There are many things wrong with easyJet at the moment, but I would venture to suggest that the command process is not one of them.
Substantial numbers of my colleagues have been given their (well deserved) commands recently, and those I spoke to said that the assessment process and command course was fair and very thorough.
The only aspect of gaining promotion that I personally disagree with is the requirement to be sent to a non-preferred base for an indeterminate period of time, usually to accommodate direct-entry Captains.
For what it's worth I'd mention that I've found the training at easyJet to be second to none.
ps I don't see any bias whatsoever against Dutch F/O's - my F/O's have all been Dutch this week!
