The speaker explains how they quadrupled their salary by strategically preparing for coding interviews, focusing on building a library of behavioral stories, addressing technical knowledge gaps, and practicing mock interviews to reduce anxiety. They emphasize the importance of negotiation and targeted preparation, offering practical advice and resources for developers aiming to improve their interview performance and career prospects.

The speaker shares their personal journey from struggling with coding interviews to quadrupling their salary over several years, providing proof and credibility for their claims. They clarify that their advice is not aimed at those preparing for interviews at top tech giants like Google or Netflix, but rather for the majority of developers who face more typical interview scenarios. The speaker recounts their own failures, including panic attacks and embarrassing moments at companies like Google and Meta, emphasizing that improvement is possible with the right approach and mindset.

A key strategy the speaker adopted was building a library of personal stories to use during behavioral interviews. Instead of improvising answers, they documented experiences that demonstrated leadership, technical ability, and resilience. This preparation allowed them to confidently answer common behavioral questions and avoid failing that part of the interview, which is often overlooked but crucial for roles like engineering manager.

On the technical side, the speaker focused on identifying and addressing their specific knowledge gaps rather than trying to master everything. They tackled weak areas such as closures, prototypal inheritance, recursion, and React performance by building small projects and teaching the concepts out loud, a method known as the Feynman technique. This hands-on, explanatory approach helped solidify their understanding and made them more confident in technical interviews.

To overcome interview anxiety, the speaker practiced by doing numerous mock interviews on platforms like pramp.com and interviewing.io. Repeated exposure to the interview environment made the process feel routine rather than intimidating, significantly reducing nerves. They also attended programs like Interview Kickstart, which, while focused on big tech prep, boosted their confidence and technical skills for other types of interviews.

Finally, the speaker highlights the importance of negotiation and shares a simple but effective tactic: always ask for 10-20% more than the initial offer without over-explaining. They stress that interviewing well is a high-leverage skill for software developers, even if the process is imperfect or unfair. Their advice is to prepare strategically, practice with real people, research likely questions, and not dwell on rare or unrepresentative failures.
