I recently got a call for an interview at Omni. I did LOTS of homework and thought that I might help ease the research load for anyone interested.
(Please don't flame me on this, this is my research only. I spoke to several people inside the company and several ex-employees. I do not work for them and I did not attend the interview based on my goals, so I cannot give you much of an interview gouge.)
Interview: What little I know is this, background check, basic technical knowledge test (instrument procedures,) PC-based simulator check (to verify that you can adapt and know the basic procedures) non-technical interview, lunch...potential offer. That is all I know.
Schedule: The proposed schedule is 18 on, 12 off with a 4 day non-voluntary hold out. However, they often ask you to stay on longer (than 22 days) if you're needed. They may or may not give you a choice. I was told that upgrades are based on 'dedication' and your unwillingness to stay gone after 22 days may affect your upgrade time. However, this comes from an ex-employee, so that is unverified.
Pay: The pay scales on this site are correct, about $36,400/year to start. You are paid additional money on any day over 18 and regardless of your flight time, you are paid on day 19 as if you had started into hour 61 (since the guarantee is 60 and you typically won't fly that) and given an additional day rate. I was told $250/pay for an SIC but could be wrong. Second year pay is a tiny jump, but the potential to make captain is based on proficiency and recommendation, so it is possible (and I was told likely) that a smart pilot with good skills and a fast learner could upgrade in 24-36 months.
Union: They have been in union negotiations for 3 years with limited progress. I wouldn't expect that they get a contract very soon, but others are more hopeful.
Potential: By my evaluation, this is a good opportunity for a single person to gain lots of heavy jet international experience fast and make a very fast upgrade. Generally a good company (although I think the pay is WAY low) but you are going to spend TONS of time away from home. (So, it was not an option for me because I have a young family.)
Again, this is my research and I am trying to present just facts here. Where I have interjected opinion, I have tried to be clear that it is opinion. I think Omni has great potential for the right person.
Hope this helps!
