Builder.ai Back-end Software Engineer interview questions

1. Applied online 2. Recruiter reached out to me about the position 3. Talked with her about the company, sounded interesting 4. Had a video interview with an employee who was nice but suspiciously new to the company 5. Was invited to come onsite 6. When I got onsite, half the interviewers I was supposed to be talking to were not present. It was for somewhat understandable reasons, but still felt sketchy and my interview was cut short. 7. I was told the company would be scheduling another video round to make up for those who were not able to attend the actual day of the interview. I accepted even though this would've taken more of my time. 8. With no warning, two days after the on-site I was contacted with a generic rejection email, with zero feedback or transparency regarding anything that had transpired. This was in spite of the fact that a recruiter verbally told me there would be another round. During this whole process, the company came off as extremely unprofessional and I was shuffled between multiple recruiters. Would recommend others to avoid in the future.
