Preface
Yesterday, I interviewed with a company and the conflict in values made me uneasy.
The interviewer is very good at technology, he can be a perfectionist and seems to find a solution no matter what problem he is faced with. I was shocked by his ability and felt a little at a loss.
However, what I cannot agree with is that the interviewer takes overtime for granted. He even said some people wanted to do things better and volunteered to work overtime. I don’t deny this point of view, but taking overtime for granted and thinking it has nothing to do with the national system confuses me.
The interviewer asked me what I thought about working overtime, and I replied that I could work overtime when necessary, as long as the work was meaningful. He countered that some people think working for a boss is meaningless, so is all overtime meaningless? Of course I deny this view, but it makes me feel helpless that he measures others with his own views.
Then, I said that I can work overtime when I am busy, but it will not continue forever. Are there arrangements for periodic rest and adjustment? He replied that no, this state would remain until the company went public.
I'm speechless about this. Maybe this is the difference in values. It seems that if I don't work overtime, it means that I am inefficient at work.
What makes me sad is that it may be our peers who make us work overtime.
