Fucking Workday. I hate them so much. I'm applying for jobs right and left right now and half of them use Workday as a job application system and Workday is so shitty that you have to register individual accounts for half of the job applications but can re-use one you created elsewhere for the other half. And it's not even clear when that is necessary to do until after you try to log in and are rejected.
That is some supremely shitty coding. Either that or some sort of intentional thing that I cannot fathom.
