BoxBoat Technologies Devops Engineer interview questions

I was contacted out of the blue from their internal recruiter. She wanted to know if I would be interested in working for their company because my skills matched up with what they were looking for. I looked into the company a bit and it looked like a very cool place to work with a lot of smart people. I did an initial phone screening with the recruiter, and she said she thought I would be a great fit and my salary expectations were in line with their budget for the position. Next, I had a 1 hour phone interview with a solutions engineer. I was told that I did well and they thought I would be a great addition! The recruiter set me up for another 1 hour interview with another solutions engineer. That interview also went well. The interviewer said he was going to give positive feedback about me. All of the people I talked to were great. In fact, everything went great up until this point. Then the company went completely 'radio silent' on me. I emailed expressing my excitement and asking about the next steps and didn't get a response. Then I emailed again, weeks later, asking if I was still up for consideration for a position. Three weeks had passed, and I got absolutely no responses. This was a negative experience for me because I was expecting to at least hear something back.
