Do I need to go to grad school to find a decent job?
This answer will depend on what industry you're interested in. Speaking from a finance/accounting perspective, I find that there is no difference between those who attended grad school and those who did not. Even with our starting salary is the same for those who attended and those who didn't. For accounting, a masters degree may give you a wider education, however once employed, I find that my job is so specialized, I rarely use the wide breadth of knowledge I learned.
To differentiate yourself, grad school is not necessarily the only way you can do that. There are other reasons on why grad school may be necessary though. It's important to consider if it is the "norm" in the industry, or if a grad degree is required for a certain certifications.
Good luck in your journey!
Unfortunately the best answer to this question is that it depends on what field you are specializing in. No, it is not required to complete grad school to get a good job and make a name for yourself. All of that is up to you. Employability typically starts with a bachelor's degree, track record of success in college and your aptitude to perform a role. If you are in a field that requires a Master's to advance, then yes grad school is needed. But, if you are in a general field that allows you to start work following a bachelor's, then it is completely up to you to succeed.
I, myself, just have a BS in Finance. I started in an entry-level role that did not pay much, but I worked hard, paid my dues and rose through the ranks to where I am now. Some folks would argue you need an MBA to achieve a certain amount of success in the business world, and I would still encourage folks to do that, but it was not needed to reach the level I am out now.
