How to practice coding for an interview?
Set a Structured Study Plan
Assess Your Current Skills
Start by figuring out where you stand. Identify your strengths and the areas you need to work on. This helps you focus your efforts where they’re needed most.
Create a Schedule
Consistency is key! Allocate specific times each day for coding practice. Whether it’s an hour in the morning or evening, sticking to a schedule keeps you on track.
Master the Fundamentals
Data Structures and Algorithms
Make sure you understand the basics like arrays, linked lists, stacks, queues, hash tables, trees, and graphs. Also, get comfortable with essential algorithms such as sorting, searching, recursion, and dynamic programming.
