After receiving two very easy interviews, which seemed to both go exceedingly well, each of which lasted about an hour, I was ghosted, even after numerous attempts to follow up with not only the HR rep, but the environment lead. At least have the common decency and professionalism to send a rejection letter. Ghosting is extremely unprofessional and the cowardly way out for a seemingly professional establishment. Is this really how you treat people who make the effort to apply and contribute to your cause? This is how you repay them?
