long and you have to do a project and present the courseware to the hiring team - role play just like you're talking to an instructor or a committee at a school

I had the first round of interviews where one manager was on and if you "passed" you the next manager came on about 1/2 way through to finish. Here's what's the most disheartening part, HR/Recruiting will not respond to any requests for updates. I thought I had a great interview then heard nothing, so I followed up and they completely ignored the emails. And I didn't even hound them...just 2 emails to find out where they were in the process, but no response at all.
