After the Meituan interview was hung up, I spent a few months sorting out these interview questions

Preface

It’s been a few months since the interview at Meituan was hung up, and now I’m still in a long time to be unable to calm down, but I can only blame myself, I don’t have strong technical skills, and I didn’t prepare in advance. I can only stay after the interview is hung up. Tears of regret (the water of West Lake, my tears), and then doing things to mend the situation, I don't want you to be like me, so I will share my interview experience with you, and hope that everyone will stop following my old ways.

 

 

To be honest, it’s a bit nervous to go to the US Mission for an interview

Meituan side

1. Self-introduction, many of the questions are asked around my resume

2. Detailed Thread Pool

3.Java virtual machine model introduction

4. New generation promotion strategy

5. The garbage collector used

6. New features of JAVA11

7. Hashmap is particularly simple introduction

8. MySQL's ACID and redolog undolog binlog

9. Problems encountered by the project

10. Class loading

11. Briefly talk about Sychronized and JUC

12.Sychronized scope

13. Views on the abnormal system

14. For an insert that does not report an error, how do you troubleshoot the error

15. Writing questions

1. Regular SQL query of results

2. Find PI

3.double check的singleton

4. Palindrome skewer

Two sides

After one side was over, the interviewer asked me to wait. I thought the interview would be over today, but I waited for the second interviewer who was also technical.

1. Introduce yourself and introduce the project process

2. The difference between process and thread

3. The difference between Synchronized and Lock

4. Transaction isolation level and implementation principle, what should I do if mysql locks up?

5. Java's garbage collection mechanism

6. How much do you know about the thread pool and what are the parameters of the thread pool?

7. HashMap principle

8. Three questions were asked:

• • There are 100 bottles of liquid, one of which is poison. A mouse will die a week after drinking the poison. In a week, how many mice are needed to determine which bottle is the poison?

• • Code to achieve the reversal of the linked list

• • An integer array is in ascending order and then in descending order. For an integer k, return its index in the array, and return -1 if it cannot

to sum up

For programmers, the educational requirements are already quite relaxed, so for programmers, the starting line is the same, there is no offer that can't be taken, only the ability to be hard-hearted enough. So I didn’t have it this time because my technical ability was not strong enough.

Then I spent some time sorting out some of the interview questions that big companies must ask to share with you, I hope everyone can interview, I plan to fight with Meituan next year, and I must get an offer from Meituan!

Conclusion

Although I failed to face Meituan this time, I hope that you can use the interview questions I compiled to go to Dachang. Finally, I hope everyone can give me a compliment and support! thank you all!
