That Is the Skill Now."},"content":{"rendered":"\n<p class=\"wp-block-paragraph\">CoderPad&#8217;s <a href=\"https:\/\/coderpad.io\/survey-reports\/coderpad-state-of-tech-hiring-2026\/\" rel=\"nofollow noopener\" target=\"_blank\">State of Tech Hiring 2026<\/a>, a survey of roughly 650 developers and hiring leaders, found that <strong>66% of hiring leaders are looking for candidates who catch and fix AI mistakes<\/strong> \u2014 a larger share than any tool or language on the list. Meanwhile Stack Overflow&#8217;s 2025 Developer Survey put AI adoption at 84% and the number of developers who <em>highly trust<\/em> what it produces at 3%. Both things are true at once, and together they describe the job you are applying for: everyone generates code now, and almost nobody trusts it. The scarce skill is the review.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Key takeaways<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Using an AI coding tool is no longer a differentiator \u2014 84% of developers already do, so a founder assumes you did too.<\/li>\n\n\n\n<li>Trust is falling while use rises: Stack Overflow&#8217;s 2025 respondents put trust in AI accuracy at 29%, down 11 points in a year.<\/li>\n\n\n\n<li>A randomised trial found experienced developers were 19% <em>slower<\/em> with AI while believing they were 20% faster. The perception gap is the real risk.<\/li>\n\n\n\n<li>Build the review into your proof: know which lines you generated, what you rejected, and what you tested.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Everyone has the tool. That is exactly why it stopped being the skill<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The <a href=\"https:\/\/survey.stackoverflow.co\/2025\/ai\" rel=\"nofollow noopener\" target=\"_blank\">2025 Stack Overflow Developer Survey<\/a> recorded 84% of respondents using or planning to use AI tools, up from 76% a year earlier, with 51% of professional developers using them daily. In the same survey 46% said they actively distrust the accuracy of what those tools produce, against 33% who trust it and 3% who highly trust it. Stack Overflow&#8217;s own write-up put it plainly a few months later: <a href=\"https:\/\/stackoverflow.blog\/2026\/02\/18\/closing-the-developer-ai-trust-gap\/\" rel=\"nofollow noopener\" target=\"_blank\">trust fell to 29%, down 11 percentage points from 2024<\/a>, while usage kept climbing.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For a student that inversion is good news, because it tells you where the remaining value sits. Nobody is impressed that you prompted your way to a CRUD app; the founder reading your application did the same thing last Tuesday. What they cannot outsource is the part they are complaining about \u2014 the 66% of Stack Overflow respondents whose biggest frustration is &#8220;AI solutions that are almost right, but not quite&#8221;, and the 45% who say debugging AI-generated code eats their time.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">The measured cost of not reading what you shipped<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">METR ran <a href=\"https:\/\/metr.org\/blog\/2025-07-10-early-2025-ai-experienced-os-dev-study\/\" rel=\"nofollow noopener\" target=\"_blank\">a randomised controlled trial with 16 experienced open-source developers across 246 real issues<\/a> in their own repositories \u2014 projects averaging over 22,000 stars and a million lines of code \u2014 randomly assigning each issue to allow or forbid AI tools. The developers forecast a 24% speed-up beforehand and estimated a 20% speed-up afterwards. Measured, they were <strong>19% slower<\/strong> on the AI-allowed issues.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Read it carefully before drawing the wrong lesson. This was early-2025 tooling, sixteen experts, and their own large codebases; it does not prove AI makes everyone slower everywhere. What it establishes is that <em>developers cannot feel the difference<\/em> \u2014 they were wrong about their own speed by roughly forty percentage points, in the flattering direction. If experts with years of calibration misjudge this, a second-year student reviewing a generated file at 1am is not going to judge it by feel either. You need evidence: tests that run, a diff you read line by line, a timing you actually took.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"576\" src=\"https:\/\/tierones.io\/blog\/wp-content\/uploads\/2026\/09\/ai-coding-tools-students-screening-review-opt-1024x576.jpg\" alt=\"ai-coding-tools-students-screening-review\" class=\"wp-image-316\" srcset=\"https:\/\/tierones.io\/blog\/wp-content\/uploads\/2026\/09\/ai-coding-tools-students-screening-review-opt-1024x576.jpg 1024w, https:\/\/tierones.io\/blog\/wp-content\/uploads\/2026\/09\/ai-coding-tools-students-screening-review-opt-300x169.jpg 300w, https:\/\/tierones.io\/blog\/wp-content\/uploads\/2026\/09\/ai-coding-tools-students-screening-review-opt-768x432.jpg 768w, https:\/\/tierones.io\/blog\/wp-content\/uploads\/2026\/09\/ai-coding-tools-students-screening-review-opt-1536x864.jpg 1536w, https:\/\/tierones.io\/blog\/wp-content\/uploads\/2026\/09\/ai-coding-tools-students-screening-review-opt.jpg 1600w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">What the research actually says about beginners using these tools<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The honest answer is: less than either camp claims. The most-cited controlled study is Kazemitabaar and colleagues&#8217; <a href=\"https:\/\/arxiv.org\/abs\/2302.07427\" rel=\"nofollow noopener\" target=\"_blank\">CHI 2023 experiment with 69 novices aged 10 to 17<\/a>, working through 45 Python code-authoring tasks with half of them given access to an AI code generator. Access raised the completion rate 1.15x and scores 1.8x, and \u2014 the part usually left out \u2014 did <em>not<\/em> reduce performance on the manual code-modification tasks that followed, or on a post-test a week later.