Tailoring Your Resume
Because you are likely to apply to hundreds and maybe thousands of jobs in a given recruiting cycle, it is implausible to tailor your resume for every role, even if that is ideal. Practically it makes more sense to create tailored resumes for particular types of roles. For example, you may create a resume each for product manager, software engineering, and machine learning engineering roles. Doing so is definitely not mandatory however and you can find great success with mass applying with a single resume.
