You felt that you were being discriminated against because of your religion? Simply because you were not selected at interview, so you were that good, you believe the job should have been yours hey? What explanation do the majority of us get for all the rejection letters that dont turn up without an explanation as to why we failed selection, how do we justify not getting the job after obviously being so good at what we do?? It is nothing to do with religion, but what you are implying is that some UK airlines are being racially prejudice, an outrageous statement. This is the United Kingdom remember, pilots are employed from all over the world here, taking jobs from home grown talent, is that some form of discrimination against Brits??? To suggest that you are the victim of discrimination is ridiculous, spreading this tosh about is only likely to stir up tempers. Also implying that others like you are likely to be victims of such fantasy whilst job hunting is simply nonsensical and dangerous.
Believe me, this not a poke at anyones faith or beliefs, but enough is enough.
