Technical Coding Behavioral Presentation
The whole thing took about a month and a half, with 3 rounds. It started with a recruiter chat, then I got a coding test in Java, Springboot, and Maven. After I passed that, Round 1 was a chat about my resume and a coding challenge with follow-ups. They asked some tough questions, but I nailed them. Then they asked me to come to Columbus for an onsite. Round 2 was a 1.5-hour panel interview with 4 people. They started by asking about my resume and overall experience. Then came technical questions on SQL, Sessions/cookies, and Java Regex. We also talked about their current projects and how I'd handle certain scenarios and expected technical challenges. Round 3 was a call with a product owner and a principal software engineer, which felt more like an HR thing. I think they didn't like my answer about the toughest challenge, as I went too technical. The PSE mostly grilled me on Kafka follow-ups, which felt off-topic. The PO left early, but the PSE and I kept talking about the company and my interests for a while. I waited over a month for an update, and they kept saying I was still being considered, even though I followed up weekly. Finally, they rejected me, saying I had good technical skills but lacked product experience, which I still don't get why it took so long to tell me.

Behavioral Technical Coding
It was a three-part interview process. First, an initial chat with HR to go over everything and answer my questions. Then, a Java and OOP interview that was pretty broad, not super deep, easy if you know Java and OOP from a CS course. Finally, another technical part, but this one was really focused on specific Java features.
