Huawei Technologies Research Engineer interview questions

Applied online. After a few days, the hiring manager called me to talk about the team, the position and the next steps. A week after a senior researcher called me and we talk about my resume, my experiences, a little bit of technical things. Was very casual but interesting at the same time. He told me that there are many candidates but they have good feeling about my profile. After this initial (I guess screening) step, I had 2 online technical interviews with some researchers. They asked open ended questions like "how would you solve this optimization problem" etc. Was interesting and they were polite. Finally, call from the hiring manager that everything is going well and I should receive any day now a call from HR to start negotiations. Also, a final interview with the hiring manager's boss that overlooks the entire research division. Nice chat. I declined the offer as I had other offers at the same time and the compensation package, although good, was not as impressive as I would have thought/expected.

Two engineers interviewed about the technical contents for the job. Although I answered all the questions properly as I am knowledgeable in my field, but I didn't get any reply from the HR. It seemed that the interview was orchestrated to get know-how of my field rather than a genuine interview to hire me.
