I've been through it, and unlike CT's comments having a referral was not a factor - I had none.
Here's some tips:
- You will be nervous, but never let them know that
- Be on time. Construction is all about being punctual.
- Be polite (but not to the point where you have a brown nose).
- Be sincere. If asked if you have bent 4" RGS is a ditch, but you have only bent 3/4" EMT is an open warehouse say that.
- Dress accordingly. A suit and tie is NOT required. Some applicants will be wearing Sunday best, others have a job to goto after the interview. Somewhere in-between is best..."1 step over what is required for the job" is what I had someplace.
They will probably ask you:"Why do you want to be an electrcian?"
Have an answer ready for that one.
