Are both of you brand new to EMS? That could explain the silence; just keep throwing applications out there, as well as expand your professional resume (ex: college courses, becoming nationally certified, apply for ride alongs, paramedic assistance programs, etc)
Also: I assume you're both submitting your own resumes in addition to the company resumes?
Atlantic/Cataldo are typically hiring anybody with a pulse; HOWEVER their staffing is pretty good at the moment for BLS. They do entrance exams, but are so laxed they're more a waste of time (or in their minds a 'display of dedication') than a challenge. As BLS, you will see a lot of IFT w/ an alright amount of 911 (through Salem, Lynn, sometimes Saugus, etc).
Trinity was hurt pretty badly by the MA deadwood scandals; I know they're hurting for medics still, but not so sure about BLS. If you do get an interview, expect a decent entrance exam and a couple skill stations. Mostly you'll see IFT w/ a tiered response system in some communities (beware the volume psychs of Haverhill, lol). They pay quite well at the moment due to staffing being so poor; but be cautious about job stability because the owners WILL be seeing indictments...
Action recently hired a handful of BLS; I don't see them needing anybody presently but send them an app anyways. They just fired their clinical coordinator, so presently in their vacuum there isn't any kind of placement exams or organized interview process. Action, like Cataldo, is known for hiring brand new BLS. Expect mostly IFT with them, with a few emergencies to assist medics in Woburn, Stoneham, Winthrop, etc.
Armstrong IS hiring BLS presently, and like Action/Cataldo, they DO hire brand new EMTS. The company is similar to Action in regards to communities they serve. Last I heard they have no placement exams.
Little caveat with Lifeline; they typically want some experience whether you're ALS/BLS, and their paygrade isn't beyond any local competitors. They also do NOT give raises; ever in their 5 year existence. The owner treats his personnel as a commodity..
