I have been through a lot of silicon valley interviews - too many software companies are run by people who think very highly of themselves and use interviews to torture prospects and see who survives. Workday actually wanted to get to know me, rather than torture me. Every step of the process was extremely friendly and professional.
Workday is looking for people who can think and are fun to work with, not recite methodology or show a pedigree of degrees and silicon valley brand names on your CV.
I knew I loved the company when this became evident during the interview process.
Joined a month ago and I love the company even more now that I am on the inside.
