Recently, I worked with a seasoned developer who aced two JavaScript questions in his technical interview but completely froze on a basic SQL question. I was administering a small technical test via screen share, and I watched in real time as his confidence just evaporated on what should have been a straightforward query. When we debriefed afterward, his response was pure disbelief: “I can’t believe it was so simple! I knew it all along.”<\/p>\n
This scenario plays out everywhere, every day. Brilliant engineers overthinking their way out of correct answers.<\/p>\n
\u2022 The Problem: Interviews test totally different skills than your actual job – problem-solving under pressure vs. the deep expertise you use daily<\/p>\n
\u2022 Common Traps: Algorithm obsessions, getting so attached to your solution you won’t take hints, and going completely silent instead of thinking out loud<\/p>\n
\u2022 The Fix: Just start simple – seriously, resist the urge to show off with complex solutions right away<\/p>\n
\u2022 Game Changer: Record yourself doing 5 mock interviews<\/strong> and watch the transformation (it’s honestly pretty amazing)<\/p>\n \u2022 Communication Wins: Talk through your thinking – it’s like having a conversation about the problem<\/p>\n \u2022 Take Action: This week, record yourself solving one problem while talking through your approach (trust me, it’s eye-opening)<\/p>\n \u2022 Free Resources: Places like Pramp<\/a> and books like “Cracking the Coding Interview”<\/a> actually help<\/p>\n Look, interviews are just weird compared to actual work. Think about it – at your job, you’ve got:<\/p>\n But interviews? They flip all of that upside down. Suddenly you’re solving problems under pressure across random topics you might not have touched in months. No wonder your brain starts overthinking everything – a simple problem becomes this quest for the “perfect” solution.<\/p>\n Now, there are exceptions to this rule. Consulting roles and positions that require very specific languages or skill sets often do test you on exactly what you’ll be doing day-to-day. If you’re a Fortran developer applying for a scientific computing role, you’ll get Fortran questions. But if that same skilled developer applies for a modern web development position and gets grilled on NextJS components and React hooks, that’s the more typical mismatch we’re talking about.<\/p>\n But for most general software development roles, the interview process is really testing something different: your ability to think through problems methodically, communicate your reasoning clearly, and adapt to unfamiliar challenges without panicking.<\/p>\n Here are the patterns I hear about repeatedly from CTOs and VPs after interviews:<\/p>\n The Algorithm Obsession: Candidates try to memorize every advanced algorithm instead of solving the problem with basic, practical approaches.<\/p>\n The Perfectionist Trap: Candidates become so in love with their solution that they won’t take hints about different approaches, even when stuck.<\/p>\n The Shutdown Response: Instead of asking probing questions, candidates simply say “I don’t know how to do this” and give up without attempting the problem.<\/p>\n The Silent Struggle: Working in complete silence instead of talking through their thought process.<\/p>\n The False Confidence Phenomenon: Here’s a recruiting reality – candidates who leave saying “I aced that interview!” often get the harshest feedback. Sometimes interviewers don’t want to correct someone mid-interview, so they let candidates finish their flawed solution. The mismatch between candidate confidence and actual performance is startling.<\/p>\n From my experience getting feedback from CTOs and VPs, these patterns happen more often than people realize. The irony? These same engineers do practical, elegant work every day. But interview environments can turn even the sharpest minds upside down.<\/p>\n You’re not trying to memorize every algorithm – that’s impossible. Instead, train your brain to operate effectively under interview constraints:<\/p>\n Follow this pattern every time: 1. Restate the problem in your own words 2. Identify the core challenge you need to solve 3. Propose your approach at a high level 4. Code the solution while explaining each step 5. Test with examples to verify correctness<\/p>\n Okay, this might sound awkward, but recording yourself doing mock interviews is honestly magic. You’ll probably cringe at the first one (we all do), but by the fifth recording, you’ll sound like a completely different person.<\/p>\n Find Someone to Practice With: Maybe a colleague, a friend, or someone from one of those practice platforms. Even just recording yourself alone helps a ton.<\/p>\n Make It Feel Real:<\/p>\n Focus on One Thing Each Time:<\/p>\n When you’re reviewing, ask yourself:<\/p>\n The transformation is honestly pretty amazing to watch.<\/p>\n Interviews aren’t just testing your coding ability \u2013 they’re evaluating whether you’d be someone they want to work with every day.<\/p>\n Practice explaining your past work in concrete terms:<\/p>\n Give specific answers with clear action plans:<\/p>\n If you have them, side projects demonstrate passion and initiative:<\/p>\n While staying focused on our core message about overthinking, it’s worth noting that different interview formats require slightly different approaches:<\/p>\n Coding Challenges: Start simple, think out loud, test your solution with examples<\/p>\n System Design Discussions: Focus on high-level architecture first, drill down into details only when asked<\/p>\n Debugging Exercises: Read the code carefully, ask clarifying questions about expected behavior, work systematically from inputs to outputs<\/p>\n Take-Home Projects: Follow the requirements exactly, write clean and readable code, include a README explaining your approach<\/p>\n Here’s the thing about interviews – they have their own weird rules, and pretending they don’t is just going to frustrate you. Smart people struggle with interviews not because they can’t do the job, but because nobody taught them how to play this particular game.<\/p>\n Your skills aren’t going anywhere. You just need to get better at showing them off in this artificial, high-pressure situation.<\/p>\n Remember: interviews don’t test whether you’re good at your job – they test whether you’re good at interviews. Stop trying to be perfect. Start trying to be practical.<\/p>\n Ready to put these strategies into action?
