Metron, Inc. Software Engineer Interview Questions
& Process

So first I had this online interview, it was like 1.5 hours. The first 30 minutes was with HR, then an hour with a technical software engineer. He asked me about my resume and experiences, then we moved to CoderPad where I solved a leetcode style question. After that, I got to the final round, which was a pretty long 5-hour in person thing. It started with a tour and some QA with the HR head. Then I had two 1-hour interviews with software engineers. They both asked me some questions and then had me do leet code questions on a whiteboard. After that, I interviewed with two directors for an hour. They also spent a good amount of time talking about my experiences and finished with a leet code problem. Finally, there was a "demo" meeting where a software engineer presented a problem and asked how I'd approach it before showing me their solution.

It started with a recruiter call. Then I had a 1 hour meeting that was half behavioral with a technical question at the end. The last round was 5 hours long. It had 3 rounds that were behavioral / technical, then they did a software demo of their product and finally a wrap up call with HR to answer any questions. The leetcode style questions were math heavy. Not hard to come up with any solution, but you'll need a good math background to solve them optimally. They called me saying I was rejected.

I had a technical phone screen where they hit me with a bunch of Java trivia. It was okay, only a few I didn't know immediately. I could figure out the answers using logic, but it seemed like they penalized me anyway for not having them memorized. The interviewer was super nitpicky and asked some nonsensical or trick questions, like 'this or that?' when neither was the right answer. It makes me wonder if they're that picky in interviews, what's it like working there? And they really didn't like that I used problem-solving to figure things out instead of just knowing the answer.
