the company's culture. However, I did get the vibe that Workday recruits and puts together teams of people from very similar academic backgrounds, which certainly doesn't help with diversifying teams.
