"I have heard that your facility is a very safe, organized, and positive place to be. After meeting with you, I can definitely see these things to be true. I would be more than happy to be able to work here."
2.
How important is safety to you?
Discuss with the hiring manager what safety means to you. Emphasize the importance of safety in the workplace.

Rachelle's Answer
"To me, safety is the basis of everything that we do. If you are not safe on the job, you could lose everything. I am sure to practice best safety regulations at all times."
3.
How do you determine the pipe thickness needed in a line?
Walk the interviewer through your process of determining pipe thickness needed in a line.

Rachelle's Answer

4.
How much experience do you have reading piping isometric diagrams?
How much experience do you have when it comes to reading piping isometric diagrams? Talk to the hiring manager about your level of comfortability in this task and how often you come across this task in your current role.

Rachelle's Answer
"Currently, I am responsible for reading piping isometric diagrams on a daily basis. In total, I have approximately 4 years' of extensive experience in doing so. I am very comfortable with this task."
5.
What is a butterfly valve, and what situations would you use one?
When you answer this question, keep it simple and to the point. Display to the hiring manager that you are able to easily and simply relay basic concepts of pipe fitting.

Rachelle's Answer
"A butterfly valve is a valve consisting of a pair of semicircular plates that are attached to a spindle across a pipe and hinged. They are used to allow flow to go only one way."
6.
What was the most challenging piping installation job you have done?
Talk to the hiring manager about what you feel is the biggest challenge in this line of work. Be careful to not sound negative or complain about your current position.

Rachelle's Answer
"I feel that pipefitting is one of the most demanding physical trades. You could be working on equipment underneath piping, structural supports or vessels; and the next day you could be up and down on a 30 foot ladder. It's highly demanding work and not for the faint of heart."
7.
Why do you believe you are the best pipefitter for us?
What makes you a stand-out candidate? Talk to the hiring manager about why they should hire you for the job.

Rachelle's Answer
"I believe that I am the best pipefitter for you because I bring a great amount of experience in the exact type of work that your facility focus' on. I am well educated with a strong safety record and come with excellent references."
8.
What do you dislike about being a pipefitter?
If you had the ability to change anything about your career as a pipefitter, what would you change? It's best to not turn the conversation into a negative tone, or to complain about your current employer. Choose to answer in a way that your 'dislike' is not something that is crippling to your success in this position.

Rachelle's Answer
"If I could change anything about being a pipefitter, I would ask that vocational schools focus on it a bit more when it comes to the options that they offer. More people are aware that they can be a plumber, or a welder, for example. Pipefitting seems to take a back seat in the sense of trade school options."
9.
What is a globe valve used for?
When you answer this question, keep it simple and to the point. Display to the hiring manager that you are able to easily and simply relay basic concepts of pipe fitting.

Rachelle's Answer
"A globe valve is used for regulating flow in a pipeline, consisting of a movable disk-type element and a stationary ring seat in a generally spherical body."
10.
How can you tell if a gate valve is open or closed?
When you answer this question, keep it simple and to the point. Display to the hiring manager that you are able to easily and simply relay basic concepts of pipe fitting.

Rachelle's Answer
"You can look at a gate valve and tell if it is open or closed by the position of the stem."
11.
If you don't know the answer to a problem, what do you usually do?
Do you ask your employer or co-workers when you have a problem or need an answer? Are you the type to find the answer before you ask anyone for help? Talk to the hiring manager about how you go about finding the answer to a problem.

Rachelle's Answer
"If I do not know the answer to a problem, I will usually first search for the answer. I do not want to bother anyone while they are busy so I will first try to independently find the answer."
12.
When did you become interested in pipe fitting?
When did you first realize that you wanted to be a pipefitter? Talk to the hiring manager about where your interest in this line of work arose.

Rachelle's Answer
"I decided that I wanted to be a pipefitter when I was in vocational school to become a plumber. The classes were so interesting to me and once I realized it was an option, I fully focused on pipe fitting."
13.
During vocational school, what was your best subject? Which subject did you struggle with the most?
Tell the hiring manager about your best subject while attending vocational school. Why do you feel it was your best subject? Discuss the same in regards to your most difficult subject.

Rachelle's Answer
"While attending vocational school, my best subject was on commercial plumbing. I feel that it was my best subject simply because of my interest in it. I also felt that I could relate best to that particular professor. I had the most difficulty in the math related courses, as math isn't naturally my strong suit. I have taken additional training in that area."
14.
Have you ever experienced conflict with a co-worker? How did you resolve the situation?
Give the hiring manager an example of a time that you experienced conflict with a co-worker. What was the resolution, and how did you get there? Be careful to not become negative or speak poorly of anyone.

Rachelle's Answer
"Last month I had a conflict with a co-worker who was not abiding by the company's safety regulations. I brought it up and this particular individual became very defensive. I walked away from the situation and the next day, he apologized for overreacting. He committed to put safety first, which was great."
15.
Do you hold a Journeyman license?
This answer can be very simple and to the point.

If you do hold a Journeyman license: "Yes, I obtained my Journeyman license in 2006. All of my tickets and certifications are up to date."

If you do not hold a Journeyman license: "I aim to obtain my Journeyman license in the next 8 months. Asides from that, all of my required certifications are up to date."
