Coding Technical System Design
First I chatted with the recruiter about the job and what they were looking for. Then, I had two coding screens to test my skills. After that, I went into a panel interview with five people, including the hiring manager, where we did more coding and talked about system and architectural design.

Coding Behavioral
A recruiter reached out after I applied. The recruiter was amazing, answering questions daily and speeding things up. It's a pretty standard engineering loop with online assessment, coding, and behavioral parts. I got through about half of it. The reasons for not moving forward were kind of disappointing, which was a bummer since I thought I did okay. It's weird how that happens.

Coding Technical
I applied online and a recruiter reached out. After that, I had a coding interview which had two rounds, each an hour long. The first round was a technical coding interview where they asked about my Kotlin experience and DSA with a use case problem, not like LeetCode. The second round was an Android development coding interview to test my knowledge in that area. This round was unexpected as I wasn't told it would be Android-specific, I thought it would be like the first round. I did well in both rounds, but then they went silent and I didn't hear back. The recruiter was nice, and the interviewers were pleasant. Not sure what happened, but it was a good experience overall.
