The pursuit of jobs at the world’s largest technology companies has never been fiercer. Facebook, Amazon, Apple, Netflix, and Google — collectively known as FAANG — remain aspirational employers for millions of software engineers. Their hiring process is renowned for its difficulty, demanding not only technical expertise but also the ability to think clearly under pressure. Cracking the Code: How to Solve FAANG-Level Problems Like a Senior Developer has become both a challenge and a career-defining milestone for candidates across India and the world.
Why FAANG-Level Problems Matter
The hiring model at FAANG companies has set the global standard for coding interviews. According to Glassdoor, these firms receive hundreds of thousands of applications each year, with acceptance rates often under 2%. The questions are not designed to be solved by memorisation. Instead, they evaluate how engineers deconstruct complex problems, communicate their reasoning, and balance efficiency with clarity.
“We want to see how candidates think, not simply if they can recite an algorithm,” said Meera Iyer, a senior recruiter at Google India, during a panel hosted by the NASSCOM Future of Work Conference earlier this year.
How the Format Evolved
In the early 2000s, technology firms often relied on abstract puzzles. Candidates were asked questions such as “How many golf balls fit inside a school bus?” The aim was to test creativity, but the relevance to real-world coding was limited. Over time, this approach was replaced by structured algorithmic challenges. Today, FAANG interviews are rooted in coding platforms, whiteboard sessions, and system design problems that mimic actual engineering scenarios.
This evolution reflects a broader shift: companies realised that strong problem-solving and coding fluency are more predictive of success than clever answers to riddles.
How Senior Developers Approach the Interview
Pattern Recognition Over Memorisation
Senior developers distinguish themselves by recognising patterns in problems. A sequence optimisation may call for a sliding window. Pair-finding tasks often rely on two pointers. Optimisation under constraints typically points to dynamic programming. This pattern-based approach allows candidates to adapt quickly to new variations.
“Senior developers succeed because they identify the underlying structure of a problem and map it to a known solution strategy,” explained Rahul Agarwal, author of Cracking the Interview Code, in comments to Reuters.
Structured Thinking and Communication
Technical excellence alone is not enough. FAANG interviews require candidates to articulate their reasoning. A common practice among senior developers is to narrate thought processes aloud, weigh trade-offs, and test edge cases.
This mirrors day-to-day software engineering. “Writing code is only part of the job. Explaining, defending, and refining decisions in a collaborative environment is equally important,” said Dr. Kavita Menon, a computer science lecturer at the University of California, Berkeley.
The Candidate Experience
For many, FAANG interviews are life-changing. Arjun Patel, a Bengaluru-based engineer, described his experience joining Amazon after multiple failed attempts. “I treated each rejection as feedback. By my third try, I had shifted from memorising problems to mastering patterns. That made the difference,” he told The Hindu Business Line.
Similar accounts are reported across India, where engineers see FAANG offers as a passport to global opportunities and compensation levels unmatched by most domestic firms.
Global Competition and Influence
While FAANG companies dominate attention, their interview model has spread widely. Microsoft, ByteDance, and several European startups have adopted comparable processes. The model has also influenced Indian firms such as Flipkart and Zomato, which use algorithm-heavy interviews for technical roles.
Recruiters argue this reflects the competitive nature of the technology labour market. However, critics worry it sidelines candidates with practical engineering skills but weaker algorithmic training.
Training and Preparation
Bootcamps and Online Platforms
A multi-million-dollar industry has developed around FAANG interview preparation. Platforms such as LeetCode, HackerRank, and Interview Kickstart provide libraries of practice questions and mock interviews. India has seen rapid growth in companies like Scaler Academy, which reported a 70% increase in enrolments between 2020 and 2024.
Common Pitfalls
Experts caution against overemphasis on rare, “hard” problems at the expense of fundamentals. “Many candidates can solve exotic graph problems but stumble on arrays or strings under time pressure,” said Prof. A.K. Sharma of IIT Delhi.
Criticisms and Calls for Change
Not all voices agree the system is ideal. Researchers at Stanford University’s Human-Centered AI Institute argue that these interviews may not reflect daily work, which often emphasises system architecture, collaboration, and long-term maintainability.
Others highlight accessibility issues. Candidates from under-resourced institutions may struggle to compete, raising concerns of equity.
Still, industry leaders defend the format as a fair stress test. “Coding interviews are not perfect, but they reveal resilience and adaptability,” said Elena Gomez, a senior engineering manager at Facebook, in remarks to Bloomberg.
The Future of FAANG Hiring
Looking ahead, hiring practices may evolve. Several companies are experimenting with project-based interviews, where candidates build small applications over days. Artificial intelligence is also being introduced to screen applicants and detect plagiarism in solutions.
Yet, experts believe algorithmic problem-solving will remain central. “Even as formats change, the core skill of structured problem-solving will continue to define who succeeds at FAANG,” said Dr. Menon.

Conclusion
FAANG interviews continue to symbolise the highest standard of technical hiring. While the process is demanding, the lessons extend far beyond the interview room. For aspiring engineers, the path to success lies not in memorisation, but in developing structured reasoning, mastering algorithmic patterns, and communicating with clarity. Senior developers show that these qualities, combined with persistence, can turn daunting challenges into defining career achievements.
