Preface
I graduated the year before last. After graduation, I have been working as a salted fish with a salary that is neither high nor low. I resigned this year due to the epidemic and some other reasons. After resigning, I have been reviewing and writing questions. In September, I got a byte interview opportunity through friends' internal massage, a total of 3 rounds of technical + hr interviews, let me share my experience with you!

I finished writing, I still have time, so I asked which language I am most familiar with. I said Java
and slapped on the keyboard. It is estimated that I will search for the exam questions on the spot. . .
After 30s, my eyes suddenly light up and ask, copy a = "xyz", a = new String(xyz) What is the difference? Harm, I forgot, I thought there was no difference in the heap, so I said there was no difference.
As soon as the uncle's face changed, he felt half cold.
He continued to ask you to think about it again. I really forgot at the time. I thought for a while and said I
did n’t know. Then he became unhappy and asked me what would you do with Java?
I said I would Spring
and then he said it would be over???
At last
This article is shared with friends who need to interview and brush questions, and I wish you all the best offers you want. This information mainly contains a lot of knowledge points, probably as follows:
Generally speaking, the code level is not very demanding, but the basic knowledge asks for real details, and it is impossible not to rely on memorization. The above information is shared with everyone for free, I hope it will be helpful to you! I didn’t perform well on three sides and thought it was going to roll over, but in the end it passed without risk. After two days of offer, the team was developed by the Shanghai business center. Listening to their introduction, it seems that they are doing content review of all the apps of Byte. .
