I went for an interview as a gauge technician today and was asked questions that left me confused.
Thread Content
When asked what patents the processes from his previous company were and in which country those patents were filed, he was unable to answer. Let me give a general description of the process flow; I finished quickly, but he kept saying to go on. I also asked what other materials there were; I thought things like compressed air and steam could be excluded, so as to make him think I didn’t know about these things. When the topic of thermocouples came up, I thought I should explain their working principle. Noting my hesitation, he said that thermocouples are generally used for measuring high temperatures, and I immediately added that thermocouples tend to have greater errors compared to thermal resistors. Speaking of flow meters, I was asked which ones measure mass flow rate and which ones measure volume flow rate; I couldn’t immediately recall which ones are used for measuring volume flow rate. He said it’s the orifice plate flow meter. They also asked me what the boiling point of acetic acid is and what its properties are; I can give a brief description, but I’ve forgotten the exact boiling point value, even though I knew it before. I was also asked about some terms I had never even heard of. In short, I feel that my knowledge is too limited and my preparation is insufficient; I need to put in a lot of effort to study*. I asked the HR department, and they said I passed the interview; I need to wait for further notice regarding the exact date I’ll start working. I’m a bit anxious. What do you all think?
In fact, I personally believe that an interview is not necessarily a test of a person’s technical skills; it is more of a test of their ability to handle situations.
The question is quite broad; there might be things you don’t know. No problem.
Sometimes, the people conducting the interviews don’t know much either. I heard that people try to show off in front of the interviewers at 1:30 or so. You’re right, and it’s something new; he’s never heard of it, so he thinks you’re wrong. Your explanations are of no use. Another thing is that the questions asked are not closely related to the industry; they are asked until you don’t understand them, thereby giving an excuse to pay you less.
The field of instruments is extremely broad and evolves very rapidly; continuous learning is necessary. So as long as you are willing to work hard and keep learning, there will be no problems.
These days, when many companies hire instrument technicians, they require not only experience in the specific field of instrumentation but also experience in electrical and equipment-related work. Professional theory tests are necessary, and knowledge of PID principles and data models is also required.
Hehe, the original poster is nervous. Actually, these things can all be understood by drawing parallels
It’s just showing off, to give you a taste of what’s to come :lol
Haha, it was the person in charge of mechanical, electrical, and instrumentation who interviewed me. He seemed like a nice guy. He mainly tested my familiarity with various processes, wanted to know what I had done in that area before, and he made sense – he wouldn’t cut my salary.
I know a little and have met the requirements, but I need to strengthen my learning going forward.
You’re asking so many questions; it seems like there’s even a technical aspect to them
