The process began with a recruiter screen followed by a CodeSignal assessment. Be prepared for a very fast-paced technical round: the problems are strictly time-bound (7 minutes for the first, 15 for the second, and 30 for the third). The final problem was effectively a "LeetCode Medium-Hard" difficulty level. Unfortunately, I didn't clear this round due to the optimal logical solution constraints.

Interview experience is overall very good. You can lead the discussion but they have certain questions to ask. Can choose any tools for diagram. Really nice people and very polite.

Interview
What a weird interview, or recruiter call.
Recruiter joined the call and got my name wrong, so knew immediately this was going to go sideways. They told me absolutely nothing about the company what they do, what they’re looking for.
Then got basic questions about my career. The recruiter couldn’t really grasp that one man teams really do exist at disorganized companies, so I think they had trouble understanding what full stack actually means outside of upstart. They kept rewording questions trying get me to explain what my teammates do, when in reality I explained that I don’t have any.
Then was told of the next interview steps. A take home coding challenge, then a virtual onsite with atleast 3 more interviews and a live coding challenge. Then interviews (more than one) with team members. How many interviews are we doing here? Then they will ask for references, and doubled down on how they take those seriously. Lol, okay?
I was honestly out on Upstart after hearing the interview steps. Wasn’t surprised to get rejected 24hrs later.
