With regard to the numbers being let go, I recently spent some time at TK. Several reliable sources said that as many as 30+/- had been let go over the past year. Reason, primarily attitude and the inability to put their smartphone away.
Apparently one 'dude' even told the examiner to standby while he answered an incoming text on his smartphone. That ended the checkride right there! Given that the briefing guide addresses smartphone usage, answering or responding to a text is considered as 'intentional non-compliance with SOP' and is grounds for failing a checkride.
Another individual got a little sassy when a certain (lady) chief pilot visiting TK, made a comment about his facial hair and overall slovenly appearance.
Assume that everybody you meet at TK outranks you - they do!
Just because you were lucky enough to get hired, you still need to make it through probation! You are being watched and should consider your probationary year as one long interview!
