It shouldn’t take you months and months to get the basic hang of your job. It takes around a year to fully figure out your role in the company, and it’s okay if you’re not literally an expert on all of the happenings of the company six months into your position. Heck, it might even take a few years to feel like you’ve completely gotten a grasp on what you’re doing in your job. That’s why it’s not great to job-hop every year. If you can grow into your role instead of speedrunning it and leaving at the first sign of strife, you’re going to learn a lot more about yourself as a professional. Unless you’re really good at every job you get right off the bat, you shouldn’t leave a job you don’t even have a full grasp of to begin with.
