First-hand accounts from people who interviewed at Red Hat.
Software Engineer
So I had like three rounds spread out over a few weeks. The first one was like a quick intro, then a DSA coding question, medium level I'd say. The interviewer was chill, gave me some hints when I was stuck, so it felt pretty conversational. After coding, we did some technical deep dives. The whole thing took about an hour and fifteen minutes. I felt okay, but definitely missed a few easy things. Got an update after like three weeks saying I'd move on. The second technical round was more about the actual job stuff, day-to-day tasks, which was pretty easy. The last round was with the hiring manager, and it was more of a chat about team culture and how we work, and my background, not really a tough interview.
- Can you explain the difference between concurrency and parallelism, and also the differences in multithreading between Java and Python?
- What is the difference between Docker exec, start, and run commands?
- Could you define serialization and deserialization and explain their working mechanisms?
Marketing Manager
The TA interaction felt transactional. Some questions focused on my job search outcomes, such as why I had not received offers after multiple interviews, which did not feel directly related to evaluating my fit for the role. There was also a strong push to schedule interviews within a very short timeframe. When I requested additional time to accommodate my schedule, I was informed that the process would move forward without me and that I might be re-invited if a suitable candidate was not found. This approach felt inflexible from a candidate experience perspective. During the interview, the interviewer appeared distracted, frequently typing on her screen and showing limited engagement, which made the conversation feel less focused. There were also discussions around topics that were not clearly aligned with the role’s responsibilities, including questions related to my layoff and whether my entire department was affected. After completing the first interview with the hiring manager, I did not receive any follow-up communication or updates. Overall, while Red Hat is well known in the industry, the interview experience did not feel as structured or candidate-focused as expected.

Solutions Architect
My interview journey started with a recruiter call that felt really good, professional, and friendly. Then I had a technical interview that included a presentation, which was a cool way to test skills. But the last interview, a behavioral one with two managers, was a bummer. It went way over time, like 45 minutes too long, and they seemed checked out and rude the whole time. I was told I'd hear back in two weeks, but I didn't. I nudged them a month later and just got an automated rejection email. I put in over five hours preparing and interviewing, and a quick update or a short feedback call would've been basic respect. It's important to treat applicants like people, not just data. This poor communication and lack of empathy really left a bad taste. Because of this, I'd never apply to Red Hat again and wouldn't suggest it to friends.

MLOps Engineer
The whole interview process was done without talking to anyone. It was all async. First, I had this big written test with some really personal questions. Then, there was a psychometric test. After that, I was told I didn't pass, so I guess the test was the issue, but I never got confirmation. It felt super impersonal, like it was all just automated stuff and not really looking at what I can do.
