this is not so much on the interview but how i portrayed myself during the interview. i told my recent employer i just finished school, i have the epa card, i know enough to know what i am basically looking at but i know i have a lot to learn. to make a story short a couple months later i was his apprentice, he hired two different people. both people during the interview portrayed them self as all that, both knew as much or less than i did after a couple months. they were fired. me and the boss talked about them, he said all i have is you.... i said at least i told you the truth, you knew what you got into. he laughed and agreed, honesty it was the best, and usually is.

That kind of attitude will get you a loooooong way down the highway of life. I've hired many guys like you over the years.
During my first interview with a commercial service company I literally had to take a 50-100 point written exam. Questions ranged from anything like others have listed, to me having to fill in a chart explaining what happens to motors, superheat, subcooling, compressors, temperatures, etc. whenever certain events occur. There were about ten of them. Examples: Clogged condenser coils, low charge, TXV bulb lose, etc... You have to fill out what happens to head pressure, suction pressure, superheat, subcooling, compressor amp draw, delta t's, etc. whenever the event listed occurs. It was really interesting and it actually made me think a bit. I wound up getting the job. I had studied one of my school books prior to the interview. It definately helped me out.
If you are applying at a facility that has only one type of chiller/boiler than call anyone and everyone you can to find out what they have and at least be familiar with what it is. I went on a interview once where they were running 150lb steam pressure with 3 different boilers. I work on high pressure steam boilers alot but had no clue how to answer some of there questions about how to run them all in balance. They also had absorption chillers which i never worked on but i still got offered the job. Its all about how you cary yourself and how you answer the questions. Just be a strait shooter and dont b.s anyone. None of us know everything but most of us know enough to figure anything out if we are motivated enough.
Today,you may also want to be sure your face book page, twitter, or any other internet dealings, are clean and not containing a bunch of crap. Many people loose their jobs or their applications are file 69'ed by the info you post.
I got a job offer a few weeks ago that I ended up not taking. Other than normal stuff I was asked if i had my tools with me. I said yes and i usually have at least some with me at all times and that when im working I always have them with me. The other 3 guys at my interview didnt have any, not even a screw driver in there car. He said they had lost a job offer before they even started. Ive also seen some ask about the refigeration cycle and the one i dread is they have you draw a line diagram of a fairly complex system. Im just starting out and just couldnt do that one and really still cant. For me personally I think that will always be a probelm question.
"What do you think it means to be a team player?" "What do you think your employment would contribute to this corporation?"

Also, the position im being interviewed for is a Refrigeration Maintenance Mechanic. I do have 5 years experience in the HVAC field, most of it is house hold cooling & heating installations/service. Im wondering if anyone would know typical questions that might be asked and how I should respond to them. I have a good idea as to questions that may be asked but any help is appreciated. Also as a side note, the interview is somewhat hands on from what I gathered which will include a walk through throughout the facility. Any feedback is appreciated. Thank you. Hello, From my side i can give only 1 advice.... do not get nervous, be brave...definately you will get selected. If you need any job description just visit our site: Job Description

I didn't have a refrigeration interview, but for a commercial job I was asked a couple questions. What is the function of a capacitor in a PSC motor? Explain the purpose and operation of a receiver controller in a pneumatic control system? I was grateful for the softball questions.
Good topic.

Thats why that is a great question. I see you were paying attention in school.
When I taught basic electricity I took a shop vac, turned it on and took an amp reading. Then I wrote it on the board, Then with the amp probe off, I put my hand over the end of the hose and had everyone in the class guess the amp draw. I wrote each guess on the board. Almost 100% guessed higher. Then I let someone check amps with the hose closed off, it was a fun little demonstration.
