Just wondering: the company where I currently work (and from which I have all full-time experience) is not very well known outside the industry. Within the healthcare informatics field, it's very well known and respected but! outside the field, I don't think most have heard of it.
Will this impact my application negatively? Anything I can do to prevent that?
Thanks for your help,
I don't think this is an issue - it'll be all about your essays and your work experiences. I met tons of people (including myself) at admit weekends who worked for small companies or large companies I had never heard of (along with plenty of the usual suspects as well).
If you are really concerned about it, have one of your recommenders write a 2-3 sentence writeup on your company in one of your recs putting your work experiences into the appropriate context.
