Autumn Trick Time Planning: A Knowledge Summary and Interview Reflection
As the autumn leaves change colors, I reflect on the journey of preparation that led me to secure a job offer from a medium-sized Internet company. This article is a summary of my knowledge acquisition, interview questions, and the mental shift I experienced throughout the process.
I. Stock of Knowledge
In the months leading up to the interviews, I focused on building a strong foundation in computer science. I reviewed the basics, including:
- Algorithm: Proved safety, algorithmic thinking, and problem-solving skills. I studied classic problems like sorting, dynamic programming, and greedy algorithms.
- Data Structures: Mastered stacks, queues, linked lists, binary trees, B-trees, and red-black trees. I also learned about the STL and C++.
- C++: Familiarized myself with pointers, virtual functions, static modifiers, const, and reference design patterns.
- Computer Network: Studied TCP, UDP, HTTP, DNS resolution, and the process of resolving domain names.
- Database: Learned about SQL statements, integrity constraints, B-tree storage, relational algebra, and database recovery techniques.
- Operating System: Focused on deadlocks, process management, and memory management.
- Design Patterns: Explored the Singleton pattern, Factory pattern, Abstract Factory pattern, Adapter pattern, and Decorator pattern.
II. Interview Questions
During the interview process, I encountered a variety of questions, which can be categorized into six types:
- Algorithm: Questions that tested my problem-solving skills, such as sorting, dynamic programming, and greedy algorithms.
- C++: Questions that assessed my understanding of C++ fundamentals, including pointers, virtual functions, and static modifiers.
- Big Data: Questions that probed my knowledge of data distribution, replication, consistency, and fault tolerance.
- Algorithmic Thinking: Questions that required me to think creatively and solve problems using algorithms.
- System Design: Questions that tested my ability to design and implement complex systems.
- Behavioral Questions: Questions that evaluated my problem-solving approach, communication skills, and teamwork experience.
III. The Change of Mind
As I progressed through the interview process, I experienced a significant shift in my mindset:
- June to September: I was in a normal review phase, with no major changes in my approach. I participated in internal pushes and realized the importance of practicing algorithmic thinking.
- September: I entered the giant pen interview phase, where I faced more challenging questions and realized the need for handwritten code. I focused on practicing classic algorithms like DFS, BFS, and DP.
- October: I entered the internet start-ups phase, where I interviewed with more than a few companies. I realized the importance of being prepared and having a solid understanding of computer science fundamentals.
IV. Summary
In conclusion, the autumn trick time planning was a long and challenging journey. I learned to stick to my goals, continue learning, and be prepared for the unexpected. I hope that my story will inspire others to pursue their dreams and never give up.
