HMH Education Full Stack Developer interview questions

I had a phone call with a recruiter, then with a dev manager, followed by a 4 hour inperson interview with several devs/manager/director. The director told me I should hear back from them within two days about their decision. Never heard back from them. I tried to follow up with the recruiter to get feedback but that also went nowhere. I came in from out of town for such a long interview and didn't even get a rejection email. Clearly they don't care for or value people's time. Wouldn't recommend to anyone.
