Discovery, Inc. Finance Manager interview questions

One of the most classless interviewing experiences I have ever had. Initial HR screening, followed by a VC interview with the hiring manager, followed by two separate in person office visits. After a week and a half, followed up with an email and heard nothing back...not even a considerate "still in the process" message. Followed up twice more with no answer only to eventually receive a generic rejection note from HR 3 weeks after. After several interviews, they should at least have the decency to call you. They went from being high on me to complete silence and basically wasted my time.
