In the RD department of Fuqing TPV, the interview of the employer is relatively relaxed and easy-going, and there are also line tests and written English tests, which are relatively difficult. This department is mainly responsible for participating in the communication of business department requirements, making development plans, assisting in compiling functional specifications and implementing corresponding development processes. In our work, we need to modify, maintain and improve the existing application code. Generally speaking, compared with other departments, the work pressure of Fuqing TPV R&D department may be less.
