Coding interviews at the best tech companies are highly competitive and arduous to crack. They can put you to the test even if you’re an experienced programmer. To ace coding interviews at FAANG+ companies, you need to be a great problem solver.
You need to diligently devote yourself to solving as many coding interview questions as possible. The questions we’re referring to here are problem-based questions in core data structures and algorithms. The problems asked at interviews are sometimes significantly challenging, meaning that if a solid strategy isn’t in place, you’re unlikely to make the cut.
The reason that FAANG+ companies ask tricky core DSA problems in coding interviews is to hire engineers who can find tech solutions to real-world problems through their fundamental ability to use programming and software to create solutions.
Knowing how to solve tricky coding interview questions requires dedicated effort backed by a good, sound strategy. To help you prepare for your next coding interview, we’ve compiled this list of the most common coding interview questions asked at FAANG+ interviews. These coding interview questions are around various topics fundamentally pertaining to core data structures and algorithms.
Having trained over 11,000 software engineers, we know what it takes to crack the toughest tech interviews. Our alums consistently land offers from FAANG+ companies. The highest ever offer received by an IK alum is a whopping $1.267 Million!

Coding interview questions are a crucial part of FAANG interviews. Questions and problems asked at these interviews are typically in the range of medium to hard on Leetcode. Practicing as many coding problems is absolutely crucial if you wish to set yourself apart from the competition.
More than practicing a certain number of problems, it is important to identify patterns in solutions and use similar patterns to solve new problems.
Let’s look at some popular coding interview questions asked at top companies to help you understand the type of problems to expect at FAANG coding interviews.
Google has a notoriously competitive interview process that filters in barely 2% of engineers who apply. Google’s coding interview essentially evaluates your knowledge of core data structures and algorithms.
Let’s take a look at some sample Google coding interview questions:

Q1. What topics should you prepare to solve coding interview questions in a technical interview?
To solve data structures interview questions, you must be thorough with the following concepts - arrays, strings, linked lists, recursion, hash tables, graphs, trees, and dynamic programming.
Q2. How many coding interview rounds are there in FAANG interviews?
Interviews at FAANG companies typically have 2-3 coding interview rounds. The first two rounds are usually technical screening rounds.
Q3. How long should you ideally prepare for FAANG coding interviews?
As a rule of thumb, it is crucial that you start preparing for your coding interview at least 6 weeks before your interview.
Q4. Are coding interview questions asked at domain-specific tech interviews?
Yes, most domain-specific tech interviews, such as ML interviews, testing interviews, cloud interviews, and web developer interviews, have mandatory coding rounds where your knowledge of programming concepts, core data structures, and algorithms is evaluated.
Q5. How long do coding interview rounds last at FAANG companies?
Coding interview rounds typically last 30-40 minutes. Recruiters mostly aim to evaluate your approach to problem-solving and your ability to write error-free code.
