I applied online. The process took 2 weeks. I interviewed at JPMorganChase in Jan 2025
Interview
Straightforward process:
1. Code Screen consisting of 2x LeetCode style easier Medium questions. (From what I read these can very a bit in difficulty and quantity. 2x Medium is similar to first rounds for Google L3 that I’ve also taken and cleared so I’d aim for that standard generally.)
2. Marathon day consisting of Systems Design, Behavioral, and Coding portions. Systems Design was fun and focused mostly on efficient architectures given certain requirements. (How to add such and such functionality to an existing deployment rather than OOD.) Code portion interestingly involved Code Reviewing alongside Algorithm implementation.
From what I read it’s good to study Priority Queues, Kadane, and SOLID concepts although these didn’t come up too much.
Process went quickly - 2 weeks and they were in batch hiring mode. Interviewers were competent and professional throughout.

Question 1
How to add some functionality to an existing architecture and infrastructure deployment in the most efficient way.
Was given a leetcode problem within the first 4 mins of the interviewer. Wish I was making this up. Interviewers did not really introduce themselves besides names, straight to the code problem.The interview felt extremely cold. No soul, no passion, no discussion
Asked very scripted questions and everyone took a lot of notes. I really enjoyed the people I spoke with and they really made me think about the role and my past

I applied online. I interviewed at JPMorganChase (New York, NY) in Jun 2026
Interview
Asked a few questions about C++ via a word doc. The interviewer was very rude from the beginning of the interview. He seemed to be angry at me for even being in the interview and taking his time. This person should not be giving interviews. Maybe he wanted to yell at someone who couldn't yell back. Very unprofessional, I ended the interview early because I was so upset.
