Tech-Interview-Study

The study table of contents was made by referring to the songwonseok/CS-Study and the Gyoogle/Tech-InterView-For-Developer.
We aim for in -depth learning about each topic.

Part 1. CS Interview Questions/Answers

See the expected question before the interview and answer yourself and check the correct answer.

• Computer structure
• Data structure
• Db
• network
• Operating system
• Algorithm
• Web
• Software engineering

Part 2. CS Deep Dive

This is part of dealing with CS in depth when you have enough time.

Rules

Every 월요일 밤 9시 online study (excluding public holidays)
In the study, 모의 면접 , 피드백 and borrowers 주제 선정
Mock interviews are randomly selected on the same day so that the interviewer of the participants is higher.
Mock interview contents are combined by one in the interview

Withdrawal of three or more times.
Reason for Yugo | Eight Day coding test and interview, disease (certification required)
