Each tech giant had its own unique interview process, but they had some commonalities. Here is a cool infographic to get you some tips on how to impress in a job interview.
Alphabet (Google): The Algorithmic Playground
Her Google interview started with an algorithmic coding challenge. She was asked to solve a problem on a shared coding platform. The key was to write clean, efficient code and explain her thought process. The interviewer delved into her problem-solving approach, emphasizing both time and space complexity.
Tip 3: Communication is Key My friend learned that communication was crucial. She articulated her thoughts clearly, explaining her code step by step. This not only showcased her problem-solving skills but also her ability to collaborate.
Apple: A Blend of Technical and Behavioral
Apple’s interview process included both technical and behavioral assessments. My friend was asked about her previous experiences, projects, and how she handled challenges. The technical part involved coding challenges related to system design and problem-solving.
Tip 4: Master Behavioral Questions In addition to technical prowess, She recognized the importance of preparing for behavioral questions. She shared stories that demonstrated her teamwork, leadership, and problem-solving abilities.
Amazon: A Mix of Everything
Amazon’s interviews were a mix of technical problem-solving, system design, and code debugging. My friend found herself exploring a wide range of skills.
Tip 5: Be Adaptable My friend embraced adaptability. Each interview required a slightly different approach, and she was ready to switch between problem-solving, system design, and debugging seamlessly.
The coding interviews were tough, but she was ready. She was able to answer all of the questions and even got some compliments on her problem-solving skills.
After a few weeks, she received the news that she successfully cleared the interviews for all three companies. It was a phenomenal feeling for her! She had finally achieved her dream of working for a big tech company.
Chapter 4: Lessons Learned
She learned a lot from my experience preparing for and taking the coding interviews at Google, Apple, and Amazon. Here are some of the most important lessons learned:
- Preparation is key. The more you prepare, the more confident you will be during the interviews.
- Practice makes perfect. The more you practice solving coding problems, the better you will become at it.
- Don’t give up. The coding interviews are tough, but they are not impossible. If you keep practicing and never give up, you will eventually succeed.

Chapter 6: Is There a Common Strategy to Tackle All the Companies or Take Specific Approaches?
There is a common strategy that you can use to tackle the coding interviews at all three companies. However, there are also some specific approaches that you can take for each company.
For example, Google’s coding interviews are known to be more difficult than Apple’s or Amazon’s. So, you may want to spend more time preparing for the Google interview.
Through her experiences, My friend was able to identify the following strategies that applied to all three tech giants:
Tip 6: Time Management She learned to manage her time effectively during interviews. She allocated time wisely, ensuring she didn’t spend too much on any single problem.
Tip 7: Don’t Panic, Think Aloud During challenging problems, She remembered not to panic. Instead, she thought aloud, explaining her approach and seeking feedback from the interviewer.
Tip 8: Continuous Improvement After each interview, She sought feedback and analyzed her performance. She identified areas for improvement and refined her strategy for the next one.
Watch Out Some of the Scientific Methods
Yes, there are several scientific methods that can help you crack coding interviews. These methods are based on principles from psychology, cognitive science, and computer science, and they can help you improve your problem-solving skills, communication skills, and overall approach to coding interviews.
Here are a few examples of scientific methods that can help you crack coding interviews:
a) Cognitive load theory
This theory suggests that there is a limited amount of information that our brains can process at once. When we are trying to learn or solve a problem, we can overload our cognitive systems if we try to do too much at once. To avoid cognitive overload, we can break down complex problems into smaller, more manageable steps. This approach can be particularly helpful when solving coding problems during an interview.
Metacognition is the ability to think about our own thinking. When we are metacognitive, we can become aware of our own strengths and weaknesses, and we can develop strategies for improving our performance. In the context of coding interviews, metacognition can help us identify areas where we need to improve our problem-solving skills or communication skills.
c) Growth mindset
A growth mindset is the belief that our abilities can be developed through effort and learning. People with a growth mindset are more likely to persevere in the face of challenges, and they are more likely to seek out opportunities to learn and grow. In the context of coding interviews, a growth mindset can help us overcome our fears of failure and motivate us to keep practicing and improving.
d) Active recall
Active recall is the process of retrieving information from memory without the aid of cues. It is a more effective way of learning than passive recall, which involves simply re-reading or re-watching material. Active recall can be used to improve your knowledge of coding concepts and algorithms, which will make you more prepared for coding interviews.
e) Spaced repetition
Spaced repetition is a way of learning where you review information more and more, but with increasing time in between. It’s a helpful method, especially for remembering words and their meanings. It can be used to review coding concepts and algorithms, which will help you keep them fresh in your mind for coding interviews.
In addition to these specific methods, there are a number of general scientific principles that can be applied to coding interviews. For example, the importance of getting enough sleep, eating a healthy diet, and exercising regularly has been well documented. These factors can all affect your cognitive performance and your ability to perform well in a high-pressure situation like a coding interview.
By applying scientific methods to your preparation, you can increase your chances of success in coding interviews and land your dream job in the tech industry.
