I applied from the internet, and then I got an email said I need to answer some questions as the first round filter, then I got a phone interview chance. I planned it for a few days. I showed my logical thinking and proper communication during the interview. And when I encounter new questions that I haven't prepared, I just try my best to answer, even though I did not give the perfect solution, I showed my thinking process to the HR at least. The most important thing is you need to tell the HR what you will bring to the company, and what is your plan. You need to make specific examples instead of general words. Finally I got the offer.
