interview record

2022.11.08

Today I had an interview with 钜泉光电（上海）.co, which made me very stressed.
He asked me so many questions that I couldn't answer well, like:
"What is the starting process of ARM MCU?
What is the violated variable in the programming language C?
What if I free a memory without a certain size.
How do the I2c and SPI protocol exactly works?
How did the USB driver mount?"

When I started to enter the employee market, I felt comfortable with my job career. Now I have a completely opposed opinion. I find out that I was stuck in a career trick.

I spend too much time on other things instead of the challenging technology field which makes me weak in job competition.

I was comfortable with my situation of dealing with easy work and getting high pay.

Now it's time to start moving.
