How to prepare for company-specific coding interviews
Every company has a slightly different interview culture. Google is known for dynamic programming and graph problems. Amazon leans heavily on arrays, strings, and BFS/DFS. Meta loves two-pointer and sliding window questions. Knowing these patterns lets you prioritize your study time.
Start with the highest-frequency problems for your target company. These are the ones that show up again and again in real interviews. If a problem is marked “Very Likely,” you should be able to solve it cold, explain the time and space complexity, and handle follow-up variations.
Once you have the top 20-30 problems down, broaden to the underlying patterns. A company might rotate individual questions, but they rarely change the categories they test. If Apple asks a lot of tree problems, they will keep asking tree problems even if the specific question changes.
Finally, don't just solve problems silently. In a real interview, communication matters as much as the code. Practice explaining your approach out loud, or better yet, do a mock interview where an AI interviewer pushes back on your reasoning and makes you defend your choices.
