Gem Software Engineer interview questions

This was for the entry level fullstack engineer role. They reached out to me within a few days after I submitted my application online. First round was a 1-hour "data structures and algorithms" interview - not exactly leetcode, but overall straightforward and not difficult in any means. The onsite was in-person in SF (if you're local), consisting of a 1-hour values interview, 2.5-hour fullstack project, lunch with the team, 45-min product architecture discussion, and a wrap up discussion with the CTO. The values interview was a pretty standard behavioral. The fullstack project was definitely a curveball - they told me I didn't need to have any experience with the languages they were using (React, Python, Graphql), but it definitely required some affinity with those languages. I ended up "not implementing enough" of it, and they also told me that I should have talked to the interviewer more during process, while the interviewer told me the opposite during the interview - that I didn't need to explain my thinking or discuss much with him. The project was just to implement a calendar scheduling system, with provided skeleton code. The product architecture discussion was discussing the architecture of the project, and in hindsight you needed to have detailed pre-existing knowledge about HTTP requests or GraphQL requests, and be able to describe the exact interaction between the front and backend services. As a new grad, I did not know what exactly they wanted me to describe, as it was extremely open-ended and I had not done system design interviews before either. I was not given the proper resources to prepare. I would say the people there seemed nice and very smart, but my onsite was very non-standard compared to all the other interviews I've done, and I got screwed over by things I was not told to prepare for. Whole process was very speedy though, finished within 2 weeks.
