Upstart Sr. Software Engineer interview questions

This is the most unprofessional experience I have ever had. Technical screen. Recruiter phone call. Behavior screen with manager. Full onsite. Design + project + code + manager. References. Throughput the process, I was interviewing for senior software engineer. After full onsite, recruiter told me verbally that I will be getting an L5 senior software engineering role. They put me through reference check, and 2+ weeks of radio silence, I get an L4 offer. This was a terrible waste of time of my references. Very unprofessional behavior. Like car salesperson bait & switch. Please be very aware.

I applied online. A recruiter reached out to me and scheduled a call. The call was a weird experience for me as the recruiter was asking me for my references from my current company manager, which I declined. I mentioned I can get a reference from my ex-team lead, but she wanted my manager's reference. I thought she wouldn't move me forward, but after a week, all of a sudden received an OA to complete, and they wanted it done in 2 days lol. After that, I was asked to schedule a hiring manager round. The manager asked me questions related to my project in detail and a few other questions. I felt the interview went quite well, but the next day an automated response came that they're not moving forward. I was looking at other Glassdoor reviews of this company and didn't find a single review where someone actually accepted the offer, so I got an idea from that the kind of company this is.
