    Solid Skill Testing Platform โ€” Good, but Not Perfect for Every Hiring Need

    Weโ€™ve been using TestGorilla as part of our hiring process to screen applicants before bringing them into interviews, and itโ€™s proven quite useful. The idea is simple but helpful: instead of spending hours reviewing resumes, you give candidates a relevant test right away. Seeing how people perform on real job-related tasks gives us a much clearer picture early on.

    The test library is broad, covering everything from coding challenges and software proficiency to logical thinking and communication skills. Setting up and sending tests doesnโ€™t take long, and the results are laid out in a clear way that makes comparison between applicants straightforward.

    Where it falls a bit short is in the depth of some tests โ€” a few feel like theyโ€™re too surface-level to really separate top performers from average ones. Creating your own custom assessments is possible, but the interface for doing that could use refinement. Also, once you scale up hiring, costs add up โ€” especially if every team needs access.

    Overall, TestGorilla adds real value to the recruiting process by helping weed out unfit candidates early and giving objective data on skills โ€” which is why I give it 4 out of 5 stars.

Besides, large businesses often receive a high volume of job applications.

TestGorilla mentions (1)

  • Need advice on hiring process for dev team
    What I had in mind was using either SHL-style aptitude tests, or third party assessments like testgorilla.com rather than a take-home exercise that I'd be moderating. I also remembered doing an online knowledge test of various web technologies when I used to be a web-dev - which could be useful for assessing Unity/C# knowledge. Source: almost 4 years ago

GStack mentions (4)

  • The most popular AI coding skills right now
    GStack is Garry Tan's Claude Code setup, and at nearly 110,000 stars it is one of the most popular skill collections out there. Instead of one mode that handles everything, it gives the agent distinct roles, each behind its own slash command. It has product vision, designer, engineering manager, release manager, doc engineer, QA, and post-launch retrospective. It is the same genre as Superpowers, a full workflow,... - Source: dev.to / about 1 month ago
  • GStack: Turn Claude Code Into a Full Engineering Team
    That is the design. And it is why GStack โ€” Garry Tan's open-source Claude Code skill setup โ€” has accumulated 82,700 stars and 12,000 forks on GitHub since its March 2026 launch. - Source: dev.to / 3 months ago
  • The YC President Endorsed an AI Memory System With Fake Benchmarks. He Also Shipped His Own. We Read the Code.
    This is not the first time. Tan's previous project, gstack, has amassed over 69,000 GitHub stars. Developer Mo Bitar described it as "a bunch of prompts in a folder." Another founder noted that without the YC title, it would not have made Product Hunt. A developer who examined Tan's AI-generated website code found 78,400 lines including empty CSS files, duplicate assets, and test files shipped to production. - Source: dev.to / 3 months ago
  • CFFBRW went from drag-and-drop to "hey AI, just deploy this for me"
    And I believe any builder should use Gstack from Garry Tan. Old news I know, but for people who live under a rock like I do. - Source: dev.to / 4 months ago
