I was ghosted after completing six rounds of interviews and a 'homework assignment' that took about 10 hours. Of all the companies I interviewed with last year, this was by far the most horrible and demoralizing experience. Shortly after, I was hired by a wonderful company that actually seemed to care about their candidate experience. But I tell everyone who will listen not to apply here, unless you enjoy putting dozens of hours into a process that won't even give you the courtesy of a canned rejection email.
