I applied for an android developer role, but the interview wasn't about Android at all. I spoke with a backend dev who had me write code to create a data class and functions for fetching client data. No Android questions were asked.

The interview process started with one round of recruiter call, but the recruiter rescheduled the call 5 times. When we finally connected, he sounded unenthusiastic, sighing a lot, and even mentioned being in a 'friday mood' on a wednesday. He asked what I knew about the company, and when I gave a high-level description, he made fun of me for not being detailed enough and implied I hadn't researched properly, coming across as rude. I won't be moving forward with them. He also seemed really fixated on the leveling for the position, which is unusual since titles can differ between companies.

So after I applied, I got this online assessment. It had two questions, both of them were string parsing. The first one I got right, but the second one was really complex and I didn't even finish it, but I still got to the next stage. Then a recruiter emailed me to set up a technical interview. I think it was about 60 minutes, maybe 45, I can't recall. We used a shared code editor, and the interviewer explained the question. I had to code it live while talking through it on the phone. They said I could use pretty much any programming language. I also had to come up with my own input and test cases. Whatever time was left, I could use it to ask questions or chat with the interviewer.
