What are my chances of being hired with bnsf?

I am 18 years old and have a interveiw scheduled in the next week. I graduate high school a year early and have job experiance working in forestry on a chainsaw crew(very odd hours) bit I'm 100 percent ok with working odd hours or even 7 days a week. Also I am currently a bank owned home asset home inspector. I feel as if I have had a large amount of safety training. Also how many people usually show up to hiring events in small towns in nebraska. Currently 20 positions open.
