I was just wondering if anybody could advice on any specific training or development within the aviation industry to be in a better position to gain entry.

I've been in the food manufacturing industry for a number of years and have good base knowledge in H&S (nebosh dip - grad iosh). I was invited for an interview with an airline caterer and although I managed the final stage, I did not land a job. I have been reading a bit on H&S in the aviation industry land operations, in preparation for my interview, and it is something that has really caught my attention and I would really enjoy doing. Is there anybody already in the aviation industry who could share some ideas and provide me with some advice?

thanks in advance
