L3Harris Interview Questions
& Process

The interview process kicked off in early January 2026 with an engineer reaching out to set up an initial chat. We talked about my background, what I'm working on, and my tech interests. After that, a recruiter got in touch, and within a couple of weeks, I was invited for an in-person interview at their Palm Bay, Florida office. They covered my flights and hotel, which was nice. The onsite part involved a panel with two engineers, a senior technical person, and then a separate chat with a manager. The technical section was solid, and the discussions were good. The manager chat was more laid-back but still useful. They mentioned they were seeing other candidates and I'd hear back in about two weeks. But then, communication got spotty. After the two weeks, I nudged the recruiter and was told it would take another two weeks for a decision. This happened a couple more times, and it took almost two months from the onsite to get a final word. While hiring can be slow, the long waits and lack of updates were a bit of a letdown, especially for a big company. Also, even though they paid for travel, I didn't get reimbursed for the day off work I had to take. So, the interview itself was fine, but the waiting game and communication afterward weren't what I'd expect from a company this size.

So, I had this interview with the Director and a team member, and it was a really good experience. We talked about some basic OOP stuff, a bit about DevOps, and I had to write a database query. They also threw in some behavioral questions, like how I deal with disagreements on a team and how I'd pitch my interests so the team would be excited to have me. I felt it went super well, they even complimented an answer I gave! I was really feeling the role because the team seemed awesome, the culture was cool (no work on Fridays!), and it would've been great for balancing my studies. I sent a thank-you note, and they replied super fast the next morning, saying they still had more interviews to do. Even though I was super into this opportunity and thought it was a great fit, they ended up going with someone else. Still, it was a really professional and respectful process, and I'm glad I got the chance to interview.

The interview process for this role was quite unusual. It was a brief 15-minute meeting with the hiring manager. I wasn't aware of the time limit beforehand, and neither was the hiring manager, who seemed surprised the recruiter hadn't informed candidates. The hiring manager spoke and asked me two questions, then I got to ask two questions, and that concluded the interview. It felt more like a formality to check a box for HR rather than a genuine interview. I felt it was disrespectful to candidates who put effort into preparing. I'm not sure if this is standard for L3Harris, but I was very disappointed.

So the interview process has 4 stages. First, you apply. Then there's a phone interview with HR. After that, an online interview with the general manager, which is usually behavioural and asks about projects you've done for work. Finally, there's an in-person interview with a senior engineer and the branch manager, which is about 2 hours long and includes behavioural questions, technical questions, and they show you simulations and FEA contour plots.
