Ennie,
A friend of mine has just passed an interview and sim with TCX.
I believe it was a very light interview, with a few Perf A type questions.
The sim was on a 757 at BA Heathrow. 3 departures apparently and a self critique after each one. No failures or swerveballs.
Very straightforward apparently. Just as the company is generally.
Expect to join a long seniority list with probably 160 FO's ahead of you for command..... about 12 years currently.
