Rentwell interview questions

Went through 3 rounds virtually, thought it was going super smoothly. My fourth interview was in person. I drove 3 hours from my hometown for a 15 minute powerpoint presentation from the would-be boss. It was fine, whatever. Still wanted to work there. They said they'd get back to me in 3-4 days about the decision. 3-4 days roll around and I hear nothing, so I politely emailed my recruiter & called the main office. No response. It has now been almost 2 months since I interviewed there and they NEVER got back to me. After 4 rounds of interviews and a special trip across state lines just to meet the company, they ghosted me. Absolutely ridiculous. This was definitely the most unprofessional experience I have ever had interviewing in my life. Not to mention-- super degrading as a job seeker. Luckily I landed with a place that actually cares about their employees and job applicants.
