Applied through a referral

• Phone screen with a recruiter where they asked some basic questions about past experience, and then asked which roles I'd be interested in out of a few they had available
• Byteboard coding assessment where I was asked to leave comments on a design document + solve a coding challenge. I didn't finish the design doc but still moved on to the next round
• Behavioral interview with hiring manager for the team + a small verbal SDI where I proposed how to build a small search app
• Final onsite: Fullstack coding interview + behavioral interview where I talked about a time I demonstrated each of their four core principles + frontend SDI. I definitely ran out of steam during the behavioral and didn't expect the exact way they asked the questions, but I was most confused by the frontend SDI. The recruiter was really nice about providing an exact outline of the onsite and what to expect from the frontend SDI, and I then realized the frontend SDI sounded exactly like one of the free practice problems on the study resource they sent me. I couldn't believe their final onsite would pull directly from the site they sent me but I studied the problem solution as much as I could anyway, and on the day of the onsite they really did ask me to architect the exact practice problem. I wasn't really sure how to ask the recruiter about this so maybe that's on me.

After the onsite, the recruiter told me they felt pretty positive about my chances, even though they had found a better candidate for the position they were trying to fill. Then they ghosted me after insisting multiple times that my chances were good. I asked for followup and any critical feedback a few times and no response. I started the process feeling pretty positive about how helpful the recruiter was but felt weird about the onsite and didn't appreciate being led on about my chances at the position.

They ask you to provide an example where you demonstrate each of their four core principles.
