Design Engineer/Process Engineer was asked...April 19, 2016

Typical production questions - How do you handle conflict resolution, Then they want you to tell them how to fix their problem with lighting and ignition circuit failures, with no data, no specifications, no test data. - Production should stick to assembly related problems and not try to design the product. They are currently using Solid Works and Pro E software - "That's just the way things happened". Just a little FYI some companies have 4 to 5 different CAD packages. It come down to can they communicate with each other. They have no analysis software which speeds up product development by 30 to 40%. Projects typically take 12 to 18 months. The lab is a basic combustion lab, A gas line, regulator, hose, QD connector with a wet or dry volume meter and a combustion analyzer. This is typically what is found in 90% of labs across the country. You can't expect much, a fireplace or a stove is little more than a box with a burner in it. They are mostly for decoration and range from zero to 100% efficient but the heat is not regulated, turn on or off. The model shop is up to date and separate from the manufacturing operations. They want a 20% improvement in the product they are producing over their competitors. This made no sense since they are converting all product to the same as the AUTO manufactures (what metrics would you use?). One frame and several front grills and rear body styles. The factory looks just like an auto factory, conveyors going in several directions. Wet and dry paint lines, JIT (Just In Time) manufacturing. Suppliers making deliveries twice a day. They have project management problems - "Some use a spreadsheet and some use MS Project". Then they wonder why their having problems - No Consistency. Eng. Mngr. was pulled away from the interview over a dozen times during the process. Looks like you could have a stress heart attack by the time you're 40. Their spending most of their time putting out fires. Floor guided electric robots to deliver part to the assembly lines, but if one part is missing for an assembly the line stops - a little too much JIT thinking.

Problem resolution - Talk to the person and resolve the problem between us. If that doesn't work bring a manager into the meeting. When that doesn't work build the product (which are always under construction in the Eng. Lab) and show why the proposed solution will, or will not work. Proving one test is worth a thousand expert opinions. Less

Huntsman Corp

Name something you hated about a previous job.

1 Answers

I wouldn't say "hate" is appropriate, but I don't like when employees bad-mouth the company or our clients. I had one coworker who loved gossiping about how "stupid" someone was. I told her I thought it was a bad idea to do that, it made me uncomfortable, and I shut her down whenever she started to bring this up.. I thought it was unprofessional, harmful, and I figured if she's talks trash about people to me, she likely talks trash about ME to others. Less

What web site do I use?

1 Answers

It's not a question of the web site they are all integrated. The problem is thinking about what their looking for. HINT there are 48 areas called states across a big land mass (called america). Most have 3 to 4 possible locations that have a person with the type of experience their looking for. Most companies spend 6 to 12 months to find someone. A few have spent 4 years. One company surveyed 65 engineers and made only 4 offers and were turned down by all. Companies just don't think about what is important to the employee. Less
