Technical Coding Behavioral
The process included a HackerRank assessment followed by a "super day." The super day had two 30-minute interviews. One was entirely behavioral, where technical aspects only came up when I discussed my projects. The other interview was a bit more technical, covering concepts like the difference between lists and arrays, and what OOP is, with some questions going into more detail on topics I wasn't familiar with.

Coding Technical System Design Behavioral
The interview process involved a mix of coding challenges, focusing on medium-difficulty algorithmic problems like strings, graphs, and sliding windows. There were also questions about code review and debugging, where I had to identify and fix issues or inefficiencies in provided code. System design questions were asked, ranging from designing a new system to optimizing existing ones. Additionally, behavioral questions about past experiences and projects were included, with some rounds involving detailed discussions about my resume and projects.

Technical Behavioral
So I interviewed for a software engineer role and the first chat was fine, but the technical interview was the total opposite. It didn't follow the plan we discussed initially and the interviewers were really cold and rude. One of them even made a disgusted face when I was trying to answer, which is rough when you think they might be your future colleagues. I also think one of them was on their phone instead of listening. So yeah, I really didn't like the interview and it left a bad impression.

Quoted word for word from J.P. Morgan interview reports.
“Given a positive integer, write a function to determine if it is self-descriptive. A number is self-descriptive if the digit in each position corresponds to the count of that digit within the number, considering positions labeled from 0 to N-1.”

Read reports →“Write code to take an array of integers (potentially containing zeros and repeated numbers) and shift all non-zero elements to the beginning while preserving their relative order, followed by the zeros. Example: Input [0, 1, 0, 3, 12] should output [1, 3, 12, 0, 0].”
