I'm still quite surprised , According to my career development plan ,35 Age is just a stage , Why care so much ？ He said ,35 After the age of, most of them have to leave their jobs and change careers , I can't do it in software testing . This conclusion once made me very depressed and angry , How did he come to this conclusion , Where is the data? ？

as if , Arranged by others 35 Year old destiny framework , We have to accept the same . Side 35 There are really many colleagues over the age of , Their accumulated work experience is practical , The technological moat and industry competitiveness are extremely high .
