NVIDIA Senior Software Engineer interview questions

I had four interviews total, including screening, coding, system design interviews, and a conversation with a staff engineer. The interviewing process was smooth and pretty much straightforward. Yet, after sharing a reference declaration form, I was ghosted. Later attempts to reach the HR manager gave me little to no clarity regarding the status of the application. Every answer claimed the application "is in progress." It seems they're stockpiling candidates unless they find the suitable one, and then they don't even care about canceling the unfit applications.

I had a mixed experience with the interviewers. Some were extremely warm and receptive, and engaged with me throughout the interview and offered continuous feedback, whereas others engaged very little and seemed to be working on other things during the interview. I received questions that were significantly longer than can be fully completed during the time allotted. I repeated the question after the interview for practice purposes and even knowing exactly what to do I was only able to finish about 30% of some of the exercises. I had to code nearly the entire time allotted. The role primarily mentioned Javascript and frontend development, and I was only asked frontend questions., not any of the more FAANG style algorithm questions tagged with NVIDIA on leetcode. I rated my overall experience negatively because all interviewers should be engaged, and if a question is significantly longer than what a candidate can expect to complete, it is a good practice to state this upfront.
