😱 The single worst moment of my life was the moment I was born. However, as a software engineer, I've faced even worse challenges during technical interviews.

🎢 If you survive tutorial hell before the age of 25 and impress the algorithms that read your resume, you enter a high-stakes game with a six-figure salary on one side and uncertainty on the other.

🧠 In today's video, you'll experience the psychological rollercoaster of a technical interview and learn secrets to high-pressure problem-solving.

💻 After a year of #learn to code, I finally landed an interview with a big tech corporation. I prepared with dozens of leak code questions and half-finished courses.

📞 During the interview, I was asked to solve the classic FizzBuzz problem: print numbers from 1 to 100, replacing multiples of 3 with "fizz", multiples of 5 with "buzz", and multiples of both with "fizzbuzz".

🤔 I initially panicked but realized I could break the problem down into conditions and use a flowchart or pseudocode to clarify my approach.

📝 I decided to use a traditional for loop for better performance and focused on explaining my thought process out loud, following the ABC rule: Always Be Chatting.

🔍 I learned that using the modulo operator is essential for checking multiples, and I adjusted my code to print results on a single line.

⚙️ I also explored how to handle additional conditions and improved my code's scalability by mutating a variable instead of using multiple checks.

📈 When asked about performance, I described it as linear time complexity or O(n) for an infinite game, but simplified to O(1) for the 100-step game.

🎉 After an intense hour, I was offered a job with a $400,000 salary and remote work options, only to have the offer rescinded due to a hiring freeze.
