Our team is primarily engaged in full-stack development. I usually work with the Vue framework on the front end, combined with Java and Spring Boot on the back end for web development. For new colleagues, the lack of systematic training makes it relatively challenging to get up to speed. Moreover, the company doesn't allow much time during office hours for learning, so they have to rely on self-study after work. However, based on my observations over the past few days, he hasn't shown much initiative in self-learning.
