In addition to the comments from people above, I wanted to pass on what several DGSs have mentioned to me this cycle: a year off is definitely not a year lost. In my case, I’ve had nearly 3. And I thought I would be “rusty” going back into academia, but many of the DGS I’ve spoken to have said that having some work experience is an asset, too, because you’re able to do the less interesting “job-like” parts of the PhD that you might not have the skills for in undergrad. That of course depends on your previous work experience and how you approach tasks, but having a full time job might help folks learn how to balance their workload and be more efficient. At least that’s what some profs I’ve spoken to at visits said. It certainly did help me, I think, but of course this depends entirely on your working style.
