Applying for a job with a requirement of Java with Spring Boot. They told me they'd schedule an interview if I could learn Spring Boot in ~10 days. Is that a feasible time frame or nah? Also any resources to learn from are welcome.
Edit: I have zero knowledge of Spring framework or Spring Boot.
somebody did a minimum install of the framework (e.g. spring boot), then added things they might use for every project. This is usually login, register, reset password via email, or "login with github", other kinds of addons might include a specific javascript framework, CSS framework.
Often these addons will be opinionated. People publish these for fun or because they think they have a good practice/stack and want to lower the barrier for others to use similar tools as them, beginners benefit from having examples or from being able to save week(s) of time figuring out how to glue new tools together. Generally they help people start writing actual code for business logic ASAP.
