Talked to a former colleague who worked at Workday at my university's career fair in January. I initially told him I wasn't going to talk to any of the people in charge there because I had already didn't advance past 1st round interviews in November, but he told me it was worth a shot. That evening I got a phone call asking if I'd like to take part in an on campus interview the following morning, which I agreed to. This initial interview was heavy on UML type questions, and class interactions, and then followed up by a traditional programming question.
Two weeks later I get an email asking if I'd like to participate in final round interviews onsite. You have to make all the travel arrangements by yourself, but the recruiter in charge of all the expenses was very helpful and quick.
Two weeks after that, was the day of the interview. They start early, a little before 8 o'clock. They give you breakfast (bagels, yum), make you introduce yourself to everyone, and then give an overview of how the day will go. Because I was interviewing for the App Dev position, they took the other 4 of us interviewing for it to a conference room to show us the language and how it works. There was a little bit of an issue with the internet, but it answered a lot of questions I had about their propriety language, and they discuss why they use it. From there, we were rushed into individual rooms to be interviewed for 4 straight hours.
Luckily, these interviews are pretty short (most are 30 minutes, others are 15) and you mostly discuss the projects you've done, your goals and ambitions, and what interests you about Workday. I don't know if it's common, but one of the 30 minute interviews was psuedo-technical, and the interviewer asked what divide-and-conquer algorithms I knew, and the complexity of them. Everyone was ridiculously friendly, and didn't suffer from the know-it-all attitude I've had interviewing with other companies. The technical question was an hour long, and and more class diagram stuff, which wasn't too bad, but I did freeze up a little near the end. This was also followed up with a small psudeocode programming challenge.
After the interviews, they feed you lunch, and then demo the product and the language, and allow everyone to participate. After two hours of that, they discuss benefits and then let you go on your merry way.
One week after that, I got a phone call from my recruiter offering me the position. Couldn't be happier!
