Well it's done so there is nothing you can do now so it is what it is.... I guess don't do anything illegal in the future so you don't have to worry about something like this.

It depends on the employer and how they run their checks. We do criminal checks for the purpose of renting to tenants and we go to county and we see all charges but we don't hold dismissed charges against people. I do tend to ask them what it was about though and it does make me more nervous to accept them. But that said, I have not really turned anyone down based on a dismissed charge.

Also some employers (especially small ones) who have exclusively white collar workers don't typically even do criminal checks. I personally have had 5 jobs and 2 internships. I have never had anyone run a criminal check on me. If I remember correctly, one internship had me do a drug test but can't remember circumstances too well.

I guess the most important thing is to keep up that 4.0 GPA assuming you are on a 4.0 grading system. I always thought the world of people with a 4.0. It told me that they will work hard and put in the time needed to complete their assignments.
