I've been lurking here for years and I'd like to cover a topic that isn't covered that much.
Bioinformatics is a tough field to not have a PhD. Nonetheless, research positions do exist where only a bachelors is required and research experience is also stated as between 0-2 years. I'd like to give a hypothetical situation that describes a good percent of such applicants to these positions. The motivation here is to survey what are ultimately core requirements for these positions and what is maybe considered "bells and whistles".
I'm fresh out of college and I have a BS and/or Masters in Bioinformatics along with ~two years research in a lab. I'm applying to your lab, what are you looking for? And what requirement(s) can you excuse or not weight that heavily?
Edit. Sort of a related question, is requiring knowing hadoop and also the biochemistry/biophysics behind RNA-seq at the same time an outrageous expectation for a non-Phd?
We have had some undergrad/bachelors level bioinformaticians make some nice contributions and get published in our lab. They did not have much in the way of specific prerequisites, more just being smart and a willingness to hack.
By the way, if you're in Ohio or willing to move, we might want to talk to you :).
