Upwork Project Manager interview questions

Horrible experience. They chased me down, yet the moment we started exchanging emails the hiring manager stopped replying. According to who contacted me first, they "are the best the Bay Area and did not like that I introduced myself listing my experience." Seriously?

One phone screen with hiring manager, one homework assignment, one on-site interview with 4 folks of all levels within product management, another on-site interview. After I submitted the homework assignment, apparently it was sufficient to be invite on-site. After the first round of interviews on-site, apparently I did well enough to be invited back for some time with executives. I felt I did decently well in almost all of the in-person conversations that I had. I followed up with the recruiter 3-4 times with no response. I finally called directly and they were surprised that I was calling. Soon I received an email from another recruiter saying that the position had been filled recently. Not sure if this means that they were keeping me as a backup candidate or they are just plain bad at following up. Although I see some great potential in working at this company, the recruiting process should be more responsive. Not replying to emails for 2 months is not excusable.
