Is it common to be unemployed or underemployed after getting a bachelor degree in accounting?

Also - take some online classes this summer. Beef up your skill set in financial modeling (excel), data analytics, SQL, etc. These are great skills to have and will absolutely be part of any corporate accounting / finance role. COurses are very inexpensive and thorough. Take a look at Cousera and Udemy. S just did a modeling course for $12 (seriously, and it was really good - about 20 hours of real learning using videos, lectures, assignments - which were impressive).

Employers will also like to see that you took the initiative to self learn and update your skills. Very important.
