Foreword:
Nowadays, many companies require the use of "hand-tearing code" during interviews to test candidates' coding abilities. Do you think that hand-typing code can reflect the true basic strength?
Topics in this issue:
1. Do you think tearing code by hand is a basic skill for programmers?
2. Why is "hand-tearing code" used to test programmers' abilities?
3. What common hand-shredded code problems do you know?
Hand-shredded code, simply put, refers to writing code purely by hand without the help of an IDE (integrated development environment). This is often used as a test method in interviews. Here is my opinion on this topic:
-
Is tearing code by hand a basic skill for programmers?
-
not completely. Hand-shredding code can indeed test a programmer's coding proficiency and basic skills, but programming is not just code, but also includes logical thinking, problem-solving skills, project experience, and the ability to work with a team, etc. Moreover, in real work, we all rely on IDEs and other tools to improve efficiency. Hand-shredding code is not the standard for daily work.

Why is "hand-tearing code" used to test programmers' abilities?
-
Basic skills test : Hand-tearing code can quickly test the applicant's basic programming skills. If a programmer cannot write basic code without an IDE, there may be a problem with his basic skills.
-
Logical thinking ability : Without the help of IDE, candidates need to rely more on their own logical thinking ability to solve problems.
-
Ability to face pressure : Hand-shredding code during interviews is often accompanied by time pressure and the interviewer's observation, which can also examine the candidate's performance under pressure.
-
Filtering : For large numbers of applicants, using shredded coding as an initial screening method can quickly determine which candidates are worthy of further interviews.
-
-
What common hand-shredded code problems do you know?
-
Algorithm questions : such as reversing linked lists, binary tree traversal, array and string operations, etc.
-
Data structure questions : such as implementing a stack, queue, hash table, etc.
-
System design : Although not exactly hand-shredded code, it may require designing a system or architecture on a whiteboard.
-
Programming language related : such as writing a simple Python generator, Java multi-threaded code, etc.
-
Database related : handwritten SQL queries.
-
Overall, shredding code is an effective interview tool, but it should not be the only criterion. The candidate's other abilities and experience are equally important. For candidates, even if they rarely tear code by hand in daily work, they should practice frequently to maintain the basic skills of programming.
