They split you up into 4,one does a multi choice exam,one does a verbal exam,one has the interveiew,and one does the practical,then they swap you around,questions were pretty straight forward think i got 2 wrong,one was the let by test for 35mm pipework,its 2.5mb if u get the same question i put 4mb durr,and one about which regulation aplies to something,i chose a bs number but think it was supposed to be part j,and 8mb drop for the e6 meter if that questions there,the fault finding was on an old open flu boiler,piece of cake,was the cylinder stat fault but that could change for your assesment,and just have to tell them everything thats against the regs on the instalation.
The interview was a bit starnge asked loads of questions that were a load of crap,like what do you do to make yourself a better engineer,hos do you cope with a customer going ape ****,i told him have never had a customer mouth off at me,he asked why,i said its prob because im 6`4 and 16 stone to which he pulled a face lol.
I did not get offered a job but had allready decided not to take the position anyway so it didnt bother me.I think if u want to work for a big company then BG is far more atractive,after reading the advice given to me on here about eon,the shifts did sound a bit crap to me, although the basic of 34k includes all your standby payments,its still a very good basic wage.
Best ofluck with the interview
