Introduction and Tips for Improving Coding Interview Skills
00:00
The speaker used to earn $5 an hour at a startup but managed to land a six-figure job at Amazon in under two years without a CS degree.
Three key tips for improving LeetCode skills are shared.
Tip 1: Practice how you'll interview by mimicking the real-world coding interview as much as possible, including timing yourself and voicing your thoughts out loud.
Tip 2: Focus on high ROI topics, such as arrays, strings, hash tables, and dynamic programming, which are commonly asked in coding interviews.
Tip 3: Learn coding patterns, which are proven techniques that can be applied to solve a wide variety of problems.
How to Practice for Coding Interviews
02:41
Allocate 4 to 6 weeks for prep, with 2 to 3 hours of practice 5 to 6 days a week.
Suggests treating interview prepping like a part-time job or side hustle.
Practicing with a friend and taking turns mock interviewing each other can be helpful.
Focus on High ROI Topics
05:25
Prioritize studying and practicing questions with a higher likelihood of being asked in coding interviews, such as arrays, strings, hash tables, and dynamic programming.
It's not necessary to solve hundreds of problems or tackle less commonly asked question types, but they should not be ignored completely.
Importance of Learning Coding Patterns
06:27
Coding patterns have been a game changer for the speaker in coding interviews.
They are proven techniques that, once learned, can be applied to solve a wide variety of problems.
Examples of coding patterns include the sliding window pattern for optimizing time and space complexity.
Studying with intent, focusing on one group of problems at a time, and practicing handwritten solutions can help in learning coding patterns faster.
Tech interview platform TechInterviews.io is recommended for learning coding patterns more effectively.
Conclusion
08:55
Learning coding patterns is essential for interview preparation.
It is recommended to focus on learning the key building blocks that underlie most algorithm problems.
TechInterviews.io is suggested as a platform to learn coding patterns more effectively.
