Girth, don't know the details of the tech quiz but if I were you would read,learn and inwardly digest "Handling the big jets" by DP Davies. Also have a flick through your perf A stuff so you know what a balanced field is.
Amex, Go recruitment and training 01279 661347. Jill Milne is the lady in charge.If you haven't got a 737 rating and some experience on it then they will not be interested at the moment due large numbers of type rated folk around.
Easy are also recruiting, type rated preferred. Just for comparison they are looking for F/O's who can be quickly promoted so minimum of 3-4000 hrs with 1000+ on medium jet.(25+tonnes).Given these minimums it is unlikely that Go will settle for less at the present time.Give them a call and find out.
All the best of luck.
NB
