Well, it's a tough spot. From what I have observed, most forensic employers will grab an applicant with some degree of work experience, which leaves those without that experience still looking for a job. Ditto what Brenda said -- the fact that shows like CSI have made forensic science careers extremely popular means that competeition for even entry-level jobs is very, very stiff.
You haven't provided more details about what type of jobs you are applying for (crime scene tech vs lab job), so here are a few random recommendations:
1) Did you get around 30 hours of chemistry in with your BS degree? If not, you will be at an extreme disadvantage for a laboratory job. You may still do okay if you are looking to do crime scene work. With so many applicants with forensic degrees now (including master's degrees), you really need to know what job you are applying for and how your knowledge and skills are going to fit that job. If you need to take more classes to improve your skills or knowledge, do it. The BS is only the start of a continual learning process, and in and of itself will not get you the job -- it may have been different several years ago, but not now. Right now, employers really get to pick and choose from a pretty large pool of qualified applicants.
2) Something else to consider -- do you have some good references? You don't need ho-hum recommendations at this point.
3) It's not always about answering the questions correctly, but also about being honest when you don't know something or if you don't quite remember. Stay within the boundaries of what you know. (I have seen interviewees totally make stuff up -- it's very embarassing!)
4) Again, ditto Brenda -- If you have the opportunity and the means, attend a regional organization's meeting or conference -- see the links on the AFTE website for more info on various associations. National organization meetings (like AAFS) can be much more expensive, but go if you can (I think AAFS takes volunteers).
Hope that helps, and good luck to you! :smiley:
