***Note to self, never scan the forums for a laugh just before going to bed as this can happen.***
I have a lot of experience working for Showsec over the years both casually and from a position of some authority and can say, honestly, that despite the companies bravado it is very poorly managed and chances of actually progressing are pretty slim.
Actually having been an interviewer for them is a bad joke, the current process is fine in itself depending on the interviewer, you will be asked 7 questions that are designed specifically to coax answers out of the brain dead masses that mostly apply.... However it's pretty much a certainty that you have the job! The interviewers are told they have say over whether you are hired or not, they're usually guys and girls you'll actually be working with at venues; and that decision is made before you've had chance to stand up and walk away. But the Recruitment department can and most likely will over rule the interviewers decision, if it's a fail, so that they can meet their quota's.
Actually getting work out of them is difficult at best unless you're a really great *** kisser.... In theory once you've done your induction you're given your log in details to access the staff portal. You can fill in your calendar with what days and times you are available to work and periods where you cannot for whatever reason. From this the bookers are supposed to identify how many staff are needed for a particular event and share out work fairly between those on the books.
What happens is rampant favoritism, If you kiss your area bookers *** like John Cena does to Vince Mcmahon, never turn down a shift ever you'll get preferential treatment. Turn down a shift for whatever reason or the booker decides they don't like you and goodbye work! You'll get very little, a lot of what you get put on for will be taken off you because they've had to reduce numbers.... if you're SIA you'll be offered those few meager shifts as a lesser paid steward etc etc.
Never think that you can rely on Showsec for regular income, take what you earn from them as a bitter sweet blessing each month that might pay your internet bill or something and resign yourself to looking elsewhere for a more stable income.
Good luck though mate...
