. It took him two days to submit the code after he finished the development and passed the test. Who knows their project manager, after reading the code, ran to his desk and patted him and said, "How did you learn the data structure? What database does this real-time queuing module use? Isn't it enough to complete it in the memory. Change it now. It must be completed today and handed over to me early tomorrow morning ."
The food was so cold and sweaty
