A few days ago during an interview, I asked a question: "If there is a consecutive holiday, do the on-site technicians usually arrange overtime?"
The interviewer might think this is just a work detail, but for a production supervisor, I feel it is actually a very important question.
Because every production supervisor works in a different company, with different production methods, management systems, and on-site cultures. Even something like "whether to schedule overtime during consecutive holidays" can have completely different answers.
When I worked in the steel industry, consecutive holidays usually involved arranging at least one or two days of overtime for on-site foreign workers. For a production supervisor, this was actually a great time to utilize, because normal workdays have fixed production schedules. During holidays, when other departments are resting and order demands are less fragmented, it was possible to get ahead on some progress.
So back then, I would discuss in advance with on-site supervisors which projects were suitable for holidays, how much manpower was needed, and how much volume could be completed, then let the site arrange the personnel. This kind of overtime was not simply "staying because work cannot be finished," but treating it as a usable production resource in the schedule.
After moving to the electronics industry, the approach was different. I would first look at capacity. If the schedule showed a certain process was overloaded, overtime would be planned in advance. I would discuss with the production line supervisor which times needed overtime and which work orders could be scheduled earlier, instead of suddenly realizing we were running out of time close to the deadline.
But in the metal furniture industry, holiday overtime was not a "default will happen" option. It required first discussing with the supervisor and submitting an application in advance.
Three companies, all with production supervisors facing deadlines and capacity, yet completely different approaches. This is why I now ask more detailed questions during interviews.
When I first started working, interviews felt more like the company choosing people. They would ask if I could do something, what experience I had, and what I could accept. I answered questions, showed my experience, and waited for their decision. But after working at several companies, I began to realize that interviews are also my chance to understand the company.
Especially in a production supervisor role, many things look similar on the job posting: arranging production, tracking progress, managing materials, controlling deadlines, coordinating the production line. It seems every company does the same things. But only after joining do you realize how much the actual "methods" can differ.
Some companies allow advance overtime planning, while others require layered approvals. Some give on-site teams a lot of autonomy, while others need production supervisors to arrange everything beforehand. Some want production supervisors to identify capacity risks early, while others prefer handling problems only after they occur.
These differences often determine whether a job is suitable more than the few lines of job description.
Because what production supervisors fear most is actually "assuming"—assuming capacity will be sufficient, assuming materials will arrive on time, assuming the site can do overtime, assuming the next process still has time, assuming manpower can be arranged during holidays—only to find everything piled up. So what production supervisors really need to do is not just finish today's schedule, but think ahead: "If things do not go as planned, do I have other arrangements?" Whether to schedule overtime during holidays is just one small example.
What really matters is whether the company has a system that allows production supervisors to plan ahead, and whether there is enough communication space for them to raise potential issues before they happen.
Now during interviews, I also gradually ask these questions clearly. Not because I am afraid of work, but because I have learned that much workplace pain does not come from the work itself, but from "not knowing how things can actually be handled."
With over five years of production supervisor experience, I increasingly understand that the value of a production supervisor is not putting out fires after problems occur, but leaving a path for them in advance. So when looking for my next job, I am not just looking for a role "I can do," but confirming whether the company's production methods allow me to truly apply this experience.
After all, a production supervisor's job is to make reasonable arrangements and preparations. Whether a job suits you sometimes lies in those seemingly minor questions asked during the interview. This may also be the insight I gained after years as a corporate worker.
