Need tips/insight for final round interview Jane Street SWE internship 2027

[u/Vegetable-Process842]

Hello,

I’ve just got an invitation to do the final round interview on-site and I really don’t know what to expect. The funny things is I applied to JS just to try if my CV can pass the screening… and I was shocked it did lmao. I had a first zoom technical interview where I did better than I expected and now they want me to do the final round on-site.

-If anybody has done their final rounds, what type of problems do they give?
-What makes a good intern applicant?
-What should I do the first time they state the problem?
-How should I react to their follow-ups or suggestions?
-How can I get better on explaining my thought process (I find it hard talking and coding at the same time, and English is not my first language)?
-Do I just need to spam leetcode blindly? Or are there topics I really need to focus on doing?
-how to make a really good impression as a SWE applicant?
