Round 1, chat with one of technology managers about the company, the team, the product, and my experience. Round 2, an Android coding homework. A weather app demo, not an algorithm problem. Round 3, chat with the Product and the QA about the product, and cooperation and coordination between teams. Some behavior questions. Round 4, review the Android coding homework with engineers. One of them was very impatient. The interview was very awkward. They wanted a senior-level engineer. But on the JD, they don't say what level they need. And I have emphasized I am not a senior engineer during the first round and the interviewer of the first round said they accept all levels. I wouldn't move forward if I knew the team wanted a senior engineer. I don't why they scheduled the rest several rounds for me.
