Jet interview questions

Interviewing with Jet.com is total waste of time and should be avoided. Their recruiter reach me. After an outsourced interview via karat.io, I had an on-site. Interview itself was easy and last about 5 hours. On-site recruiter told me they will get back to me next day. I have sent and email day after the interview to thank you for the opportunity and their time. Few days passed but I haven't heard from them. I have sent another email to ask what they have decided. It's absolute silence since the interview. Only times that I spoke with their recruiter was when he first contacted me and on-site after the interview. Jet's being silent, not disclosing their decision ( even if it's negative ) or not even sending a "Thank you for your time today" email (as most companies does) is very unprofessional. Think about it, do you really want to work for a company that doesn't value people ?