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">So the tool did not rot anyone&#8217;s brain in that setting. But notice what the design required: every authoring task was immediately followed by a task the participant had to do by hand. Nobody got to accept output and move on \u2014 which is exactly the failure mode in a student repository, where generated code goes in unread and stays there until an interviewer asks about line 40. The tool is not the problem. Skipping the second half of the loop is.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How this shows up in an interview<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Rules vary, so ask rather than guess. CoderPad&#8217;s 2026 data has 46% of companies allowing AI in assessments \u2014 some broadly, some with constraints \u2014 against 34% banning it outright and 20% deciding case by case. Karat&#8217;s <a href=\"https:\/\/karat.com\/engineering-interview-trends-2026\/\" rel=\"nofollow noopener\" target=\"_blank\">January 2026 report on 400 engineering leaders in the US, India and China<\/a> found 62% still prohibit AI in interviews while more than half of those leaders assume candidates use it anyway, and 71% say AI has made technical skills harder to assess. Note the direction of that anxiety: they are not worried that you are fast, they are worried they cannot tell what you know.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Which is why the questions have moved. CoderPad&#8217;s respondents named agent-generated solutions their top cheating concern at 52%, and the countermeasure most of them describe is not a detector \u2014 it is asking you to defend the code in front of them. A student who can say &#8220;this function is generated, I rewrote the retry logic because it swallowed the timeout, and here is the test that catches it&#8221; has answered the only question that mattered.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">The seven-step review habit that becomes your proof<\/h2>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Write the failing test before the prompt.<\/strong> If you cannot state what &#8220;correct&#8221; means, you cannot review the answer \u2014 you can only admire it.<\/li>\n\n\n\n<li><strong>Read every generated line before it is committed.<\/strong> Anything you would not be willing to explain out loud on a call does not go in.<\/li>\n\n\n\n<li><strong>Commit generated code separately from your edits.<\/strong> Two commits \u2014 &#8220;generated draft&#8221; then &#8220;fixes after review&#8221; \u2014 leave a public record of your judgement that no README claim can match.<\/li>\n\n\n\n<li><strong>Keep a rejects file.<\/strong> Three or four short notes on suggestions you turned down and why. This is the single most convincing artefact you can bring to an interview, and almost nobody has one.<\/li>\n\n\n\n<li><strong>Time one task honestly, with and without.<\/strong> Experts misjudged this badly; assume you are misjudging it too until you have measured it once.<\/li>\n\n\n\n<li><strong>Re-derive one hard part by hand.<\/strong> The trickiest piece in each project, rebuilt without assistance. That is the part you will be asked about.<\/li>\n\n\n\n<li><strong>Say what you used, in the PR description.<\/strong> Disclosure costs nothing with the 46% who allow it and earns credibility with the rest.<\/li>\n<\/ol>\n\n\n\n<h2 class=\"wp-block-heading\">Proof travels; claims do not<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Every habit above produces an artefact \u2014 a diff, a test, a note, a two-commit history \u2014 and artefacts are what survive the gap between your application and a founder&#8217;s attention. That is the premise Tierones runs on: students from IITs, NITs and IIITs matched to startups on real commits, shipped projects and a code walkthrough rather than a CV. The fastest version is to record the walkthrough \u2014 the argument for that is in <a href=\"https:\/\/tierones.io\/blog\/record-project-walkthrough-video\/\">six minutes of video is now your cheapest proof<\/a>, and the founder-side view of the same conversation in <a href=\"https:\/\/tierones.io\/blog\/project-walkthrough-interview-students\/\">the 2.5-minute interview format<\/a>. Neither asks you to stop using AI. They ask you to be the person who read the output.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">FAQ<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Should I use AI coding tools while building projects for my internship applications?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Yes, and hiding it is the worse strategy. With 84% of developers using or planning to use these tools, a founder assumes you did. What separates candidates is review \u2014 being able to say which parts you generated, what you changed and why. CoderPad&#8217;s 2026 survey found 66% of hiring leaders specifically want people who catch and fix AI mistakes.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Will using AI make me a worse programmer?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The evidence is narrower than either side claims. The CHI 2023 study of 69 novices found AI access improved code-authoring results without hurting manual code-modification performance \u2014 but every authoring task there was immediately followed by hand-written work. What no study defends is accepting output you never read. Read it, test it, and the tool is a multiplier.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Do companies let you use AI during technical interviews?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Increasingly, but far from universally, so ask before the call. CoderPad&#8217;s 2026 figures are 46% allowing it, 34% banning it and 20% deciding case by case; Karat&#8217;s survey of 400 engineering leaders still found 62% prohibiting it. Treat the rule as part of the brief \u2014 following it is itself a signal.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><em>Tierones matches students from IITs, NITs and IIITs with startups that hire on proof of work. <a href=\"https:\/\/tierones.io\/signup\">Create your profile<\/a> with your .ac.in email and your GitHub \u2014 the projects and the commits do the talking.
