Why do you want to go to Bytedance

Here’s why you want to remove bytes:

I want to accumulate experience in Dachang and learn new Internet technology in Byte. And I heard that byte atmosphere is very good, regardless of rank and title, even interns can participate in many projects, learn a lot of things.

The company also attaches great importance to staff training, there are many sharing meetings, theme training and so on, we can meet a lot of bigwigs. This is really great for newcomers!

Then there’s Byte’s famous foodie perk — three meals plus afternoon tea, unlimited snacks

Canteen dishes are very rich, all kinds of chicken, duck, fish, mutton, beef, seafood, and all kinds of soup. During the working hours, you can go to the tea room to have snacks. Afternoon tea is also abundant, such as Paris baguette And Wheat Hill KFC, puffs and pork floss grilled wings, as well as daily nuts, charcoal roasted nori, liang Pinshop, etc., snacks are very delicious ~




Here are some of the questions I’m going to face as I wade through the interview process


I made a mind map roughly according to the following structure:

1. JVM related

Runtime structure GC algorithm JVM tuning

2. Programming languages

Scala Java

3. Data structure and algorithm

Table, stack, queue tree hash priority queue sort high-level data structures

4. Concurrent programming

Java memory model basic tool lockless concurrency reactive tool

5. Micro services

Microservices design service governance

6. Middleware

Distributed cache message queue RPC

7. Database

Relational database NoSQL NewSQL

8. Machine learning algorithms

Recommendation algorithm

The JVM, Scala-related, concurrent programming, message queues and so on have all been carefully written; The Java language is too simple to learn, the data structure is a little bit of a look in my mind and I feel like I’ve been buried for a long time and suddenly I’m awakened, microservices-related recommendation algorithms; There are too many database-related things. There are too many problems with the byte algorithm, so you can focus on the algorithm knowledge


experience

In terms of why BYtedance can succeed, first of all, my basic knowledge is actually good. Although the interviewer in the second interview thought that MY basic knowledge is not good, in fact, I have made my thinking, structure and context clearly when I go deeper. Second, I have my own hit product. I don’t have to ask questions in interviews. When asked about Spring, Dubbo, Netty, Go, or reactive architecture, I am the hottest guy on the street!! Finally, relax, and you have nothing to lose if you don’t go, so you can be both humble and calm during the interview, so you can perform well.
