From my experience, this is the first of two technical coding interviews they do during the superday. For me there were five other rounds before I was invited onsite, including two take home assessments.

This feels like the question they expect you to finish in the given time, the "easy" question. The question I was ask was a bit harder, but in hindsight my unfamiliarity with the question made it feel harder than it was. The minimum expectation is a mostly complete and actually working implementation. I can't confirm this but my understanding is missing major edge cases means failing the interview. I am surprised the interviee started typing as quickly as she did, I believe I was asked to write more detailed pseudo code first.

There is a second more advanced technical interview asked after lunch. I didn't interview online, I interviewed in person so I am sure that changes some things.

I did not pass every stage of the onsite, but it was one of my better interviews experiences. No one applying to Jane Street does so without knowing how rigorous the process is, I don't hold it against them. It felt like everyone I met wanted me to pass the interview. I can't say that about every interview I have been on.
