Wise interview questions

I was called for the first interview after completing an online test. The first interview was about an hour long. After a couple of days, I was notified I proceeded into the last round. The final interview took about 30 minutes.

Very unprofessional and mismanaged recruiting process. I was told that there will be 5 Rounds - 1st - 30 min video round - focus on motivation for TW, background, role fitment; 2nd - Management Task/ Case Study ; 3rd - Video Technical Round; 4th - Video Hiring Manager round; 5th - CTO/ Director round ( in-person/ Video ) It took 2 weeks to get the interview scheduled after the initial employee referral. The 1st video round was with a Product Manager in London, which ran for 1 hr (supposed to be 30 min) it felt that its a +ve sign as the interviewer is so interested in continuing for an 1 hr. I was asked to share my ideas for TW USA. So I created a comprehensive 10 pager document with my research, ideas and existing bugs in the application and sent them to HR and the Interviewer to share with the entire hiring team. TO my surprise the HR went into a complete silent mode and even after following up twice, no body responded back on the feedback or status of my profile. No body even acknowledged that they are receiving my emails or not. As if I was completely and purposely ignored. Add to the insult, after 3 weeks of silence i got a generic email stating they have selected other candidates for next steps and my chance ended there. Utter ridiculous experience - worst recruitment experience from a company that is one 1 of my desired products to work for.
