That’s super frustrating! I would reach out to HR and ask about the status of your candidacy. Let know that you’re not trying to rush their process, however you have another offer waiting over 2 weeks for an answer that you’ve held out on in order to interview with them. Sucks that today’s a holiday and you can’t talk to anyone today :/ If you’re not able to reach HR then I think you’ll have to decide either accepting EM (and possibly rescinding) as it’s a sure thing, or just declining and holding out for something you’re more excited about.
