Wolfman21 - I noticed no one has answered you yet, so thought I would try to provide some related info that may, or may not, be helpful. I know it's a very frustrating process to have completed the application process, see those openings listed on company sites and still hear nothing, but it seems lately this experience of getting no response from the contract companies is fairly common.
It's my understanding that with the last round of contract bids, most of the contract companies cut staffing. While I heard one company cut over 30 ATC staff, I believe Serco cut far fewer — but that still leaves several former Serco employees who might be in line for first right of refusal for any openings Serco has. There was an Executive Order issued recently about "Non-displacement of Workers" that suggests the contract companies are supposed to hire from the ranks of those they cut, before opening it to new hirees, but I am not sure how all the details actually play out. For instance, I don't know whether or not this applies only to the specific facility where the cuts were made or if someone cut at one facility has right of first refusal for openings at any of the company's facilities. Also, since this legislation is new I don't know how/if it will actually affect hiring since there seem to be ways to get around it.
Serco does show openings and I've heard there are/were openings in Mid West and RVA, but I also hear things are sort of uncertain right now. The FAA was expected to be taking in a lot of new recruits to fill their staffing shortages and certainly some from the FCT system hoped to go with the FAA, but I also heard the FAA may be taking on part-time retirees to fill some of those shortages, so it's hard to know what and where the needs for ATC staffing will be in the short term. In addition, this last round of bids seemed to be particularly chaotic and confusing for ATCs and contract companies and the "fall out" of changes in contract terms, in re staffing levels, benefits, etc., caused some angst in some places — and the entire contract bid process and announcement was delayed several times so the companies may still be trying to "catch up".
In the contract world of 5 years ago, it seemed the best method for getting hired used to be 1.) apply with the contract company. 2.) send resumes to the facilities you are interested in. 3.) call and/or visit the facilities you are interested in. 4.) Call again in a few months to see if anything has changed. 5.) If you know people who know people at the towers or in the contract companies, get them to put in a good word for you. Different companies handle hiring decisions differently. Some leave much of the decision making to the facility managers while others do all the decisions from their management offices with little or no input from the facilities. And, as mentioned above, I'm not sure how much effect the new "non-displacement of workers" legislation will have on hiring decisions at the facility level now.
Sorry I can't be more directly helpful, but I would say keep politely persevering and good luck!
