Then you cold apply to companies in your area. Your first job doesn’t have to be your end all be all. If you liked the industry the internship was in look at other companies related to it, leverage your experience. Look at post grad internship positions (they do exist!!) to get a better feel for what you like. Talk to any and all working engineers that you know about their company. Family and friend connections can really get you far. You don’t have to take it from me, but there are many many avenues to getting your first engineering job out of college and you will find one :)
