background
I am looking for a job recently, and the epidemic situation is relatively serious, so it is very inconvenient. In the morning, I received a call from a headhunter, saying that a foreign company was recruiting for Flutter development. I did have experience in Flutter projects, and asked me if I was interested. After adding WeChat and sending information, I took a look. It is a very large medical company. For a foreign company, Deng X Bo has a R&D center in Suzhou, and the working location is very convenient. I made an appointment for a remote interview the next day.
