IMHO at your hours and exp (commuter guy) you really don't need these services (unless your a complete goof). At this point in the game you should know how to make an aviation/professional pilot resume. There are plenty of examples on the web.
Resume:
1. List name/contact info in some prof format at the top (name/address/phone/email)
2. List licenses and ratings (leave the SIC type out unless you want to be laughed at)
3. List hours - total,PIC, SIC, SEL, Multi, Turbine/jet, Actual Instrument and Night (round to nearest 10 or 100: ex. 4876 total time = 4900)
4. List job history most current/present to last going back 10 years
5. List education, if no college list flight training or both but make it short
6. If it is not too crowded and you have room list some 2 or 3 hobbies/clubs. EX: AOPA, Billy Bobs Softball League or North American Man-Boy Love Club if that is your thing.
Most companies (majors) are now doing apps on the web so a cover letter is going the way of the 50 seater. But if you must there are plenty on the web. Pretty easy - 3 to 5 paragraphs about who you are, what you want, your qualifications and how you can be an addition/good employee for that company.
As for the interviews:
Most interviews are now TMAAT questions. These are all over the internet. The basic jist is they set you up with a situation and want to see how you handle it. The general way to answer these is to:
1. Address the situation WRT the question asked
2. Solve the problem/situation WRT question asked
3. End by telling how you and your co-workers (remember no I in TEAM) came out for the better, or the customer/pax went away farting roses or better yet how your actions helped line the CEO's pockets.
Sim ride - also going the way of the 50 seater but if you have to:
1. get the profile
2. practice on a desktop or chair fly
- really though, Your flying a SAAB and have an ATP. So it is reasonable to expect that you can: Run a checklist, T.O., Fly a radial, Enter a Hold, Answer some questions while flying instruments, Shoot an ILS or LOC and Land.
Any tech questions are likely to come from the ATP or COMM knowledge sector. Also from the AIM. Any a/c type question about systems will be general or if the company you are interviewing with flies what you are currently flying or have flown it may be more in debt.
So lets review:
1. Brush up your resume and logbooks (write a cover letter if you want an A++++)
*****1.5 Brown nose your friend at that airline to walk your stuff in - get a rec
2. Fill out apps. online
3. Get a Navy Blue Suit that fits (seriously if we are at this level and you already have a pilot job then your a lost cause)
4. Download all types of TMAAT questions. Practice them with your airline friends. Look through your logbook and pull situations from your flying past to use in the TMAAT questions
5. Review ATP and FAR/AIM gouge, know numbers and systems for your current turbine aircraft
6. Hand fly more often, get sim gouge (if applicable) and chair or desk top sim fly
7. Drop 10 pounds
it is all a crap shoot anyway. good luck. don't waste your $$
